As I've said for years, everything from about 1992-on is every bit as capable as the rider is of winning. The biggest advances are not with the engines, but suspensions and geometry, but an older bike is perfectly capable if you put in the effort and do your part.
Motocross technology was way ahead of the times, snowmobiles in comparison back in 1992 were really primitive and had no suspension, they have finally caught up now since 2016 or so.
Hey mate I'll be buying a new motor for my 99, old owner spat chain and cracked the casing, still runs and rides no leaks. I'll be doing it up really mint
I'm not a mechanic, just saying....but I have a question. If you took two identical "modern" engines (i.e. 2023 yz250) for the purpose of comparing. . Could you convert one to be air cooled (bare with me now!) Cast a cylinder and head with cooling fins, then put them back in the frames. On the air cooled bike strip the radiators and all un needed parts. And then compare them in a few laps to see if the weight of a cooling systems v/s the performance....I dont know if this is making sense , but I've always thought that relatively short motors, I bet the air cooling would be more than sufficient and make for a lighter faster bike. Anyway, just a thought...what do you think?
@@robertbradley1133 thanks robert! So do ya think losing that 8% bit being lighter without a liquid cooling system and a gallon or so of antifreeze would make the air cooled bike "competitive" with the water cooled bike? I know the longer air cooled bikes run they lose some horse power. But I really believe that for no longer than a moto is that it really wouldnt matter. And with the improved handling of hav ing a lighter bike...I just know it would be better
@@user-ko3vg7fc7o you'd lose more power than you gain by losing the weight difference. Also during a motocross race that barrel will get massively hot, if you don't believe me try touching it after a race! If you want a better power-to-weight ratio go on a diet.
@@user-ko3vg7fc7o I am afraid not as it’s about 8% across the board, so as well so as well the HP drop due to the expansion as other replies have stated your specific fuel consumption will go through the roof. So you would have to start off with more fuel in the tank than a liquid cooled bike, as the fuel is used up towards the end of the Moto your increasing the weight advantage would be diminished by poor engine performance due to heat buildup. Engineering is a big compromise and it’s a mater of balance to get the best possible overall performance. Thousands of hours of research will been put into designing these bikes. Racing machines in particular have bare minimum parts made from the lightest materials, the trick is to get the CofG in the correct place for the best overall packaging
I love seeing guys on 20 year old 2 strokes out there showing they can still be raced and be competitive.

Long live the ripping 2 strokes.
2 Strokes for life! Thanks for watching Kevin
Awesome stuff. Love them old 2 strokes. Bought a 2004 rm 85 to kick around on.
Big Love to you all across the pond
Thanks for watching Eric! It's really appreciated :-D
Great racing! So much better than watching four strokes!
Awesome thanks for posting this keep them coming roll on yz
Nice video Max, Tom really made his dad's yz fly, the bike must be very well set up and prepped to beat a 22 yz. Get him on the yzilla.
Could cut the music when there raceing
2 strokes the only music needed

Loved to see this he's needs to race that again deffo win 🏆
Great races! Great video man!
That was fun to watch
For when a video with a kawasaki kx 250 k5 (1993-2005)?
96 yz250 handled extremely well. Fix suspension engine was slow but that doesn't matter much unless your a pro
I had 96 bike was magic

Thanks Andrew, Appreciate your comment buddy.

Only if you run a slightly undersized piston, as the water-cooled barrel expands less than the air-cooled barrel when up to operating temperature.
Liquid cooled engines are 8% more efficient than air cooled

2 strokes have the power.
