once you pop those bolts on top of the engine expect reduced reliability and no more adding fuel from a local gas station when your riding..

for the average guy bolting on a pipe, filter and jetting to both the Raptor and YFZ.. you'll then find that the Raptor wont' even be in the same league.

 

I can't even get a Rappy to line up with me to shoot up China wall or Olds in Glamis .. wonder why?

Rappys had there time in history.. until the summer of the 2003 when the YFZ was introduced.. and I am sure in a few years the YFZ will have have its legacy come to an end also.

 

So are you saying that the Raptor won't be able to touch the performance of the same modded 450? or Vice Versa?

Whoah now. An 11:1 piston and stage 1 or 2 cam can be run with premium 93/4 octane pump gas. Heck, the yfz comes with 11.9:1 and you guys run premium pump too.

I'll call you on the "raptor not in the same league as yfz". Stock yfz has about 5-6 hp more than a yfz. Add 14hp for a rap pipe, and 10 for a yfz. (These are max claimed peak hp gain by pipe companies). Now you have 50-75lbs less weight and still a few hp advantage on the yfz, so it will be faster. However, it won't be out of the league. It still be only a few lengths in a drag, and just as close as anything else is when similarly modded.

 

That is correct.. the raptor with a pipe, K&N air filter, lid off and re-jetted will not touch a YFZ with the same identical mods.


The reason I mentioned this is that those are the bolt on mods that the average rider will make on their quad.

 

So will those mods on a Raptor beat a stock 450?

There you go again. Define "not in league" or "wont touch" for me and the rest of us. The yfz is faster, and even faster with mods. But it doesnt blow everything away like you would want us to believe.

A piped and filtered raptor will beat a stock yfz w/ similar riders. (typically,...que yfz owners who have killed everyone they have ever raced.)

 

I found that when my YFZ was completely stock, that a raptor with those mods would beat the YFZ on top end (and only on top end,, wasn't as quick off the line).. after nicking the shifter into 5th gear, the Raptor would start to pull away ..

NOW when comparing mine with identical mods to the Raptor on top end,, I can let the raptor get wound out on a dirt road and then just twist it to WOT and pull away very easily( 3 to 4 mph). This is with stock YFZ gearing and tires. The simple mods have more impact on the YFZ then the Raptor.

 

I'm new to this board to and i am looking for some info on whether to get a YFZ or a Raptor cuz i aint finding much comparison on either of them to each other...and im hopin to buy one this summer but i need some comparison from experienced riders. Info needed, Thank you in advance,

First things first, I ABSOLUTELY HATE THE WHINEY LITTLE KIDS COMPLAIN ABOUT HOW HARD THE SEAT IS!!! Don't buy the YFZ since the seat is so hard!!!! Second, YES, a YFZ is incredible on the trails!!! I'm not knocking on the Raptor by any means because its a Yamaha and look at what brand all 5 of my toys are, but come on now, your comparing a 660cc machine to a 450cc machine and the 450 beats it!!! That should say enough!!!
