here is a 50 that came through my shop once, the guy wanted a big engine, but I told him i could do him something better.
mods:
wheelie bar
hyper spoiler, custom designed by an aerospace mate of mine that works at NASA.
billet titanium turbo, Nissan were testing these on the new GTR, but they used something else, so i managed to pick up a few of their spares.
I have replaced the shock with a Nitrous oxide canister, you can still do jumps, you just have to be smooth, like ricky charmichael.
and also has limited edition pink handlebar streamers, just to help with the ladies. (not that you would need it with one of my machines
it puts out about 95.7 BHP on my dyno at the moment. not bad for a 125.
