LAUNCH LEVER!!! i got one on my peugeot. probably the funnest 20 bucks i spent ever. unless your going to kit your bike and really start spending a lot of loot, i would just stay stock.
if you want to pedal it just pop the belt off. my pedal/drive switch still kinda works but if you just pull the spring back and pop the belt off it pedals better than anything.
those clutchless variators reqire you to get a clutch-pulley. i guess the variator in there is so beefed up it takes up too much space to have the clutch in there w/ it. but i don't really know. mine is stock. i'm pushing 40 on stockish shit. i love my 103!
