    Just curious if anyone has opinions or thoughts about the 650GS for fire roads and gravel roads? Will the rims be ok for that sort of riding?

    The great state of confusion
    As far as I know we have no first-hand reports (good or bad) on the 658 cast rims.

    While they are cast rims, they look more beefy than many I have seen. Also, apparently the 800 spoked rims aren't really as beefy as you might suspect...

    See the pictures at the bottom of this page:

    So ... you might buy an 800 and STILL decide the rims are not "fit for purpose" ? :huh

    Been riding mine on fire roads. No problems with the rims. Tire are a different story. The stock ones are fine for normal travel but if you plan on more aggressive riding especially on loose dirt/gravel knobbies like the TKC would be better.

    Chatting about this on another thread. Blackie, what do you think about throwing some X Country rims and knobbies on the 650 for a little more serious dirt riding? Not motocross, but not groomed dirt roads either.

    Yeah the numbers look about right, just wondering about the other stuff like brake rotor, sprocket mounts etc if those will fit too.

    I am seriously considering the 650 due to the fact that I "fit" better on it. I broke right leg and it is easier to throw my leg over the 650 due to the fact that is a bit lower. My only concern is that I want to go to South American on it and wonder about the cast wheels. I really don't think that I am going to "bash" it over big rocks/trees/and truck parts if I can help it.
    I appreciate any "insights" you might offer about the cast wheels. I realize that if one hits anything big enough it will take out either type of wheel.

    Again...thanks for you comments.

    Cast rims -> Tubeless tyres -> easier to repair punctures on the side of the road :1drink

    I think that as long as you maintain good pressure in the tires (over 30 psi) the rims will be ok for almost anything you would attempt on the 650. I went uphill on two long runs of concrete steps last week and the rims survived. Maybe not much of a test as hitting a pothole at over 60 but just don't think that there's much to worry about if you keep the psi up.

    Don't you usually air down for off-road?

    When are you planning on modding your 650 for a trials bike? :D I don't have any stair climbing skillz!:bow
