2003 Honda XR50
I bought this bike to have to mess around on, cruise around the pits at the track (which I have yet to do), and ride at the local XR50 track.
To start off I added a Fast 50's BMX bar kit, I shock and new fork springs. Overall it added about 2" of lift making it the perfect size for me at 6' tall. The rev limiter was removed and I added an extended folding shifter.
Don't get me wrong, I weigh in just shy of 200 pounds, and this bike is still peppy enough to pull second gear wheelies, go about 35 mph, and throw me off without hesitation. Thats what made it so fun. I rode it a countless times and raced it once before it met its untimely death. If you have a grand burning a hole in your pocket like I did, I wouldnt hesitate to buy one. Pit bikes truely are the most fun on 2 wheels.
BTW this bike is now my project bike: Coming soon- fast 50's frame/swingarm, red baron fork extenders, BBR pipe, and takegawa 88cc bigbore kit are all on the way. It should be done by the end of summer.
