Can an 85cc beat a 250cc in a RACE???

After riding with my son several times, I was seriously considering the possibility that is 2021 KTM 85SX had a higher top speed than my 2021 Kawasaki KX250X! We needed to test this!

Car enthusiasts say it all the time its a rather famous quote that i don't think anyone knows the source of. ( Its often more fun to drive a slow car fast than one that's meant to be fast. ) The original quote was in reference to cars like Mazda Miata's. where you can be squealing the tires around corners at WOT with a smile of your face not having to go deadly speeds in order to hit that limit. The same thing definitely applies to dirt bikes. Bombing around on a 110 with your buddies will put a bigger smile on your face than trying to push the limits of a 250. pushing the limits of a 250-450 takes actual work and focus. you can max out a 110 while laughing your ass off halfway distracted and intoxicated lol. not that im advising it.

[@SoSlo2]

I've always felt that the mini manufacturers are really missing out on the off-road market by not offering enduro models below the 125 2T class. KTM did offer an XC version years ago, but if I recall, it really wasn't that much different from the 85 and 105 SX minis. Based on the recent boom of single track, hard enduro and hare scramble popularity, I'd like to see them give the same treatment and R&D to a mini version as they do the bigger bikes: lower gearing, suspension, larger tank, kickstand, maybe even a different head and a flywheel weight. It could even be a really cool project to promote via the Gas Gas brand.

[@JETZcorp]

I'm impressed with thr KX. A kid on a modern 85 is a pretty wicked power to weight ratio.

[@trevor866]

More power that's wasted by how inefficient two strokes are. Might make more power on paper but that means nothing. On a track 4 strokes will eat 2 strokes. 85 is geared much shorter that also helps with acceleration. Its like the people who claim 250 2ts will out run a 450.

[@KTMsoldier1988]

@@trevor866 i have seen tons of videos of 2 strokes destroying 4 strokes on tracks in an open class event. If 2 strokes were allowed in pro motocross and supercross they would have a solid chance. It takes a rider that knows how to ride a 2 stroke! If 4 strokes are so efficient then why does it take 2X the cc's to produce the same horsepower. Love hearing guys say their 450 will beat your 250.

A little two-stroke 80 with a light Rider is as quick as any other bike out there but it starts to fall off about 60. A 125 2 stroke is another bike with 6 gears and it will start pulling away from the 80 at about 50 miles an hour top out about 70 and a 5-speed 250 2 stroke is about the same as the 125 it's just made for a bigger person

[@coleknight7572]

I think the 85 occasionally seems faster because it’s peak power is at a much lower rpm. The new 250s are making all their power at the tippy top. Meanwhile KTMs race 2 strokes make all their power a good 2 or 3 thousand below redline. So it’s easier for the 85 to see peak hp on the trails. But on a track or straight line there’s no comparison
