    So the new bikes all have 50 mm forks. Does just the increased size make them a better fork or is there new valving and internals too. In the past I have heard the 45mm were not very good stock so is the 50mm alot better?

    I think thew TXC 50mm forks are a lot better than the 45mm forks.

    Aside from internals improvements, in theory, a larger diameter tube can have a thinner wall thickness for the same or greater strength.
    So, there's a very good possibility that the 50mm forks are the same or similar weight, but far "stiffer" than the 45mm forks.

    Stiffer forks are less prone to seal leaks and tend to transmit more "feel" to the rider than smaller diameter, more flex prone forks... but much of that theoretical benefit would be under extreme conditions.

    I know... more useless information than you ever wanted to know. :oldman:

    Understand that the 08-09 TXC and TC 50mm forks are different (and better IMHO) than the TE and other 50mm forks.

    08-09 TXC/TC - the best
    other 50mm - real good
    45mm - workable

    Honestly they all need revalved to be great but the TXC 50mm have the more potential.

    Anyone here old enough to remember the 44mm Fox "Factory" Forks of the late 70s - early 80s?
    For the day, they were the state of the art - monsters of the fork world.

    Just reminiscing. :oldman:

    Nope... Fox Factory. With a complete CR250R conical wheel/brake assembly. Even had an air pressure control to adjust fork "ride height".

    Me and a buddy rode there from Cal for the Aspencade... back when it wasn't a Honda supported deal, but just a bunch of bikers havin' a good time gettin' our raccoon faces on.

    I just bought an 82' husky 430 cr with a Fox factory fork just a few hours ago. I'm taking accounting of what's on this bike and was just wondering what anyone knew about these. Who would know about servicing?..or anything about them?
