125-200cc Transmission Oil - What to use? How much?

This may be a stupid question - but I'm only familiar with Japanese bikes. I just got a Husky and want to change the oil, and I don't currently have a service manual to look this up so...

Can I use BelRay Transmission Oil - 80W in my 2012 Husky CR 125? Or should I use some other kind of oil? And how much should I use?

Ty races the MY12 CR125 and we use both Amsoil and M1 0W40 in his race bike.

Is that automobile engine oil?

Two strokes arent as anal as 4s.
Any quality gear oil will work,IMHO.
Rotella has always done me right.Or ive run Motrex,and Honda with good results.

The manual calls for 10W-40 oil. I use Motorex which has been working great:

The 125's oil capacity is 0.8 litres, or 0.85 US quarts.

I've ran 10w40 and Atf with no problems. Both seem to shift the same and have a bit of clutch drag

You will have less clutch drag from the start using the 0W40. Auto oil - The Amsoil is not, but the M1 is. I can place a motorcycle sticker on th M1 bottle if it makes you sleep better. Motorex also makes 0W40.

I've always stuck with 80W motorcycle gear oils because I've read that there are detergents and additives in the 10W40 automobile engine oil that, supposedly, aren't to be used in a wet clutch like on our dirt bikes. Then again - ive read that a lot of people use automobile engine oil in their bikes without any issues - which is the case for you.

That doesn't mean that ALL 10W40 oil is an automobile oil, however. Hence the question.

Sounds like I'll be fine with 80W gear oil that I typically use. So now the question is - how much do I put in?

If auto engine oil is JASO rated it is ok in a wet clutch. I use Rotella 15w40. Rotella 15w40 is equal to approx 50w gear oil.

Perfect - thanks man

If the bottle says "energy conserving" don't use it. That's the stuff that will make your clutch go all funky. My CR had Belray gear save in it when I bought it. I found th shifting clunky and difficult. Didn't know if it was the bike or the oil, so I used a 15W40 diesel oil similar to Rotella, and the shifting got much better. Some people prefer gear saver, but I didn't like it.

After Tinken has been beating the M1 0-40 drum , I tried it and it worked great. I have switched my bikes over to it and it greatly improved starting and shifting .

This Valvoline Synthetic (10w40) 4-Stroke bike oil works great on my '08 WR250. Helps a ton with clutch drag.
