    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.

    No more overheating!
    Not my first CV4 radiator cap so I knew it would do the trick.
    I ride in the hot Australian outback where its pretty much 100 degrees Fahrenheit every day.
    I ride in a MX track in a sandy river bed (dry most years). The original cap would release the coolant when/if the bike stops suddenly (fall/stall) or just stopping after a few laps on the track. To avoid this, I would have a light run on the side road to allow maximum ventilation and low effort for the engine to cool down - this happens no more with the CV4 as it holds the pressure higher than original caps!

    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.
