  • Tusk 1.6 High Pressure Radiator Cap

    Tusk 1.6 High Pressure Radiator Cap

    Tim in AZ

    Great inexpensive way to aid in boiling over

    Does it's job well. If you ride first gear super technical trails, this won't be enough. It definitely does help though. Also using aftermarket coolant will help as well. If that doesn't work, you'll need a fan.

    High pressure cap

    2 bar is the highest I've seen. Raises boiling temps quite a bit.

    Would not run a bike in the desert without a set. These have been on every bike I have owned. Saved me so many times I cant count. Don't wait to have damage and get stuck.

  • Watt-Man Thermo-Bob

    Watt-Man Thermo-Bob

    Michael in Colorado

    Well designed and made product

    I purchased one of these several years ago due to not being happy with how cool the motor in my KLR was staying when riding it. As I understand it, it doesn't break-in properly if it runs too cool, and it is certainly better for the engine to hold a good steady mid temperature. This little guy did the trick perfectly. I've heard that a KLR that runs at proper temp during break-in is less likely to burn oil. I don't know how true that is, but I can say that I have 27K miles on my 09' and I don't burn any oil, and the price of a thermo-bob is a lot less than replacing the head from running low on oil. Plus, the thermostat used in the thermo-bob costs about $12 to replace instead of the $40 that a stock thermostat costs. Overall, I rate this as THE mod to do for longevity on a KLR. (After the doo, of course :)

  • R&G Radiator Guard

    R&G Radiator Guard

    Matthew in FL

    Looks great!

    I love the look of the guard! Only issues are that the screw they sent to mount it was too short (luckily I have lots of screws) and lower mount is held on by a zip tie. Not a big deal but for $80 I would like more ingenuity...
