Tiger Pre-Flight Checks

I've never monkeyed with the suspension on the Tiger, but since I'm a 250lber and I ride 2-up with my son who's an easy 130lbs, I thought I'd look into setting the suspension before our 1500km round-Huron trip.

A kindly Dubliner on Triumphrat had a copy of the owner's manual page that explains how to set the Tiger's rear suspension.  A two-up loaded bike should be spring pre-load set to the highest setting (5), while the rebound damping should be set three clicks out from all the way in.


Making the changes was pretty straightforward.  The spring pre-load adjuster is easily accessible under the seat.  The numbers on it are bit tricky to see, but you can quickly set the pre-load to the desired setting once you find them at the bottom of the cylinder.

The rebound damping adjuster is at the bottom of the shock and easily accessible.  Turning it in until it was snug was straight forward and the clicks are loud and easily detectable.  Turning it out three clicks was an obvious process.

I took the bike for a ride today to get gas and prep for the trip.  It feels firmer, less bouncy and taller than before.  I'm enjoying the change.

Once back I set the tyre pressures to 36psi front and 42psi back and looked over the tires for any issues.  I've spent the rest of the day packing as if for a portage canoe trip (packing for a long bike ride is similar).

While out and about I stopped in at Two Wheel Motorsport and picked up an Airhawk.  I'd been thinking about getting one anyway after the nasty case of monkey-butt I got riding it to The Bruce last week.  The gel pad I was using gets moved to the pillion seat, so everyone gets a seat upgrade.

Airhawk pricing is a bit baffling.  The tiny dual-sport seat (11.5" deep x11" wide) cost $230, the much larger medium cruiser seat pad (14" x 14") costs $148.  We tried out the medium cruiser sized one and it fit the Tiger seat better anyway, so I saved myself eighty bucks and purchased the larger pad. (?)  I'll give an update after I put an intensive 1500kms in unbelievable heat on it.

While I was under the seat I found the height settings on it, so I moved it up one from minimum.  It might quickly find its way to the top setting, but middle with the Airhawk has already relaxed my knees dramatically, just in time for a Great Lake ride-around.

Kawasaki KLX250 Suspension Adjustment

I can pick the thing up, so lifting up the wheels isn't the ordeal
it is on the massive Concours. To get both wheels up I used
a wooden box on a jack and some jack stands on the back.
Today I had a go at the suspension of the KLX250.  The previous owner is a much smaller fellow than me, so he had the suspension at stock levels (preset for a 150lb rider with no luggage or passenger).  For a big guy like me (6'3", 240lbs) the front was wallowy and the back felt loose.

The suspension adjustments are on the bottom of the forks at the front.  The rear has rebound damping down at the bottom of the shock and compression dampening at the top.


I've included photos of each below.  Tightening up the suspension was quick and relatively painless.  The clicks are obvious and about half a turn of the screwdriver each.  After cleaning up with wd40, I had no trouble turning any of them.

front forks

On the bottom of the front forks you'll find a hexagonal opening.  There is a rubber cover in there.  It's designed with a flat edge and pops out easily with a small, flat screwdriver.  Inside you'll see a small, flat headed bolt.  Each half turn creates an obvious click.  I turned each side clockwise four clicks.  No more wallowing, and the forks feel tighter on cornering.  On braking I get a single, less pronounced drop.  That was a quick fix.

The rebound damping adjuster is on the side of the bottom of the shock housing.  It gets dirty under there so wiping it down first helps in finding things.  It's easy to get a flat screwdriver on the adjuster bolt, and it turns easily. The clicks are obvious, I turned it up (clockwise) four clicks.

The compression damping adjuster is obvious behind the cutout in the fairing.  It was tucked in behind an electrical connector on mine which easily pushed aside.  Since it's out of the muck, this one doesn't get dirty.  The clicks were again obvious - I turned this one up four clicks as well.

I then took the bike for a quick ride to get gas.  On the road it corners more tightly with none of the previous wallow.  On the way back I tried to ride as directly as I could rather than follow the roads.  I got to the end of pavement in a subdivision and found myself on a deeply rutted dirt road which led to a hydro station.  I then nipped down a walking path to the road behind my subdivision.  This bike is so quiet a rabbit was surprised when I puttered by.  There is a large dirt pile where I came out of the bush so I zipped up it and back.  Off road the bike is much tighter.  There is still a lot of suspension travel, but I could feel what the wheels were doing much more clearly, the bike just feels tighter.  I was just hoping to calm the wallow.  That happened, but the whole bike dynamically feels so much more suited to me now.

Now that I know where the bits and pieces are, I'm intending to keep monkeying with the settings to get it customized to my size and preferences.  With the settings that easy to play with, why not?
