Got some bad news for you DC
My WR125R is based on the Yamaha WR enduro series
It is so close to 15bhp that it hurts and it is the only 4stroke that I know of that can be de-restricted (Mine isn't as that would be illegal
)
It has the same engine as the R1 and you know what that is like
I really can't believe it is as quick as it is (not fast only 70) but it gets to 40 so quick it is ideal through London traffic
And I've already stood it on it's nose twice by accident just stopping
It's so much fun through rush hour best discription is it's like a Wasp on Steroids
Also at 6ft 4" and 17 stone I would look a bit silly on one like yours
