500 2 strokes always were slower then 250 2 strokes!!

[wintrader]

I do not get it, in the old days 250 2 strokes were always faster then the 500 2 strokes. So why do we think that it is not fair to race a 250 2 stroke against 450 4 strokes. Why should all of a sudden a 450 2 stroke be faster then a 450 4 stroke?

What's a 450 2t?I think you have a typo or two in there

[SachsGS]

Over the decades the tracks have changed.The Supercross influence relegated 500s to the MX museum.The key thing with the 4S's is traction and I think this is why in certain situations 250 4S's are turning the fastest lap times. All the power in the world will not do you any good if you can't put it to the ground.

I suspect  when Mitch Payton ported that WR300 cylinder that is what he was looking for.

I know tracks changed over time but in the old days with the old tracks 500 also were not able to lap faster then 250 2 strokes. In heavy loomy sandtracks 250 4 strokes normally much faster then 450's.

Back when those beastly 500cc 2-strokes were racing they did have more power than the 250 2-strokes of that time but the 250's were alot lighter & easier to ride therefore they turned quicker lap times.

Not lighter!!! I rode a maico 250 and that is abouty the same bike as a maico 440 at that time just different engine. Maybe one or kg lighter not more. It is just the bulky power what is in the way.  The open class bike were not lighter!!! Also drove a 1982 maico and that was a handable 500 and that was so good about that bike. it certainly was not the strongest openclass bike. The whole packages was just good. M ost of the openclass bikes were just to difficult to ride and wheelied to much.

If youve ever raced a CR 500 or any other brand of big bore 2stroke you will understand why its easier to go faster on a 250 2t.
What a handful!!

Absolutely right!!!!

I remember back in the day 125's turning faster lap times than 250's. Slightly lighter bike, lighter rider, different lines due to different power and handling characteristics can all add up to faster lap times... but there's still something about a big bore 2 stroke, bring back the open class!

Thats what i say riffraff, if they started making them again it might stop people trying to sell there 2000 model CR 500's for $8000!!(thats Aus dollars by the way) its gettin out of hand i tell ya............

[MCGRIDDLE_321]

i could be wrong about this, but wasnt it last year ama passed a rule stating that the 450 class was now called a open class?? if it is then there is no reason why you cant ride one in there.

[riffraff]

According to Section 1.4 para.B they have 2 classes, 250 and open

Yes lighter.Depending on year,make ,model etc, a 125 is about 20lbs lighter than a 250 which is about 20 lbs lighter than a 500-more or less anyway.Often a larger displacement has the chassis beefed up somewhat.Disregarding that,a bigger engine takes more metal-and that weighs more-oddly enough.

Not so much weight difference!

[ford832]

Don't believe everything you read at the brochure.Also,when KTM brought out their first 250f EXC it was virtually the same weight as the 400-because it was a sleeved down 400-later models were lighter.I stand by my figures-they're accurate.
