I have both a YFZ450 and a Raptor700 done for road legal use.
The Raptor is a WAAAAYYYYY better road machine.
My 200lb son and myself at 260, agree.
The YFZ is just a pure blast, but the alignment range can't seem to work for road use - it's twichy steering threatens to toss you off at any moment.
The Raptor is much more stable at speed.
Same Tire setup on both.
