    I just purchased a direct drive rim for the rear! I ordered the band brake. I also ordered the 44 thooth gear!
    It is on the hs 50cc motor with a grubee trans! Has anyone had the ability to try this???
    I know it is going to be a dog off the line, but top speed shoud work out to about 48 MPH. ( i am guessing) The 56 thooth gave me 31 mph!
    I have just finished it! Haven't ridden it yet! Will let all know how it works out tonight!:grin5:

    3.7:1
    44 tooth = about 41 mph

    48 tooth = about 38 mph

    It took a downhill slope to achieve top speed. (after reaching top speed it held it) It made it to 49 MPH. I think the 50 is the next to try!
