    Default xr100 crf100, which frame brace?

    I'm ordering a frame brace for my 2003 XR100, and I've heard mixed reviews of the BBR brace, and solid reviews for the Banke. But all the people who preferred the banke were flat trackers. What do you guys think is better? Stronger? I'm not going to be jumping 100 ft triples, but I'm a big guy, 260, and I don't want my frame to fold up.

    I've used both but, couldn't tell a diffrence. The BBR is aluminum so it has the advatage of weight. Also the BBr was designed for motocross. With it being aluminum that means it can't handle as much stress. The only problem I see with the BBR is that it is made of a sofer metal. I don't know what the Banke is made of. The Banke was designed for flat track. So there is the possibility of it breaking.

    So what would you recommend? It's mainly going to be a Supermoto Pitbike Racer, maybe mini-roadracer, stunter, off-roader. But no big jumps, I've got my 400 if I feel like getting off the ground.

    I have a banke brace on my roadracer. Sturdy steel construction, fits well and half the price of the bbr.

    Thanks for the feedback. Do you think it's strong enough for SM or MX?

    I personally run the BBR. It offers more protection with the skid plate.

    It is pretty sturdy. It does reduce ground clearance somewhat. Not an issue for motard but maybe for actual motoX. Brace made a noticeable difference in feel
    (I have been chasing chatter front to back since I started developing this bike)

    How much of a clearance difference do you think there is between this and the BBR?

    From what I've read here and elsewhere, it seems like the Banke is stronger, but I don't know if the clearance would be an issue.

    That's a pretty sweet 100. I really like the way the BBR brace looks like it fits. Do you think it's strong enough to keep the frame from flexing under 260 lbs?
    I know you mentioned the chain swap in another thread, how big of a difference did that make? Is it weaker?

    I'm sure that it will work fine. There is only so much that you can do to frame. It is not the strongest to start with.
    The chain swap is a necessary mod if class rules restrict the amount of mods allowed. The class that I mini-roadrace the XR100 doesn't allow engine work beyond a big bore up to 125cc with the stock carb. No headwork allowed. Every little 'speed secret' helps!

    i still cannot be convinced that a frame brace will do squat on a 100. for the frame to stretch the cases would have to break. my 1990 100 still had all the bolt holes line up after removing the motor for the first time ever last winter.

    Everyone has their own opinions and experiences. But I noticed that a majority of the xr100 racers that don't have a frame brace do experience the frame stretching. The suspension is poor, so the frame takes a lot of stress. It also depends on the type of terrain you are riding. Here in the NorCal SMUSA series, the dirt jumps can be really big for the xr100's.

    Wow! I have tried big airs with mine but the landings hurt my ankles. I am also a horrible dirt rider!!!

    Sounds like either one is good, so... Considering the price difference I think I'm going to get the Banke. Thanks everybody for the feedback.

    Almost any any XR 1/4 turn throttle will work.
