Beta Riders Club Discussion Forum

Was happy to see a bottle of Motul trans oil came with the new bike when I opened the crate
I've used the stuff for years and will continue to

I have always used ATF in previous 2 strokes, and never had an issue.

Beta service manual is stating liqui Moly racing 10W40 for the 300 gear box
anyone using this? or have used it?

I have had very good results with the Honda HP Trans Oil SAE 80w/85W and I am hard on the clutch.

I use Delo 400 mainly because I find it works really well, my clutch is super nice but also it's great for getting into arguments on the internet.

That's the main goal of an oil thread isn't it?

Some of the things you get told: The proprietor of a motorcycle repair and tyre shop who I consider a friend berated me for not using a specific 2 stroke gear box oil. It was Motul 5100 engine oil versus 5100 trans oil.

His reasoning was that a 4T oil would ruin my crank.

I wondered how it was going to get in there.

I said my understanding, and that's all that is, is that the trans oil 5100 doesn't have the stuff it doesn't need to be in the top of an engine.

The fact that the trans oil 5100 is a few cents cheaper might bear this out.

In the 1970's ( this was all trees then, no buildings ) the handbook told you to run 10w or sometimes 10W30 motor oil in the trans. My IT175F manual told me to run 10W motor oil in the forks. Guys started running ATF which is about 7.5W ( as far as I know ) in their forks and 2T trans. It worked well.

My point is, I am not sure of any ground braking technological ( can't believe I spelled that correctly, WIN!! ) improvements to the 2T trans. Okay the fibre isn't whale skin any more or something but it's still the same mechanically.

My favourite is: Why do you use a diesel engine oil in your trans, you should use a motorcycle pacific ( sic ) trans oil because your bike is toadally gonna blow up mang.

It's good stuff, that's why. My clutch doesn't slip ever and I can go over to my bike stone cold in first gear, pull in the clutch and push it.

If you are happy to use Motul ( I never had a problem with it ) or any other Motorcycle oil please continue.

If you start using Delo or any other diesel oil then do it because you looked into it, maybe spent an afternoon or 3 with a cup of something learning a bit about oil, it's make up and what it can and can't do.

Not because I said so.

Peace

Riding a 2018 Beta Xtrainer. Low speed technical rocky rooty steep 1 and 2nd occasionally 3rd gear riding. Air temps 90-95 high humidity. Hawaii.
I recently "Upgraded" from the regular Rotella Diesel oil which I have been running for 2 years to their Synthetic. Not sure yet if it is a coincidence but I am having some trouble with overheating since doing so. I also at about the same time installed a Rekluse radius CX clutch which I don't bog or run it in too high a gear so I don't believe I am creating more heat slipping the clutch...unless the synthetic oil is causing slipping.?
I spoke with my very knowledgeable mechanic and he said he recommends that I go away from synthetic oils for the trans/clutch. Wondering if you or anyone on here had an opinion on synthetic oils for transmissions with a wet clutch and if there is a problem.
