The only Oil you should every use, EXCEEDS O.E Engine Oil specifications for higher performance, high compression four stroke technology. Superior wear resistance, your engine longevity and compression will outlast all expectations. I use it in all my engines, ATV's YAMAGA YZ, YFZ, HONDA Crf

Works well in all of our snow bikes, clutches work well. Shipping was fast.

Used it for my 250 xcf-w, clutch feels great. Gives me peace of mind knowing the engine is protected with such a quality product.

GREAT PRODUCT, TRY IT YOU WILL NEVER USE ANOTHER OIL. RECEIVED MY ORDER THE NEXT DAY.

My 2007 KLR 650 runs great with this oil and a hiflo filter from Amsoil

The clutch feel is amazing amsoil is the best out there all I will run in everything

I won’t install anything else in my son’s dirt bike. The best. Protection. Period.

Works great in the AZ heat!

The oil and lubricant I have used for my dirt bike and truck wouldn’t use any other oil

Bought as dealer recommended oil for Beta Evo 4t, 10W40 works great with clutch feel.

I wasn’t a huge believer of oil making a difference in my bike at first so I always ran just the manufacture oil. Then I started using the amsoil in my bike and it really made a difference the bike runs cleaner and is more responsive. I’m a firm believer in the amsoil after using it and how my bike preforms!

I have been using this oil for almost two years in an air cooled atv racing engine. We don’t always get a lot of cool down time between races while running multiple classes. This oil was the first amsoil product I used and has made me a believer. Thank you for an awesome product

I've been running AMSOIL in my current Motor Bikes since new, mostly because I didn't want to spend the $$$ on the brand KTM recommends. It costs me half as much using AMSOIL. I ride my bikes very hard, but I do change my oil regularly. I was about 20 hours overdue for a ring job on my dirt bike (KTM 350 EXC) when I finally tore it apart expecting normal wear, but to my surprise there was almost no wear!!!! The cams looked brand new, cylinder was in great shape, etc. Everything inside looked new. After seeing that I am completely sold on AMSOIL.

Little pricy but we'll worth the $. I ride my dirtbikes pretty hard and the hours add up quick. Sometimes they add up b4 you realize you were do for a change hours ago. But using good oil like AMZOIL you can get away with being a little over and not worry about damage to your engine.

My son races MX and SX on his KTM and Husqvarna 65's and 85 and this is the only oil I will use. I also use it in my KTM 250SXF with much better results than the recommended oil. On my son's main race bike, we have over 103hrs on the same clutch using this oil. This includes lots on gate drops and hole shots. We do change the oil every 4-5hrs because the bike only holds .5qts.

I’ve tried many different oils and amsoil is by far the best product I’ve come across minimal derbies after changes long intervals and excellent performance. Amsoil is #1!

Like each Amsoil product I have tried this really makes a difference in the performance of my bike. The engine is quieter and it shift smoother then any other oil I have tried. I use Amsoil in all of my motorcycle, lawn, and small engines.
