My 06' X Is Faster Than a 2011 Fuel Injected KX450F

[2006450X]

Raced my riding buddies 2011 KX450F at the St. Anthony Sand Dunes and won!!! He has an FMF slip on. I have full FMF, air box mod, ported heads, R-Cam. Just thought i'd share, I was pumped. Wasn't incredibly faster but it was.

i bet he had track gearing and you didn't ?

True but it was a race uphill, and I only got up to third.

The KXF makes more power than the X.

Going faster is all rider ability.

His in near stock, mine isn't. I also rode his and they feel nearly identical to me, on the sand atleast.

Hard to compare a stock X to a stock KXF as the X is a dog until rejetted and uncorked. The KXF is a MX bike ready to race. The X definitely has a higher top speed just because of the wide ratio tranny. I've ridden both in the desert and the X feels faster and more stable at high speed. The KXF feels more torquey.

Interesting. I was at a dune park in Colorado and this douche in a polo shirt, sneakers and no helmet on a yz450 smoked the crap out of my brother's X and my X. I'm thinking he had to have something going on with his gearing. He was gone before I was in 2nd. Sadly flat area everyone was dragging was not long enough for me to get into 5th.

I do recall we changed our gearing so we could fit paddle tires on so they would not hit the swing arm.. Wish I could remember how we changed them.

Maybe the X is different, but in general if you are dragging racing, it is always better to start in 2nd gear. I'm sure that is probably what the guy on the YZ did, because that is the gear I would be in when taking off. Starting off in 1st gear will only result in way too much wheel speed, with little movement & then an almost immediate shift into 2nd, by this time the guy is already gone. Whereas starting in 2nd gets the wheels spinning, but at the same time hooking up & moving forward. Try it next time & I bet you do much better in a straight away race.

yea 2nd gear starts are the way to go!

Another tomato vs green apple comparison. My bikes faster than all those. ...probably with my girl riding it.
