    Everyones numbers are right about dead on. If you put in the gearing according to the gearing/speed calculator here: http://home.earthlink.net/~gellett/ltz400.htm
    It's right on. I went to a 39t rear sprocket and I top out at 67 mph on the flat and 69.5 downhill. I weigh about 180 and all I've done to the machine is dynojets, airbox lid removal, and removed the endcap.

    I threw on a set of 22" ITP Blackwaters on 8" steel rims (heavier than the stock 20's by quite a bit). After dropping one tooth on the front sprocket I'm hitting 65 on the flat and 67 on the downhill. The increased ground clearance is well worth the reduced top speed.
