I've been using this in my 01 KX 250 since I bought it in 2011. There have been no problems with this oil. I mix it at 40:1 with proper jetting 92 octane. No powervalve issues either, operates like it should.

H1-R Racing 100% Synthetic Ester 2T Engine Oil is the ultimate 2-stroke racing engine oil formulated for all power valve 2-stroke engines. Advanced 100% synthetic ester base oils cling to metal, preventing wear in all 2-stroke applications. Clean burning to prevent carbon build-up in combustion chambers and power valve mechanisms. H1-R keeps engines clean and responsive even under the most severe racing conditions. Not suitable for methanol fuel.
- Bel-Ray developed the H1R synthetic 2-stroke racing oil for race performance 2-stroke engines with a unique power valve formula.
- High-performance characteristics of the H1R synthetic oil continue to boost its unique anti-wear chemistry even at extreme RPM's.
- Improved power and throttle response is part of Bel-Ray's H1R power valve cleaner thanks to its ability to control deposits.

used for years at 40/1 versus stick 32/1 long engine life
New bottle has an overcomplicated cap - almost hate it
I have used all oils out there and this is the best by far. 40/1 in my cr250 and It burns perfect and makes no exhaust residue. Its red which helps to be able to see in your can that you have mixed it. It does need to be shook up very well in the can to mix with the gas but it never separates once mixed. It smells ok when burned but there's definitely better smelling mix out there.
I have used H1R for 10 years and have had no problems what so ever !
We use H1R mostly because the power valve on the YZ 125 doesn't get nearly as crusted up when we use it and makes cleaning the valve (still part of our regular prep) a quick/easy.
best oil i every used - burns real fast with almost no spooge
Works great! I will be buying again
idk i used it once and then my bike ran hot and blew my piston .....whichh would make me never buy it agian but my friends use it and love it so idk i guss it all depends
I would not use anything else!
I bought a 2002 cr125r with a frozen power valve... a 30yr Honda mechanic dealership owner told me to mix this stuff 40:1 with senoko supreme... less than a half tank the power valve freed its self and started operating... oh and its smells awesome... take the pipe off the head and its clean no carbon... great product im running it in my 2006 cr250r, ktm sx50, 1976 mr250.. anything 2 stroke power valve or not... I think this stuff lubes the internal better period... so long yamalubeR you were great for years.. but this new tech stuff took over....
Best oil you can mix with gas period. Belray all day. nuff said
We have definitely not regretted switching to Bel-Ray H1R. I really believe this is the best 2-stroke oil on the market. Our throttle response is noticeably better on our CX65 with the Bel-Ray over what we were using previsouly.
I have tried all oils from yamalube, golden spectrum, klotz, amsoil, maxima 927 and k2. Most of them made my power valve clog and drip on the side, i run 36:1. The belray is by far the best, no leak or bog. Recently did a topend job and didnt have to clean the powervalve. Yes it is expensive, but its worth the money and you can go a lot longer on top ends. I changed my top end at 60 hours and still had alot of time on it. I use all of belrays oils and they all work amazing never had a problem in any of my bikes transmissions. I will never stop using belray oils. I use it in both my 07 and 09 yz250s mod and stock. Thumbs up for two strokes.... Bbbbrrrraaapppp
Its no secret that Bel-Ray makes a great product. We are so glad we made the switch to H1R. Absolutely the best 2-Stroke mix we have used in our 3 years of racing.
This is the best 2-stroke oil we've found so far. A recent top-end rebuild on my son's KX-250 helped make the decision to use nothing but synthetic oil going forward. In our experience so far Belray H1R makes the bike run great, start well, and it really extends spark plug life. We mix it at 32:1 and there is not too much smoke after the engine is warm. Excellent oil!
This a great oil, you have less smoke & less plug fouling, you can also mix it at higher ratio for better protection.
when done shaking,shake it some more! great stuff but need to mix real good!
The oil that is contained within the engine on your KX250 would be the transmission oil. If you are looking for the oil that is used in the transmission, it would be Bel-Ray Gear Saver 80w Transmission Oil.
