Engine Rebuild for $3000 sounds like dirt cheap ( all depends what kinda mod ) if you make the money back by winning the race or something .. its totally worth it

 

Amazing wheels. (and DAMN are those things expensive!) Those wheels are so much lighter than stock too.

 

Sponsorship helps... a lot,and allowed Supersport modifications are are pretty minor compared to a full superbike spec motor, which would run from $5000(on the low side)on up!

 

probably suspension/set up stuff, I've spend around $1600 with GMD setting up/straightening parts on my SV and getting the right geometry
I don't spend too much on my bikes though, I bought the SV ready to race andits already plenty fast for its class and I've only used the F4i for trackdays so far. I put a lot of parts on it but most weren't expensive. Bought the ohlins shock used and saved a good bit (had to have it rebuilt with a new spring right away though), bought a couple lightweight subframes but they used my stock subframe to design it so I got those for dirt cheap. Still just use a slip-on

I'd like to get some aftermarket wheels like that, definitely badass but I decided to save money for school rather than spending it on bikes (I'm sellin a couple bikes now)
