Street trackers and for sure 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 is buying another front. Yes, gigantic tires can be mounted on narrow 2.15” wheels. I now have conversion kits for all the H-D, AMS and Morris 19” front wheels from 1973 to late model 13 spoke wheels with ¾” and 1”’ axles.
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. In a pinch I can have my guy do it (about 69 bucks.)
You don’t have to give me specs to order an A Kit. They are all the same. Avoid using a 9 spoke wheel on a bike that is designed for a 13 spoke wheel. We have not spec’d the conversion out and don’t know how to do this.
Do not attempt to install an A kit made for 9 spoke wheels on a later Sportster designed for 13 spokes. We do not have a kit to do this.
Kits B, D and E for 13-Spoke Wheels
When you order a kit for a 13-spoke cast wheel I need these specs:
1. What is the axle diameter?
- 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”
Kit F for 7-Spoke Morris Wheels
Fits 1973-2003 Sportsters with ¾" rear axles. Kit includes:
- Special big adapters
- Bearings to replace the stock wheel bearings
- 10 Allen screws (7/16" x 1½")
You need to drill out your 5/16" holes and tap for 7/16-14. Kit uses OEM spacers against the swingarm.
