So, looking at Yamaha SR400s and SR500s. Probably one of these bikes will be my next. But looking at them online, I can't help but wonder if you could squeeze a SR400 motor into a TW200 frame. I mean, they're both Yamahas and the engine profile looks very similar. Anyone out there know if anyone has tried this or am I just thinking crazy?
