  • Motion Pro Thumb Throttle Kit

    Motion Pro Thumb Throttle Kit

    Aaron in WA

    Good to Go

    Tors broke so decided to eliminate it. This kit works great and is easy to install. Only thing I’m not liking is how tight the throttle is. Might be how I routed it but not too sure.

  • Maxima Super M Injector Oil

    Maxima Super M Injector Oil

    Frank in NV

    Best 2-stroke injector oil out there.

    I have multiple 2-stroke motorcycles with injection units on them. This oil is, by far, the best injector oil I have used. Burns really clean and the color makes it easy to see in the lines. I recommend it!
