  • Maxima Chain Wax


    Not for me.

    Not a fan. Once dry, this chain wax is super hard to remove. Sure, it gathers less dirt, but your chain will still get dirty and will have to be cleaned before you can lube it again - that is when things get bad. I went back to using WD-40 after every ride - on both my street bikes and my dirt bikes.

  • Yamalube 2-R

    Clinton in CO

    2R oil just as good as the "expensive stuff"

    With the work done to my engine, I was told I had to run VP 2t Premix gas. I was hesitant to try even running pump gas, and premix. I was in a pinch and bought octane booster, yamalube 2R 2 stroke oil, and some premium non ethanol gasoline. The bike ran better on that, than with the VP fuel. I had less oil not being burned, less plug fouling, and way better trail performance. Definitely will buy this oil more. Also this oil performed just as good as the more expensive Motorex oil brands.

  • Yamalube 2-S

    Tony in CA

    Rocky Mtn Has Stock

    I have two PW50’s for the kids and they burn through the Yamalube. It works perfectly for the injector. A lot of stores in my area are out of Yamalube but Rocky Mountain had what I needed.
