Tri-z 500?

Sand is the great equalizer... A 500 is still king of the dunes...

All three of you guys (Red Rider, Louis, and CR 480) make very good points. I personally don't think there are any 4 stroke dirtbikes that can keep up with a properly running 500. They're just ridiculous.

hehe, i beg to differ, just to stir the pot, a well strung 4 stroke will spank a 500 2 stroke in smr,,,, and bout anything else...iv had the 500's and now have a 450...it Spanks my buddys Ported, done to the nuts kx500, he went and bought a 450 too and is much happier....

then your buddy cant ride.

I second that motion, ummm. Whats smr? lol. You gota spend a lot of money to get a trx450 to even remotely touch a 500 in a straight line.

Like I said before though, the big 2 strokes take a lot out of you so its hard to ride consistently.

Well last weekend there were quite a few of us at a dirt dragstrip in three rivers, Mi. Lots of bikes there, and more 500cc 2 strokes there than iv'e ever seen in one place in my life. These bikes typically had out frame exhausts, and +8+10 in swingarms on them. Let me just say OMG!!!!!!!!!! These bikes are out of control. These riders are by no means rookies, and keeping them going straight and on the ground seemed virtually impossible. The only bike that had a shot at these big kx and cr's was a KTM SX540. With engine work, +8 arm and a great rider. Those 540's do rip, but a 450, no matter what make, will get smoked in a straight line. 2 strokes took the top 2 classes, and KX's at that.

There is either something wrong with the bike or rider if that is the case.

Meh, think what ya want, i see them everyday, SMR is supermoto, and i am talking bikes, not quads or anything else, a worked 560ktm will Absolutely Inilate a 250/500 on any sort of track with a pro rider,,, I like riding the big 2 strokes too, Just saying, they ain't got Nothin on the new Big bore 4 strokes.

the 500 is too big/heavy to really get serious with track riding. that, and it has way too much power for such a small area. the 500 was never meant for MX/SX. it is a desert racer and dune machine. go take that 500 and that 450 to the dunes and see who beats what..........the 500 is meant to haul ass for extended periods and to hill climb, not accelerate, brake, accelerate, brake..........

put the 500 into a 250/450frame and now you have a much better bike for MX, but it is still way to much HP for such enclosed riding.

In supermoto, a 500 is too much. A 450 is almost the perfect machine for supermoto. It is not that the 450 is faster, or more powerful, it that the engine is more tractable. That is why 250F's have almost the same lap times on a lot of tracks, corner speed, and smooth power delivery.

I remember Don Canet (cycle world) running a cr500 motard in the 600cc supersport races circa 1996-1997, doing pretty damn well. They can be ridden fast by a guy that can ride.

If you have ever slung a leg over a properly tuned 500 (75-80 hp) there is no question which one has more power, or is a faster bike.

Now if were just talking lap times a guage of a bikes power. than I guess a 125 is a more powerful bike than the mighty 450's on many mx tracks......

Like i said, just speaking from experiance, i help build and raced (supermoto/road) a Aluminum frame cr500, It did not to bad, But it was hard To keep a piston in the thing , it didnt like sustaind High rpms all day,,, Then sleaves started cracking, clutch's where another big commidity, Everyone here runs the big 4 stroke now, i was out on a 75+hp Ktm 560, that has got some nuts,,,,,lol

[fabiodriven]

Sorry, there's no way a 450 4 stroker is going to keep up with a 500 2 stroke. It ain't gonna happen.

[Louis Mielke]

I wouldn't say absolutely no way at all. I WILL say that they'll spend alot of freakin money.

Once again, depends on the race, in a straight line, doubtful the 4 stroke will hang. On the mx track. different story.

over here in europe we have an engine builder that makes 700cc 2strokes.
i believe he is from switserland.
Those engines are used for sidecar MX.
But imagine such an engine in a quad or bike frame
that would houl some ass.
