Travelling Ninja
A Vicious Cycle got me the kit for the topbox mighty quick (the day before they said it would get here). It was a quick fit and install. With the topbox and backrest in place, my son has a much more comfortable pillion to sit on. A Vicious Cycle makes it easy to get sorted with the right kit, letting you search by bike and get kit specific to your machine.
The setup is very solid. The Givi monolock seems very stable and the frame was all first rate. There were no problems with installing it.
The 26l topbox might seem small, but for a svelt bike like a 650r Ninja, it's a well proportioned fit.
$320 all in (including shipping & taxes) for the Kappa case, the Ninja specific mounting bracket and the Givi monolock base.
