use Amsoil in two different Harley Davidson motorcycles and had good luck with it

wouldn't use anything else hands down the beat u can get

The best product I ever used

Can tell noticable temperature reduction in my 110 Harley davidson motor.

I have a Harley low rider s with the 110ci and I run the v twin oil in my engine, the primary oil in the primary. And the severe gear 75 90 in my tranny. Runs like a dream, only complaint is the tranny fluid is next to impossible to see on the dip stick so it's hard to tell the fluid level when filling. Wish it had a dye in it or something

I've run Amsoil for as long as I have rode Harley's and this is my third one. Not one minutes trouble and I have rode in some of hot weather it was so hot a friends bike shut down and mine never skipped a beat. Now my friend runs Amsoil as well

Use it in both my 02 Ultra and 05 Heritage knowing its going to keep them lubricated and running through the long haul.

I use it in my bike best oil ever. Best for tranny and primary products love it.

i have a '98 Ultra Classic that was getting harder to shift. I changed out the clutch plates with a set of Barnett HP plates. I also changed the primary oil out to the Amsoil 60w synthetic. Wow what a difference. It has never shifted so well even when new. I also changed the engine oil to the same 60w. Contrary to beliefs, it is not to heavy during the Virginia cold winters.

I switched to Amsoil's 20w-40 V-Twin formula a couple thousand miles ago in my '17 Indian Springfield, with the Thunderstroke 111ci. Right out of the gate I could feel a positive change in my bike....I could now find neutral easily! Other than that, time will tell. But just from that it shows my the internals are running smoothly. Also, some are scared to run "Full Synthetic" in their bikes, fearing clutch slippage. It's in both my wife's Chief and my Springfield. No slippage! There are no friction modifiers in this, so it's good to go for wet clutches. I will continue to use it.

I've been using AMSOIL products in my motorcycles for the lastest 20 years and could not be happier when doing motor work and seeing how good the products work.

I use Amsoil in my motorcycle and car. I believe in the product completely and I know my vehicle's engine just runs better.

Best oil and protection on the market 1ST in synthetics for a reason dont run anything else!!!!

Use Amsoil in motorcycle & truck. Excellent products

Great oils great service

I buy all three types oil, engine, transmission, and primary.

I'm a new user to Amsoil, but using it in a Tahoe, Harley, and an Indian Scout.

I've been using Amsoil since 1993 in my Harley's. This is the only oil that I know that helps cool the motor. Amsoil has never failed me and I will always use this oil, and only this oil my in HD motor, tranny & primary.

Did an oil change on my harley Davidson bike runs much smoother than the regular harley stuff they use definitely an awesome product

This is the ONLY oil I trust in my bike. I've tried other oils that don't deliver, including all versions of OEM oil. After countless hours in parade mode, AMSOIL quieted the motor & drivetrain better than OEM. I run 10k miles on AMSOIL w/very little noticeable wear on any component, which is evident by less steel debris caught by the oil plug magnets, compared to what I did see running OEM.
