guy53 Posted November 18, 2018 Report Share Posted November 18, 2018 I know it's been ask about a hundred time, but the I don't have a lot of choice here. I recently bought a lightly use Sherco St 250 2015, I really like the feel of the clutch. Now I have to change the oil in the gear box, unfortunately, I don't know and can't find what is in the gearbox. I have avalable Motul Gear 300 SAE75W90 100% synt oil. Any comments on that?

lineaway Posted November 18, 2018 Report Share Posted November 18, 2018 That is an oil for a car gear box. Do not use. Quote Link to comment Share on other sites More sharing options...
section swept Posted November 18, 2018 Report Share Posted November 18, 2018 The Sherco workshop manuals are all available on line just google them. Why dont people use this facility. Your bike should use a good quality 10w 40 engine oil. 2 Quote Link to comment Share on other sites More sharing options...

Yes automotive gearbox oil is out don't use that. I thought it was there motorcycle oil... Turns out thats "Motul's Transoil Expert Gearbox Oil - 10W40" Witch would be fine. Deleted my first post.

misscrabstick Posted November 19, 2018 Report Share Posted November 19, 2018 I am really into Putoline nano on my Beta, I have messed about trying a few, this seems the best so far. Quote Link to comment Share on other sites More sharing options...
guy53 Posted November 19, 2018 Author Report Share Posted November 19, 2018 I was surprise to hear that the Motul in question was automotive oil as the dealer is not into auto., I checked the Motul site and they list the Gear 300 SAE75W90 100% synt oil as auto and moto oil, and gear oil viscosity isn't '' calculated '' the same way. That's why I asked, I'm sorry if I had some people offended by my question. Guy Quote Link to comment Share on other sites More sharing options...
jonnyc21 Posted November 20, 2018 Report Share Posted November 20, 2018 (edited) No offence at all with your question. lineaway was just trying to keep me from accidentally giving bad advice. The trick here is that some motorcycles like BMW shaft drive might use that in the rear gear/hub but it wouldn't be used in the engine, so yes motorcycle approved but not inside the engine. So I would look for something that is specified as for a 2T motorcycle engine and would also be good if it states wet clutch.

Guy i think you can put in your bike, it's an high protection gear oil, i have used in Fantic section the Motul HD 80/90 high viscosity oil (for hypoid) and it was the only oil that allow us to run without slepper cluthc problems. Yes high viscosity oil have a problem sometime in trial gearbox, the disc do not detached as well as a low viscosity oil, expecially at low temperature sorry for my english ?
