nice build, very reminiscent of the Mclarney bikes, no longer made, now the main ones to have are the TT SB-5 or the KP11e
sold all my race bikes as I couldnt make any of the races last season, dates all fell on other commitments, hoping to get back out next season
stock bikes with 27t silver can motors I get about 30mph down the straights, the lipo brushless superbikes do 50+ easily on the main straights, thats checked with radar or over a speed trap in the track
if your interested in maybe selling one, I might be interested in testing it and racing it next season, dependant on pricing, will need double sided swing arm and decent USD forks to get it handling better, but that easy to sort
you might want to try the bike, then try it with the steering setup with the twin springs, and a seperate damper if its required.
