I haven't ridden either, though wouldn't a suspension upgrade help? the new 300L has better low end torque, it weights 306lbs wet, and the WRR is 295lbs, how would 11lbs make it way heavier?
I'm just comparing it to the $9k example posted, I am a huge WRR fan. Just wondering why proper suspension, bringing the 300L to $9k equal, wouldn't be a better bike. I know ground clearance is a little less
I haven't taken a look at the 300, but the 250L was 325 lbs wet. And the power was down from the WRR as well, so the whole power-to-weight ratio strongly favoured the WRR. Plus you could wring additional hp from the Yami with cheap mods, harder to do with the CRF.
It's just not a good base to start off with if you're looking for a real dual-purpose bike.
