I've been reading a lot about people stuffing the Honda CB500 twin into the CRF250L frame and I want to do a Yam version, so despite this being a TTR forum, I'm hoping someone might have wider knowledge of donor bikes (UK only!!)
I'm after a steel frame WR250f/450f rolling chassis, as new as possible (was 2006 the last steel year?) and a running YZF R3 or MT03 (needs engine, throttle bodies, loom, ecu etc so basically a complete crash-damaged bike - it's a "my first motorbike" type, so there must be bent ones all over the place? Except on ebay it seems!)
It makes a fine lightish weight adventure bike in the CRF250L frame - infinitely more capable than the Af Twin monstrosity. I nearly started buying the bits to build one but couldn't lower myself to buying a CRF - cheap and nasty suspension, heavy frame, wrong colour... (not blue!!)
Best thing Honda did for years is start making the cb500x its a cracking long trip bike the cb500 twin motor is sweet yes I used to have the 1999 model
