Schaeffer Manufacturing Co. 024030-012S Extreme Performance V-Twin Primary Lube, 1-Quart Bottle

I installed this oil in the primary of a 2004 Harley soft tail. the bike shifts so smooth. I will be installing it in my 2023 Tri- Glide also.

Stopped my clutch from slipping after using Mobile 1 but this made it stop and go back to normal.

Awesome

Started using Schaeffer products after George Bryce recommended it. He owns Star Racing and uses this product along with engine oil. He showed a break down of a race engine he built that had very minimal wear and tear. I used it in my built 107 and loved it. Now I use it in my 2020 RGS. Tired of the clunking noise. Change all your fluids to Schaeffer and you won’t regret it.

I use in my race bike and started in my regular bike and it helps !

I usually run the Harley primary fluid. But had a quart of Mobil 1 10-40 metric oil that was compatible. I hated it. Bought this cause their the best and it was cheap. I love it. Smooth shifting and quiter.

Night and day difference in my sportster.

Do your research, this company has been out there for lots of years in St. Louis Missouri.You will definitely pay more for supreme quality.
