Let me tell you now that my bike is a mid to high range thumper and straight of the line im in the lead, but as soon as i hit 6th gear and rev it out the newer bikes take over on top speed. On tight cornered dirt tracks with short straits I almost always win the race, almost meaning, out of 10 races i win 7.
Any suggestions on how to gain top speed?

nephron said:cnielse5---don't know if it's overblown or what, but Kawasaki claims(ed) the KX500 makes 65 at the crank. The 51 for the CR500 was probably at the rear wheel? At any rate, riding side by side with 450F's, there's no comparison. Doesn't matter to me if this thing only makes 40hp, it still makes me smile a lot. :)
this is an interesting thread. now going by numbers I would say that the newer Bikes are far more powerful. I heard once that a cr 500 made 51 hp in it's last conception. I read some where that the 05 CRF 450 makes 55HP, and I Know a guy that works at the KTM plant in ohio and he told me that the 03 SX 250 made 53 hp. so going buy the numbers the newer bikes are much better.
I've got a 89 CR500 that is a beast. It will keep on singing right past a CRF450. An article in Dirt Rider stated they made a "modified" CRF 450 with 53 or 54 to the rear wheel. The test riders complained they could not handle it. My 500 makes that power stock....how about a port job......pipe and after market reed block. Now I am pushing around 62 hp and at a fraction of the cost to modify a CRF. The 86 CR500 was the hardest hitting CR500 produced. It was hard to hang on to. Honda spent the next 10 years detuning the CR500. My bone stock 2001 CR500 is a blast to ride... very fast with nice boingers. Even tho, I feel my 89 500 (even when it was in stock fashion) hit harder than my 01. I definately feel faster on my 89. But on the flip side, I have had to have my 89's suspension worked over. All the hp in the world and your suspension holds you back...kinda pointless.cnielse5 said:this is an interesting thread. now going by numbers I would say that the newer Bikes are far more powerful.

I'll take a new bike over an old bike anyday.
