been looking for this vid for a while, it's nice to see a CR500 being ridden flat out in every gear, without certain death or injury!

Yeah the spanking big sportsbike's bit was pretty cool!

The two things i've noticed though were firstly how scary is the sound is of a CR500 being revved right out? it just sounds wrong, like it does when you hear a Harley Davidson or a VW beetle being revved into the redzone lol!

Secondly is holding a 500cc MX 2stroke engine at full throttle at high speeds for fairly long periods abusing it or even likely to cause engine damage? Some of the comments were basically saying that the guy was killing the motor by riding it like that on a big long track.

I would assume in an MX event that the throttle would be wide open not for very long and not at all unless the rider was a fearless big hard bastard that was having a bad day!

Very cool, 2-stoke supermotos are rare (well above 125's), always nice to see/hear one.

Nice, like the way he used all the track plus a bit more, good on the brakes as well.

My 690 can do 120 with standard gearing A lot of sumo's could it's just they are geared for tight tracks where acceleration is more important.

A big brembo or beringer set up on such a light bike will give you 1 finger stoppies no problem, especially when race spec sumo's are so light.

It's pretty well acepted and has been for years that a 450MX bike would be faster and better off road than a 500cc 2stroke.

On an SM track and especially the tighter ones the 450 should be much quicker too.

For top speed it depends on how they are geared, but with std engines id expect there not to be much in it. The 2stroke won't really overev and is all done before 6500rpm, so you need to gear it right, and getting tall enough gearing for 100mph+ seems to be difficult to find.

For drag racing and maybe beach racing the 500 should be quite alot faster than the 450's, but then i suppose a fair few 500's are tuned and im not so sure there is potential in a 450cc 4stroke for another 20bhp to be gained?

It does look to me that the CR500 in this vid is way ahead on braking performance too, and that it's limited gearing wise as expected on the straights.

What i would like to know is at what speed does say a 160bhp superbike weighing 170kg's start to really out accelerate a 60bhp 100kg bike?
