Took the 450 out to el mirage for the first time to open it up. cheched my trail tech against a speed gun, pretty accurate... top speed of 77 mph @10500 rpm with 15t frant and stock tires. the bike seems to drop down on power at around 9k (need cams)... need more gearing, 36 rear? over all stll not impressed with this one. raced an 05 yfz w/intake and exh, and he pulled e in 4th very time

this thread has turned into a "my wooter is bigger then yours" argument...BEWARE!

yeah, but does it go fast!!!

my YFZ with just pipe/intake runs 82 mph on GPS with stock tires (pavement).

The stock KFX ran about 58mph in dirt. With mods (intake open, plug out and fuel controller) and a 33 rear sproket runs aprox 70 mph (GPS) in dirt. Stock 660 Raptor pull slightly from the KFX from a dead stop drag. Inches away on top end.

KFX is a joke unless most of your riding is below 55 mph

for some reason i dont think your right, and your comparing pavement to dirt. its known that a stock kfx tops out at around 69 mph on pavement, so if there is an 11mph difference do to the fact it was on dirt, then it would obvioulsly be much higher than 70 on pavement also. i believe it was PCamerica that had it running 83mph with 15t/34t, and around 77mph with just a 34t rear. a 15t in the front is a good improvement but not enough to get a good topspeed, just add a 36t rear to that and it will be good.

Haha! You are a joke...the races at Busco Beach were 600' races, you have to shift to 5th gear. The one against the 700r were 500' top of fourth, you can hear it. The renegade race was 350' though.

I mounted my handheld gps on the bars and in the dirt my max was 63, it's fully stock, I was a bit disappointed, I thought for sure I was in the tail end of the 60's..
