I found a new supplier for 19” conversion kits.
Street trackers and Hooligan racers need a 19" rear wheel so dirt track tires can be used (dirt track tires are only made in 19”). The cheapest source of a 19" wheel for the rear is buying another front. Yes, gigantic tires can be mounted on narrow 2.15” wheels.
Kit A for 9-Spoke Wheels
Bolt-on conversion kit allows you to mount a 9-spoke front 19” Sportster wheel on the rear. It will fit cast and spoked wheels designed for ¾” axle from 1986 to 1995. Kit contains 2 big spacers, 2 little spacers, ten 7/16” cap screws, 3 sealed bearings and a long bearing inner crush spacer. The 5/16 holes in your wheel have to be drilled and tapped for 7/16"-14 cap screws. Have a local machinist do this.
Kits D and E for 13-Spoke Wheels with ¾” Axles
When you order a kit for a 13-spoke cast wheel I need these specs:
- ¾” (19mm)
- 1” (25mm)
2. What is outside diameter of wheel collar around the bearings? (Same as ID of rotor/sprocket hole.)
- 1.975"
- 2.208”
3. What is the mount face-to-mount face wheel across the hub where rotor and sprocket mount?
- 4.055”
- 4.391”
