I still have a 07' and 09' dirt ones and a 08' supermoto. I love WR's. I purposely skipped the 12-15 models. It's not enough of a difference IMO and the fuel injection didn't look to help the hp at all.
I would disagree with this statement. The difference in power between my well jetted and deres tricked 09 and my 2012 was substantial. Would be nice if the 2016 offered a similar increase in performance which seems to be the consensus from most of the reviews I've been reading.
