I have used Bel-ray products since the 80’s and haven’t been let down. The Thumper Racing Synthetic oil works great and is affordable.

Can't tell a difference between this and the almost twice as expensive amsoil I've always used. This will be my oil from now on
I just started using this in my RM-Z250.
I use this is my 15 CRF250R, and is working great. No issues with bike, the jug has a built in spout in the lid which makes pouring into a funnel that much easier.
Great oil for a good price!
Great oil at a good price. Works great in my kx250f. I also use Bel Ray gear saver oil in my 2 stroke
One of the Best Oils you can use, also when I switched to a 4 stroke bike back in 05 I contacted BelRay and spoke with John. We went over the oils for my new bike as I was a 4 stroke virgin and since I have used BelRay ever since I was a kid I stick with it. They are spot on offer great sound advice and support. When we tore my engine down the first time ever the guys in the shop thought it had been torn down and all new internals. That was at the 9 year age of my bike.
