A cheep thrashed ninja 650 could work.


Or a Harley 883... I've never seen myself on a Harley but I could make an exception for a flat track bike.


Maybe even a SV650 but they don't tend to be cheep enough.



This is a long way off but I wanted to get the ball rolling and hear your guys thoughts on it.

Thanks for looking.

Just did some searching and the picking are slim for a good bike I'll have to keep an eye out for a good candidate.
I do have my RD 350 that I could set up more street tracker but I would not be able to race it in a good class.


If I laced up a set of 19" wheels, make a new swing arm for for the bigger wheels, built a set of sweeper pipes and do a lot of suspension work it could be a fun hoon bike, must do some more research...

Check out this TZ250 flat tracker some thing along these lines.


Or this Kawi triple.


Or this R5 (I think)
