The Virtual Motorcycle

The sedendary gamerz don't do well in VR - it demands some athleticism.
Our highest scorer on Space Pirate Trainer is a black belt.
I teach computer and software engineering when I'm not motorbiking.  This year I'm also doing a Ministry of Education grant on virtual reality research with some other teachers in my school board and it has left me wondering about how immersive simulation might work with motorcycles.

We have an Oculus Rift and an HTC Vive in our lab at school, so we can look into software development on two of the largest immersive virtual reality platforms.  VR has split into a couple of different camps.  You've got the cheap viewmaster style of VR like Google Cardboard that uses your smartphone to produce quick and easy 3d visual experiences.  At the other end of the spectrum you've got the fully immersive systems like our Vive, Oculus and Sony's PlaystationVR.  These systems are still pretty expensive, but they work surprisingly well for first generation devices - I often have students come out of them as though they are waking up surprised to find themselves back at school.  VR, whether it's a simple smartphone enabled device or the fully immersive kind, has a great deal of emotional impact.


Chris Milk, a music video director, gives you some deep, professional insights into immersive video; it isn't the next medium, it's the last medium.

How could VR be used in the motorcycle industry?  If you want to see a new bike in 3D to get a sense of what it looks like in the flesh, looking at it on a 2D monitor won't do a good job.  Google cardboard and a smartphone are all you need to see in 3D.  If that isn't a cheap and obvious tool for dealers looking to advertise motorcycles, I don't know what is - Jaguar is already doing it.  I suspect you're going to start seeing simple VR viewing kits included in smartphone packages in the future as the advertising power of immersive medium becomes more apparent.

I got this on email from Telus six hours after posting this story - am I good or what?

The immersive simulation served up in VR has real emotional impact on customers looking to make a decision.  You wouldn't be limited to a bike model either.  Taking a 360° video of a walk through of your showroom would allow customers to virtually see many bikes in 3d along with having a sales presence at their beck and call with no threat of pressure.  Virtually checking out a showroom before you make the trip over there is going to be a key sales hook in the future.

Virtually experiencing the factory where your favorite manufacturer produces your dream machine?  Can you imagine the brand loyalty generated?  VR is an intensely personal experience - your fans would feel like they had been on a VIP tour after that.  This kind of intimacy in marketing has a powerful effect.

Beyond the 3d imaging offered by basic VR, fully immersive systems offer a level of experiential training that is otherwise cost prohibitive.  The thousand dollar headsets might seem expensive, but last year at the Skills Canada National Competition I was talking to a company that makes tree harvesting systems for the forestry industry.  These mechanized systems cost hundreds of thousands of dollars.  Up until the past couple of years a new operator had to learn by sitting in the real deal.  When they broke blades or damaged robotic arms it cost big money in both equipment and lost harvesting time.  At last year's Skills Competition they had one of their new VR training systems - an operator's chair surrounded by an accurate recreation of the physical controls hooked up to a VR headset.  Suddenly you're in a forest grabbing trees with a million dollar tool and learning how to best operate the machine.  They could simulate failures and varying conditions as well.  These $10,000 a seat systems saved millions in their first year of use.  New operators could spend many hours learning the system before ever setting foot in the real thing, and poor operators could be selected out before ever doing any damage.

Riders seldom get a chance to ride a bike before they buy them.  VR could change all that.  A system of wireless sensors could be attached to any motorcycle in the showroom.  With the bike wheel locked onto a simple pitch/yaw/roll mechanism, you could experience the ergonomics of your specific machine without ever turning over the engine.  Specs could then be loaded into the VR simulator and then you go for a ride, virtually.  You would get a personalized, immersive audio and visual experience while feeling how you fit on the machine without using any gas or depreciating any new model.  This kind of experience is very engaging.  I suspect the sales rate after such a VRride would be exceptional - it would also be a draw to get customers into the showroom.

Specialized simulators for racing are another obvious training tool.  Riding and racing schools, teams and other specialists could offer VR as a first, less expensive step into everything from working out the basic controls of the machine for a beginner to Jorge Lorenzo trying various lines around a track while experiencing suspension and engine setting changes before doing it in the flesh.

Even the first generation immersive VR systems we have now would be capable of offering this level of training.  They've only been out for a year or so (we ordered our Vive last April), but the possibilities around this emerging technology make my glad I have early adopter experience with it.  A couple of students dropped by the lab the other day wanting to try it out (it generates buzz even in students not taking computer tech).  After half an hour trying out Tiltbrush, Google Earth and our new Oculus handsets one of the girls took the headset off with stars in her eyes and said, "wow!  This is the future!"



In five years it is entirely possible that tens of thousands of people will have a much more intimate idea of what it feels like to be Valentino Rossi on a perfectly tuned Yamaha M1.  Pretty cool, eh?

Naked Connie: 3d modelling customized motorcycle bodywork

I've re-3d-scanned the stripped down ZG1000 Kawasaki Concours in order to better work out what the rear lights will look like.  You can wheel in and out and manipulate that model below with a mouse.  The scanner did a bunch of software updates which led to a much higher resolution 3d image.




I modelled it with the stock seat on with an eye to taking the pillion seat off and building a very minimal back end.  With some careful cutting I'll be able to use the seat dimensions to figure out how best to render the rear light assembly.  I've been doing 2-d drawings but they don't deal with the 3d complexities of the real thing.  I'm hoping this solves that.




Using the 3d scanner with cardboard body panel templates gives you a pretty good idea of how it will look when it's done.




As far as electronic parts go, I think it's time to get the lights sorted out.  At the moment I'm looking at some integrated LED head and tail lights to minimize stalks sticking out of the bodywork.

ZG1K: Customization, Inspiration & Aesthetics

Graphical thoughts on the ZG1K customization...

I'm still working through the proportions of a naked Concours.  It isn't a delicate device...

In spite of the colourful nature of the bike, it's a muscular heavyweight.
Inspirations for this build revolve around 80's sport bikes and naked streetfighters.  I grew up in the '80s and have a thing for fully faired race bikes with blocky rear ends.  The big, bulky Concours' tank lends itself to a strong, balanced back end.

A box shaped rear fairing working off and 80's race bike vibe combined with a minimalist cafe racer look



The paint's already coming off the tank.  I need to figure out how to make a rough 3d outline of the rear body work (cardboard, wood, thin metal?) in order to begin getting an accurate sense of how the back end will look.  If I can get handier with 3d editing software I'll 3d print a few various prototypes first (maybe scan it with cardboard panels in place).

The front fairing will be a minimal street-fighter type of thing.  I wanted to go with a bikini fairing, but it's a bit too delicate for the big shoulders of the Concours.  Monkeying around in Photoshop has gotten me this far:



But this is more of a sculpting thing than a pen and paper thing.  I need to make some cardboard outlines and see what feels right in 3d (Close Encounters style).

The Mike Tyson/heavyweight feel of the Concours means I'm thinking more melee fighter than I am lightweight and delicate.

ZG1K: A Customized Kawasaki Concours

I've stripped down the Concours to the bare bones.  From there I intend to build it back out into a cafe-racer/naked streetfighter.  A barebones ZG1000 Concours looks pretty butch:

The brown seat will sync with
a crimson stripe.  Were money
less of an issue I'd get it custom
upholstered to run the stripe all
the way through.
The back end is going to get tidied up and topped with a cafe style brown leather seat.  I'm also researching LED light systems that will be all but invisible under the seat until they light up.

The front end is going to get a basic/minimalist light cover and a light that has indicators built in for a clean look our front (no indicator storks poking out).  The front fairing and light will be mounted to the forks.


Stripping on the Ducati Monster is
a thing of beauty.
As for paint colours, I'd like to try and take the tank back to metal and then have a crimson stripe running over the minimal front fairing, along the tank and across the minimal rear body work.  An asymmetrical design with a thick centre strip and a thinner stripe off to the right is what I'm currently thinking, though I'll see what works as the bike comes back together.  If the tank is too rough I'll redo it red with a gold stripe that matches the wheels.  Now that I say that, it might be what happens anyway.


I'm going to use the Structure Sensor scans to map out body work in 3d.  I'm also going to make use of a Dremel 3d printer to print out scale replicas of different body configurations.  These are some screen grabs of the 3d scan (which you can see at the top).











The massive twin exhausts might get modified, but right now I'm enjoying the big-guns look they have, so I'll probably be keeping it.  They help visually balance a bike that looks otherwise top heavy with that massive gas tank.


First go at a logo - I think I'm going to have to find the Kawasaki Heavy Industries
logo for this heavyweight streetfighter.

Things You Want To Do In Your 40s

Work for myself so I don't have to work for some myopic middle manager more interested in climbing than doing the right thing?  Yeah, that'd be nice.  Work on something as hard as I can knowing that no one else can walk in on a whim and derail it?  That'd be nice too.  Challenge my technical skills and develop my diverse talents to new levels of excellence?  That'd be awesome.  Have the means to fearlessly explore technology and the world around us?  Brilliant!

$1.3 million doesn't sound like a lot of money but it would mean a thousand bucks a week until I'm 75 years old.  Somebody better at math and competent with investments could probably figure out a more accurate, lower amount that would do the same thing.  It's comfortably middle-class, but I don't really dream of being rich, I dream of being free from work to pursue my passions.  If I could pull that off what would I do with my time?  It's kind of like retirement, but I want to do it now while I'm still able to do something useful with it.  I don't think I ever want to retire.
Mechanical Sympathy would expand and become an
income stream of its own. It would be the centre of
an online media onslaught!

Here's what I'd aim at if I weren't busy pulling the plough:


MEDIA MAKER

Writer:  I'd exercise the English degree and write, but not in a specific genre.  I'd pursue motorcycle and travel writing more aggressively.  I'd be happiest freelancing and working once or twice a month on assignment with the occasional larger travel project which would lead to a book.  Lois Pryce is a role model.  While that wasn't happening I'd be writing fictional novels.  It would be nice to work for established publications, but developing my own brand online would allow for more control over what I'm creating.  I've been working in large bureaucracies for too long.

If it's new and technically challenging I'm into it. 
Having access to that kind of kit is exciting.
I like to be surprised by what new tech can do.
Photographer:  The goal would be to have the work pay for the gear, and the gear I'm looking for is pretty technical.  I'd like to have professional quality photo and video gear on hand, as well as technically challenging tools like aerial drones, full spectrum and 360° virtual reality cameras to test limits and produce original, even experimental work.  If it's new and technically challenging I'm into it, especially if it probably won't work the first time.

Digital Media:  Exploring digital media has long been an interest (I teach it now).  Having access to the latest tech, not to consume but to experiment and explore, would be fantastic.  Projects would include VR environment building in CAD and simulation, as well as immersive media creation.  I'm working on a VR research project in school at the moment.  I feel like major breakthroughs are currently happening there.  What we have in ten years will make our screen use today look archaic.



TECHNOLOGIST

I got into 3d scanning last year.  The resolution isn't
spectacular, but it's amazing what you can do with
a simple 3d scanner on an ipad.
Mechanic:  I've dusted off old mechanical skills with motorcycling, along with some long unused artistic urges.  Customizing motorbikes is an elegant way to combine left brained aesthetic creativity with right brained mechanical expertise; it's a whole brain hobby!  Having enough time, space and money on hand to chase down old bikes and see customizations through to completion would be grist for the writing and photography mill.

Digital Engineering:  I'm especially interested in micro-manufacturing using digital tools.  Multi-axis milling machines using CAD models offer new avenues into high-tech customization.  3d printers are making advances every day.  Being able to print my own fairing designs would be brilliant.  Being able to print my own designs with dragon scales would be even better.

An opportunity to borrow new technology and see what it is capable of would also be grist for writing and media creation.  If in the process I happened to get very good at producing customized parts, I'd lease the gear and get to it.  As prices fall on what was once expensive industrial grade equipment and digital management makes high tolerance production available to everyone, a new post-industrial age of customization will emerge.



Kawasaki's H2 supercharger impeller is a thing of beauty.
The technology that built it is becoming more accessible every day.

With table top laser cutters and various other digital tools becoming commonplace, the chance to explore these technologies without safety nannies hand wringing from above would be delightful.  The home garage of the future is going to be a magical place of customized, personal manufacturing.  It would be a blast to have the time and means to explore it.

I really do enjoy teaching, but the vampiric bureaucracies that manage it make working in education feel like giving blood; you're doing a good thing but you always come out feeling drained.  I'd happily take in apprentices on my own terms and genuinely enjoy helping them discover and develop their talents, I just wouldn't want to do it in an institution of learning.

One of the things I want to do in my forties is stop others from diluting my focus and wasting my time with their own mediocre expectations.

Motorcycle Parts Fabrication: CBR900RR Chainguard DIY on a 3d printer

The 1997 Honda CBR900RR didn't come with a chainguard, so I thought I'd 3d model one, but I wasn't sure what they looked like, so I did a bit of research.

Honda used the same chainguard on all the mid-late 90s CBRs, so if I can find a CBR600 F2 or F3 or a CBR900, they'd all fit.  If I can't find one I'll cabricate one.

Print that scaled to a 14cm on-centre gap between the mounting holes and it should fit like a glove.  Time to see if we can fabricate something!

'97 CBR900RR LED Indicators and Rubber Parts

The Fireblade project has the main bits (fuel leak leading to an engine drowned in gasoline) fixed with a carb rebuild and a new petcock.  But there are lots of bits and pieces to sort out before I go get it safetied and put on the road.

The weather warms up tomorrow so I'm hoping for a ride, but Saturday was a -20° March 7th kinda day, so into the garage I went to get the little details worked out.

I was initially going to hold off on the LED indicators, but dead bulbs and broken covers on a 23 year old motorcycle meant the LEDs were actually the cheaper, easier and more modern looking fix anyway.  I'd brought a second set when I got the ones for the Tiger, and also got an adjustable indicator relay, so I had all the parts on hand.






The rear indicators look like they were attached by a monkey.  I ended up pulling them all off and removing all the stripped, half installed wood screws that were holding them in.  I then drilled a hole in the rear plastic under-tray and mounted the second set of LEDs I had on hand from the Tiger upgrade.




The wiring was pretty straight forward with green being ground on both indicators (connected to black on the LED) an orange to LED power (yellow) on one side and light blue to LED power (yellow) on the other.  The LEDs also have brake light function where they strobe when you first press the brake.  Both red cables on the LEDs go together into the middle pin on the brake lights.  It works a trick:

Some other odds and ends are also proving troublesome.  Living in rural Canada means everyone's still in love with imperial sized fasteners.  All our local hardware stores have rows of 'em, and maybe 2 metric bolts.  It was tricky figuring out the sizes of missing fasteners anyway, but some internet research into OEM parts supplier parts listings got me this far:



https://www.megazip.net/zapchasti-dlya-motocyklov/honda/cbr900rr-14743/cbr900rr-cbr954rr-fire-blade-28645/cbr900rrv-713455

Bolts to hold down the fuel tank:
96300-0604007
Bolt, flange (6x40)


Other metric sized bolts in the same assembly:
BOLT, FLANGE (6X20)

BOLT, FLANGE, 6X32 CBR900RR FIREBLADE 1997 (V) CANADA


A 6x40 metric bold means (as I understand it) a 6mm wide bolt that is 40mm long.  But metric sizing also looks like M6x40. I'm assuming their the same but don't understand why there isn't a consistent format for metric bolt sizing.

Some other resources around motorcycle fasteners:

https://www.webbikeworld.com/motorcycle-nuts-bolts-fasteners/

Lots of links to other websites.

https://www.boltdepot.com/fastener-information/Type-Chart.aspx

The bolts into the frame that hold down the fuel tank and the brace for the windshield are 6x40, but I couldn't get an M6 bolt in there.  I ended up cleaning out the thread by tapping it out again and then it went in nicely.

Rubber parts are particularly hard to find on this kind of bike - it's just old enough for existing stock to be gone and just young enough not to have a classic aftermarket parts ecosystem.

The cracked airbox rubber connector to the carbs is nearly impossible to find.  The only
online place I can find them is for a full set of four plus shipping from Europe and ends up at over 70 Euro ($110CAD)... and I only need one of the damned things!

I'm looking into some cunning fabrication options.  Some people have tried plumbing PBC couplings as a kind of secure bandage over the original rubber tube.  Though if I can find one that is the right diameter and well put together I might simply be able to trim it and substitute it.

Others have tried various fixes like heat shrink or inner tubes.  I'll do some more research and figure out next steps...



These guys suggest silicon hose as a temporary measure.  Since what I need is on the airbox side (I was easily able to get carb side rubber replacements), it shouldn't see too much gasoline so the silicon fix might be the quickest way forward.

These guys suggest a sealant.  Again, because it's not on the carb side this might do the trick.  In terms of cost this is the cheapest fix, so I'll probably start here and see how it goes.

I'm wondering if I can't 3d print the correct part.  There are flexible materials we can use to print objects using a 3d printer.  I suspect we're only a few years away from having a 3d printer in our garages that can print these rare parts out of flexible filaments:
