I have tried several transmission oil’s for my bike, some good some bad. so far Amsoil Dirt 80 is the best I have used when it comes to preventing slippage.

I use this in my KTM 300 and it works amazing!

Great oil, I can see the difference on my bike

Changed my sons Transmission oil with out him knowing to see if he noticed a difference. His words - “ Seems like my bike is shifting better today. “ Felt like the clutch didn’t slip as much on mine. Better engagement on take off. Good so far.

I run this in my son's yz65 at 40:1. My wife filled the bike twice with straight gas, and ran it. There has been no cylinder or piston damages.... i blame the oil

I put this in my son's KX85. Great stuff. I just split the cases yesterday. Everything on the transmission side looked great. The clutch plates were hardly wore. Everything stayed really well lubricated threw the process too. I will continue to use this product again and again.

The first thing I noticed was how smooth and easy the transmission shifted gears. That is after the bike is in motion and I'm accelerating through the gears. During acceleration when I shift gears the transmission is quieter and feels more like a dull thud instead of that metal to metal clank. Very smooth. It really makes me feel like my transmission is getting the best protection. I was so satisfied with the results I was convinced I need to try the newest transmission fluid for my Harley as well.

I change tranny oil on my 2 stroke dirtbike every 20 hours for routine maintenance, the oil is still fairly clean and could last another 10. Helps give the clutch a smoother feel as well, even the rough Hinsons.

Really love the clutch feels that this oil give to my bike but need to use it little more time to be sure that the quality is higher than the past oil I've used. Last oil change, the level was lower than the full quantity I've put in it after 6hours!! Need to see if it gonna repeat another time!! If yes probably look for something else. If any question you can contact me!!

Good oil. I really dont give anything a 5 star unless I am wowed somehow. This is oil, no fireworks need to be involved. :)

This is an amazing product and have been using them for years

I have 250 RMZ Suzuki that is not known for having a strong clutch. This oil made the clutch more precise and it had zero slippage.

I use this product in my 2 stroke & as a mechanic I can truly say it lives up to my expectations! Clutch is solid & great positive traction in the deep sand of FL!

I find heat is no issue using Amsoil Dirt Bike Transmission Oil. But the biggest improvement since my switch to the Amsoil is the better shifting I am getting. Missed gears are a thing of the past since I switched to the dirt bike tranny oil.
