Chrome Rear Scrambler Wheel 40 spoke 18"x 2.5" Fits Sportster 1982-2003 (3/4" diameter wheel bearings).

This is the only 18"x2.5" wheel on the market for Sportsters.

This will enable you to run dual sport offroad enduro style tires on your Harley. 

If you are installing this on a 2000-2003 Sportster you will need to use a 1999-older style flat sprocket or pulley as well as a 1999-older style brake rotor. Your 2000-2003 sprocket/pulley & rotor have too large of center locating holes to fit properly.
