The WR weight is not comparable to the CRF, since they are completely different applications. Where is the CRF's wide ratio trans, or the lighting coil, or the light, or kick stand, or ...... Get the point, we don't have a offroad version of the CRF to compare to. Now is the CRF really 233 lbs. I would guess Honda lied when they put together the specs. Maybe Yamaha did the same, so we compare the YZ weight to the CRF and there is ~15 lbs difference. Does that mean Honda is better, maybe but I would guess the 2003 YZ will have more to say about that. Yamaha has always use a 3 year plan to release new models (YZ426: 00, 01, 02) so what does 2003 hold I'm betting you will see a whole new product.
