Fits Harley Sportster 1991 to 2003 and Buell 1991-2003. Alloy super lite 28 Tooth Transmission Belt drive Pulley. One tooth in the front, is like 3 in the back. 28 Teeth will gear you up a little for the XL 883 (More top end speed, longer rev’s, longer shifts in between gears, less toque off the line and at the start of every gear).
i bought this 28-tooth sprocket to give me an intermediate ratio between the 26 the bike came to me with and the optimistic 30 i bought. i run the bike at the land speed races and needed a spread of ratios to maximize speed. the 1997 buell cyclone would not pull the 30 above 128 mph, but when i switched to the 28 it went 130 at the mile and 132 at the mile point five.
the sprocket is excellent quality, comes with a nut, locking ring, and allen cap screws to hold it in. other kits sometimes include the seal assembly but it's not really needed.
