Specially formulated for extreme transmission performance for riders who prefer a dedicated transmission fluid instead of a multi-purpose motor oil.
Grabbing the holeshot in a race or maneuvering around obstacles on the trail requires a transmission fluid that doesn't slip or grab.
AMSOIL Synthetic Dirt Bike Transmission Fluid is specifically formulated to provide consistent clutch feel, delivering riders confidence their clutch will respond the way they want. It also guards against gear and clutch wear so enthusiasts can spend more time riding and less performing maintenance. AMSOIL Synthetic Dirt Bike Transmission Fluid is a cost-effective insurance against premature component wear.
Package sizes include:
1-Quart Bottle
Case of 12 quarts
Recommended for use in two and four-stroke dirt bikes that use a separate sump, including those made by Honda*, Yamaha*, Kawasaki*, Suzuki*, Husqvarna* and KTM*.
• Delivers confident clutch feel
• Protects against gear and clutch wear
AMSOIL Synthetic Dirt Bike Transmission Fluid's superior friction-durability properties help minimize clutch slippage, providing riders consistent clutch feel during takeoffs or when navigating obstacles on the trail. It's formulated with a lower viscosity than a 40-weight motor oil, delivering more aggressive clutch feel. Its superior performance helps instill in riders the confidence that
their bikes will perform consistently in all types of riding conditions.
AMSOIL INC., the premier manufacturer of synthetic motorcycle lubricants, focuses on improving lubricant performance so riders can focus on improving their performance on the trail or the track. That's why AMSOIL is the Official Oil of Monster Energy Supercross, AMSOIL Arenacross, AMSOIL GNCC and the AMA Amateur Nationals.
The intense environment inside a dirt bike transmission can shear lubricants, leading to viscosity loss. A lubricant that has fallen out of its intended viscosity range can fail to develop a strong fluid film between parts, leading to wear. AMSOIL Synthetic Dirt Bike Transmission Fluid's high-quality synthetic base oils withstands viscosity loss due to shear. It delivers excellent wear protection for gears and clutch plates, helping riders get the most out of their bikes.

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 drive my dad crazy because I am hard on the clutch, but since he has started using Amsoil I do not burn out my clutch anymore.

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!!

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.

Does what it says it does extremely well. Impressive!!
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.
