Upside-Down fork Triple Trees for Dyna, FXR, XL

With triple trees from Brock’s Performance, "installing sport-bike fork assemblies in a Harley-Davidson becomes a straightforward bolt-on project." Cut from 6061 T6 billet aluminum, the triple trees are designed to mate a set of Hayabusa fork tubes with Harley-Davidson Dynas, FXRs and Sportsters. A reversible lower triple tree and available fork extensions make it easy to adjust the ride height.

"If you’re looking for quicker turn-in, faster stopping, improved handling in the twisties and overall improved riding performance, a set of upside-down forks with the matching rotors and calipers should be at the top of your list. By sourcing the fork assembly carefully, the whole project can be done on a budget."

They include a stainless stem and zinc-coated steel jam nut and use 1 inch standard H-D tapered bearings and seals. The lower tree is threaded for fork stops and headlight bracket and the upper tree is taped for headlight eyebrow. They accept handlebars with 3.5" spacing, have a cutout for routing wires and brake lines and are spaced for Hayabusa wheels, calipers and rotors.
