I got a 2004 YFZ 450 and the motor and case has all been rebuilt to 2007 spec so it is a true 450, still has the 04 head which has been ported and polished, it has a brand new hot rod crank, it has 3 inch header pipe + exhaust out to a muffler, RON WOODS pipe and intake tube, K&N filter, and I have been riding for 7 years. My friend just bought a new 08 can am and its still all bone stock, he thinks he can take me out, what do you guys think?

 

If you have a good set of tires... I don't see how he could... Unfortunately that's only based off of what I have read. Nobody around here even has a ds450...

 

i take em stock on the drag strip but now i just kill themn

 

HMMMM a bike with mods vs a bike with no mods? i wonder who is going to win. I havent raced a 450 with mine yet. but my ds450 will take a piped predator pretty easily, a few lengths in 300ft.

obviously you will win if your bike has those mods.
