no riding

My friend out riding, he passes me almost before the end

[joe_389]

oh wut.. did he just scrub a 89 model kx500? damn that thing looks like it pulls hard.

[tyskorn]

If you ride an '89 kx500 are you supposed to be a goon who can't scrub?

[tyskorn]

And he said it was a '92.

[On The Pipe]

fail i just seen shadow posted it in sick videos before me
The guy in the video is racing that KX500 this weekend in the 450A class he probably will helmet cam it. Cycle Ranch is a good track for a 500 though pretty flat.

[KTM57]

OMG. He's probably racing it at the Pro Challenge. I'm going. Woohoo!

Any questions?

Who wants to get railed by a 20 year old bike?

Funny note, was running faster lap times on this bike than I was on my Dialed in 2010 CRF450.

I just think people should respect the Green Machine and ima make sure it happens at Round 6 Of the Main Event Series at Cycle Ranch MX Park this weekend by lining up in the 450 A class on her...

He only weighs 137.5lbs :O if he had some serious motor work done to that 500 it would make some serious power but just adding the pipe he has wakes it up a lot. If he wins on it everyone is going to be like wtf.

[KTM57]

Ah, nevermind. Would've been cool to see him race it, but he's not quick enough to run with the A class at such a big event.

[Phathry25]

That's what I was thinking myself.

Onto the next epic video... it has something for everyone here!...

For a 500 you're better off trying to smooth out the power, as Eric Geboers describes here -

The direction I went in, more than any other rider, was to make the power usable. I wanted all the power converted to acceleration. If I opened the throttle 20%, I wanted 20% of the power to the ground. This is very difficult to do with a 500cc two stroke. It is very easy to have so much power that it is impossible to control. With a 125 or even a 250 this is not such a big issue. But a 500 with uncontrollable power makes the chassis and the suspension bad as well. I wanted the shape of the powerband to be very linear. I got in many conflicts with the engine engineers at first. They wanted more compression and bigger carburetors for maximum power output, but this produced uncontrollable power. In theory it looked like the way to go. In reality on the racetrack it resulted in slower lap times.

Just before the Finnish Grand Prix, I suggested we do a blind test. I said," Build me three bikes and don't tell me what is on each bike. I will ride all three bikes during practice and I will tell you which bike has the smaller carburetor and low compression". They agreed. After riding all three bikes in practice I told them which one it was and I was right. My lap times were several seconds a lap quicker on that bike too. I opted for that setup on the Grand Prix bike. What really threw them out of their chairs is when I got the holeshot in both motos.

Nice read i enjoy anything about work bikes its always hard to find them online, cool website.

I wonder if that floppy front fender bothers him...
