Special Notes:

  • Does not fit KTM's.
    The Tusk High Pressure Radiator Cap is the simplest and most inexpensive way to reduce your motorcycle or ATV from boiling over. The Tusk High Pressure Radiator cap raises your cooling system’s maximum operating pressure and therefore raises the boiling point of your coolant. This is a perfect upgrade for most motorcycle and ATV radiators with stock 1.1 caps.
  • Higher pressure radiator cap increases the boiling point of your coolant to reduce boil over problems on your motorcycle or ATV.
  • Raises the boiling point by 25 degrees when going from a stock 1.1 kg/cm2 (15.7 psi) radiator cap to the Tusk 1.6 kg/cm2 (22.8 psi) radiator cap.
  • Perfect for 4-stroke and 2-stroke motorcycles, ATV’s, and UTV’s.
  • Universal fit for most machines.
  • Does not fit KTM's.

Works great

Comments On Mar 23, 2015:This has definitely reduced boil overs, I still managed to boil over once so then I replaced my coolant with Engine ICE and zero problems - Note: I'm in Phoenix and ride year round.

It's Workin'

Comments On Mar 04, 2015:Seals tight, and does it's job. All at a real price. No overflow, no leaks, cool down seems quicker, but other factors like air temp may skew that a bit. Over all I'm very happy. Usual result of buying Tusk stuff.

as advertised.. legit. great item.

Comments On Feb 24, 2015:just got this today and bench tested it with my radiator cap tester. 24psi before relieving pressure (a pound above its rating), NICE! Installed on the bike and ran on the stand for a while...no coolant puke. i got this paired with some fatty radiators and some engine ice in hopes of no coolant lost during trail floggings on the diminutive 250f. We will see how it does after some hard trail miles. Happy camper.. great item priced right! thanks RM for another dandy.
