well, it's not a motocross, but it is still a yz450f!
when I bought it, i directly put my CRF wheels on (yes it is almost plug and play!)
being an Ex-honda rider, I couldn't bear the blue color , so i changed it
with a home mode air duct (not working well for the moment, still being under development and test)
some other nice features
and a dyno test (rear wheel measurement! Green is stock with stock map, red yosh slip-on with Jay marmont map and blue is yosh slip on + custom map! I need more power at top end (for supermoto), any ideas? hot cam stage 2 or above?)
