    Well, on my shift kit, first gear is PERFECT! @ 46.32:1 with 27" tires.

    That's like having a gigantic 113 tooth single rear sprocket.

    I cruise in 7th gear @ 17.72:1, likened to a 43t rear sprocket.

    My highway gear(8th) is 15:1, akin to a 37t rear wheel sprocket.

    With 26" wheels, you can use a higher gear ratio.

    This might NOT be the average ratio, but it works EXCELLENTLY for me.xct2

    Most, if not all chinagirls are 4.1:1 (20T -> 82T).

    Q-matics can vary a lot, but most are in the neighborhood of 3:1.

    Back in the day, it would drive me up the walls to have something at the tip of your tongue and not be able to figure things out.:-||

    I forget what the 2-stroke ratios are, but my EZM tranny gear ratio is 2.50:1 and the overall drive ratio on my bike with the HS49cc engine is 14:1 which gives me a top speed of 38.7mph @ 7,000rpm.
