    BBR Super Pro Frame - What steering stem bearings?

    Hey man I have a question.. Hopefully you can answer it for me. I just bought a crf50 with the bbr super pro frame/swingarm. It has the marzoocchi shiver forks. There is a little bit of play between the steering stem and the head of the frame. Im thinking I need new steering head bearings. The question is where and what bearings do I need? It's tough because I don't have a stock frame or stock forks. So I haven't found any info. The only steering head bearings I can find is for a crf50. I don't want to buy the wrong s**t.

    Mister Motard,
    measure the ID of the steering stem neck on the frame, and also the OD of the two areas on the steering stem where the upper and lower bearing races sit. The upper area on a 50 stem is 22.5mm and the lower area is 24mm. I have an old outer bearing race here that I can measure to let you know the ID of a stock 50 neck.

    EDIT: The OD of the outer bearing race for the 50 frame is 40.99mm
