Product Description
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.

Delivers Confidence in Clutch Feel: AMSOIL Synthetic Dirt Bike Oil’s superior friction-durability properties help minimize clutch slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when maneuvering around obstacles on the trail. In an extreme simulated-start test, AMSOIL Synthetic Dirt Bike Oil continued to deliver consistent clutch feel following 32 simulated race starts, while a leading original equipment manufacturer (OEM)-branded oil demonstrated inconsistent clutch-lever action and poor clutch feel after 16 starts.

The clutch plates lubricated with AMSOIL Synthetic Dirt Bike Oil remained clean and in good overall condition, while the plates using the OEM oil revealed discoloration and wear. AMSOIL Synthetic Dirt Bike Oil’s superior performance helps instill in riders the confidence that their bikes will perform consistently in all types of riding conditions.

Protects Against Wear
AMSOIL Synthetic Dirt Bike Oil withstands high-rpm operation, extreme heat and mechanical shear. Its synthetic base oils naturally resist viscosity loss and provide a protective film against wear to gears, bearings and pistons. Its anti-wear additives provide an extra measure of protection, promoting long component life to help riders get the most out of their bikes.

• Delivers confidence in clutch feel
• Superior protection against gear, bearing & piston wear
• Maximizes horsepower
• Helps extend clutch life

RACING IS RESEARCH™
AMSOIL Synthetic Dirt Bike Oil underwent extensive on-track testing in the bikes of AMSOIL-sponsored professional riders on the GEICO/AMSOIL/Honda Factory Connection and Team Babbitt's racing teams. A combination of racer feedback and lab testing allowed AMSOIL to fine-tune AMSOIL Synthetic Dirt Bike Oil for outstanding wear protection and consistent clutch feel — benefits riders demand.

SERVICE LIFE
AMSOIL Synthetic Dirt Bike Oil should be changed according to the vehicle manufacturer's recommendations.

Best oil you can buy

As most of you already know, Amsoil is the best lubrication money can buy. For my high-performance KTM Superduke 1290R motorcycle, the choice was obvious. Gained 1-2 mpg after install and the peace of mind knowing this oil meets all specifications for my ride are all I need to push this beast to redline over and over again. I use Amsoil lubricants in every vehicle I own. Wife's Lexus IS350, my Land Rover Discovery, lawn tractor, chainsaw, Yamaha scooter

Great product

I use the 10w 50 in my 2015 Ktm 250 xcw. I have no problems with it and works great. It works great with my Rekluse clutch set up. It has stood up the rigors of all my 2 hour hare scrambles so I will continue to use it.

Superior Oil

I use this oil in my 2016 Kawasaki KX 450 and it outperforms all others I've used. I can feel the bike running cooler and the oil lasts longer than other synthetics I've used. Very happy and will use Amsoil for years to come.

I won't purchase anything else.

I use Amsoil Dirt Bike oils in all the dirt bikes I've owned. I race off road XC hare scrambles which generate a lot of heat in today's race 4 striokes and Amsoil gives me 100% piece of mind.

Performance Plus

The KLR 650 came alive after I put this in it. I had to clutch it to pull the front wheel. Now I just big on the gas and it will pull it freely. Seems like tons more torque and smoother engine performance. The KTM is already a beast and this made it into the Demon on steroids.

Best dirt bike oil on the market

I use the 10w 50 synthetic dirt bike oil in my KTM 350 SXF race bike. I have a rekluse clutch and with this oil, I can start the bike in second gear. With oils that I've used in the past, I was not able to start the bike in gear. In addition, I have a full season of two-hour woods endurance races on this engine with no sign of wear at all. I have friends with the same bike that use competitors oil that have already needed to rebuild both top and bottom ends. In my opinion, Amsoil 10W-50 dirt bike oil is the absolute best on the market!

Without question the best product out there.

You have won my trust. Amsoil products are my default. I maintain my rigs, but run them hard. Sold my last truck at 275000 miles,wish I had kept it!
