    Looking to get a set of these for the next time I change my tires. What is the size of the valve stem on the XB wheels?

    But I don't know what size I should get.

    11.3MM
    8.3MM

    Cheers!

    Be careful! Don't ride with them.

    Had some on my Uly and they disintegrated while riding! Luckily I didn't come off!

    agree with wally. 90 degree stems are generally used on small rims such as 10" and 12" scooter wheels. the reason being that the distance between the rim area and hub area is so small a 90 degree valve stem makes accessing the valve stem much easier. plus these wheels generally rotate at much lower speeds than motorcycle wheels due to the application.....even though their radius is much smaller.

    Wow...didn't realize this.

    Thanks for the heads up!!!

    Guess I'll just continue to deal with the OEM.

    Cheers Gents!

    Is that the adaptor that you screw onto the original valve ? I have to use one on the rear on my Uly. You can buy 90 degree valves that are one piece.
