Good Quality and it takes the guessing out of the equation
You only know how good oil is when you drain it after use. The longest I’ve gone is 35K. The color was good, a little darker. The smell was good, not burned. And the viscosity was still good. Clutch still going strong, and chains are still quiet.

Nice quality
Great lubicrent works perfectly in my bike for what I needed it to do perfect. Weight, it definitely makes the engine run a lot smoother, and it is a very good value for the money.I would highly recommend this product

Smooth..
This stuff is legit. I recently had a clutch cable break. I was running formula+ in the primary. I installed this when I installed the new cable as the clutch was slipping prior. Shifting into first is smooth, and primary noise is minimal at idle. So far it’s doing great. Maybe 200ish miles.

The best oil period
Whether you own a sport bike or harley davidson Lucas is the best. My Vtwin air cooled runs way smoother and quieter. Very noticeable. If you love your bike...then there is no substitute. Think about putting HD oil same viscosity in all 3 engine components? That doesn't make sense. Use the 3 different Lucas for all 3 application. Do NoT listen to the fat HD guy

I've long been a fan of Lucas products. This primary oil seems to work great and hasn't caused any shifting or noise issues.
