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 caps.
  • Higher pressure radiator cap increases the boiling point of your coolant to reduce boil over problems on your motorcycle or ATV.
  • Perfect for 4-stroke and 2-stroke motorcycles, ATV’s, and UTV’s.

  • 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.

Works Great
My new CRF 450R was boiling over every ride, no matter if I was on a fast mx track, sand or single track. I purchased the Tusk High Pressure Radiator Cap and a set of high pressure silicone radiator hoses and the boiling over has stopped. The weather has cooled down a little, but it has definitely helped.

Great replacement
I was experiencing overheating on my new Honda Pioneer 1000-5 After performing a few diagnostic tests I found that the factory cap was not holding steady pressure so I replaced it with this one with a slightly higher pressure rating and have never had another problem

Does the job
Not much to say. Stays on. No holes in it. No boil-overs. I think that's a win for radiator caps.

I have a Kawasaki ER6N 2009. I changed out its oem radiator and installed a new one, but my old cap is to short to create a seal. I need at least a inch long neck on the cap. What product would work?
A shopper on Oct 25, 2016
BEST ANSWER: It's the same dimensions as the oem cap so I don't think it will work for what you're looking for.
Can I use this cap on 2014 Honda TRX450R with Honda hp type 2 blue coolant?
