I have been searching for a track bike for a while. I am surprised at the over inflated price of most of what I see as far as stat right off bikes. I don't quite understand why they are so expensive. Anyway I am a little uncomfortable about posting this and have read the rules of this site and didn't see anything that looks like a red flag but if there is mods feel free to delete if this is inappropriate. I found a track bike for sale on a commonly known internet sight. I viewed the bike a couple of times , although a little rough around the edges the motor was strong brakes etc all checked out. It is kitted out with quality race slicks frame sliders and is ready to ride so ticked all the boxes. The seller was a little tentative about showing me documents to its history and always kept promising to email them but didn't . Eventually showing some paper work scanned on his phone. He promised the bike was solid and no problems. The price was low and I made a really low ball offer and he didn't knock me back. I was ready to hand over the hard earned but said I wanted my mate mechanic to check it out,who has a lot of experience with track/race bikes. As no rego so no test on the street he ran it on the dyno to see what was up. It tried to jump off the dyno on throttle , the frame is completely twisted with wheels not in line rendering the bike quite dangerous , rolling off the throttle at high speed could result in the bike tying its self in knots and throwing me off. Clearly its buyer beware and there is no recourse in matters such as these but with a fairly competent eye and with some mechanical knowledge I still got it wrong. Now this guy will sell it to someone else so I fear for their safety . I am not about to disclose details publicly but if you are thinking of buying a track bike feel free to P.M. and i will give you more details.
