    Must have!
    This is a must, my 2020 crf450rwe came with a 1.1 cap, if you do a lot of long rides in desert you might want to change to a 2.0 cap. It’s worth the money then overheating your bike!

    Does it's job.
    It is a radiator cap. It holds fluid in and relives pressure. It does its job, what is not to like? Well the price is a tad high but atypical for motorcycle parts. 4 stars instead of 5 because it is expensive for what it is.

    Very good product
    So far so good! I ride very technical hard Enduro terrain and my bike was steaming over a bit until I put this cap on I haven't steamed it yet thus far. Good price easy fix! I would recommend this if you are having steaming over problems when clutching the bike alot at low speeds.

    Is a 1.4 bar radiator cap to much pressure for a 09 kx250f?
    Tad D on Oct 9, 2017
    BEST ANSWER: No. I run a 2.1 on my 450 that I use in Florida/Georgia for 2-hr hare scrambles and 4-5 hour ensuros. The key to using a higher pressure cap is ensuring that you use the recomended coolant type in the system and not aftermarket "super" coolant without the proper lubricant additives to condition the seals. I have fellow riders on 250's using the 1.8 bar caps with much success. I hope this helps.
    Why do I need this mule part?
    A shopper on Aug 25, 2016
    BEST ANSWER: This high pressure radiator cap raises the boiling point of the coolant in your machine. Therefore, you can run it harder and longer with less risk of boiling it over.
    which bar pressure would be best for my 06 crf250r? will the stock hoses hold up to the 2.0 bar until I can get stronger hoses?
    kohl g on Jun 17, 2019
    BEST ANSWER: We run these 2.0 bars on all of our bikes. The stock hose will be fine assuming they have no damage to them.
    what is the difference between 1 bar and 2 bar ? 06 yz250
    Dominick J on Dec 12, 2019
    BEST ANSWER: A bar is equal to 14.5 pounds of pressure per square inch. By increasing the pressure in the radiator you will raise the boiling point of your coolant. The cap is your pressure relief valve that lets the hot fluids flow to the reserve tank without letting air into the system.
