I remember the build up, he had photos of the frame. Z50 backbone with the crf50 subframe area welded on to it. Even went to the hassle of getting an engineer to sign off on it. Seems like ALOT of stuffing around when you could have just bought a motovert rx or even a Yamoto complianced frame for less money. Technically even with all the work it will only ever be seen as a Z50 by rego authority. hk's right the honda one looked cool, this one looks like ass though. That being said, i do remember about 5 years ago on one of the aussie forums someone rego'd a crf50 by riveting on a z50 comp plate and stamping the headstem, dodgy....
