1. Best oil I've used
Bought a 2021 GSX-R1000 at 500 mile break-in I put Ecstar in it. It was hard to find neutral when parking it and clunky shifting. So at 1000 miles it got another oilchange and it was the Motul 10w-40. Made a huge difference in the shifting and finding neutral so now at 4000 miles it's going right back in my bike. Oil is not just oil or name brand.
