    Nothing better

    I have ridden my 450x all over the country and have had some pretty hard crashes and these have held up great. I bought mine years ago direct and now see RM finally have them available. You can't tell from the picture but they create a triangle of support that will withstand anything short of running your bike off a cliff. They are all one solid piece and not pieced together like the other brands. You do have to trim your plastic a little to get them to fit properly. But nothing a razor knife can't handle.

    Easy to install

    Installation for my husband only took about 25 minutes, he said having an IMS 6.6 gallon gas tank helped a little but having smaller arms, hands, and tools helped the most :) He can't wait to go for a ride, did a few test starts to burp the coolant system of air and also check for leaks, so far all is well. Went with the "Hammer-tone" color to match the 99 engine, we don't need the extra "bling and attention" brought to our moto by having bright or off colors on expensive aftermarket parts :)

  • CV4 High Pressure Radiator Cap

    CV4 High Pressure Radiator Cap

    ROBERT in FL


    450's tend to run hot, especially on trails. The CV4 cap is cheap protection against a boil over. Highly recommend.
