I love people who talk about things they dont know anything about.
I own both modded raptor and a stock yfz450 I let a buddy ride my raptor and smoke him every time.
And yes we swap bike same conclusion.

 

I don't believe this for a minute.

 

I have beat every yfz I have ever raced on my 01 Raptor( but only by a half bike length on a 150 yrd track)

 

I did an uphill sand drag on my old Raptor (01 with exhaust) and raced a stock YFZ and i didnt have any problems beating it. I know that not stock for stock but my pipe couldnt have done that much could it???

 

The YZF? or the YFZ? because there is a small difference I think it was YZ450F which is a dirt bike and the 450 is the other yamaha quadc that isnt a Raptor.

A Raptor stock can't beat a 450 stock I've seen many a race but Souped up Rappys kill 450. It all depends.

 

It better be real souped up if its going to kill it.

 

i dont know what im talking about?, hmmm fully mod both machines and dyno them, then tell me which one has more hp......

 

then after you figure out horse power weigh them then figure out the power to weight ratio

 

Little kids, HP is not everything, just a little fraction of what it takes to have a fast bike. Setup, rider, state of tune, to name a few......

 

just about to write that.
