GIGACYCLE GARAGE MACHINED PARTS FOR HARLEY SPORTSTER AND FXR BUILDS

Gigacycle Garage produces a focused range of precision-machined Harley-Davidson parts built for builders who are pushing the stock Sportster or FXR platform into tracker, hooligan, scrambler, and custom conversion territory. Every part in the collection addresses a specific problem on a specific platform, designed by people who are actually building and riding the bikes these parts go on.

SPORTSTER TRACKER AND CONVERSION PARTS

The most distinctive parts in the Gigacycle lineup are built around the Sportster as a tracker or off-road conversion platform:

• Sportster Sprocket Cover (1986-2003): The stock Sportster diecast sprocket cover is a weak point on tracker and Baja-converted builds. The Gigacycle machined replacement provides a solid platform to mount the right side footpeg, brake pedal, and master cylinder. Designed specifically for Baja and tracker-style Sportster conversions where the stock cover does not hold up to the demands of the build direction. Fits 1986 to 2003 Harley-Davidson Sportsters.

• LeRoy Hooligan Tracker Complete Front End Kit (1982-Up Sportster): A complete machined front end kit for hooligan and tracker Sportster builds. The most comprehensive Gigacycle offering for builders converting a Sportster into a proper tracker or flat track-influenced street bike from the front end down.

4-PISTON REAR BRAKE CALIPER BRACKETS

Gigacycle produces platform-specific and universal rear caliper brackets for builders running 4-piston calipers on non-standard brake setups:

• Universal 4-Piston Rear Brake Bracket for Rigid Frame or 1982-2003 Sportsters: Machined bracket for rigid frame and Ironhead/Evo Sportster swingarm applications. Built for builders converting to a 4-piston caliper on platforms where no factory mount exists.

• Universal 4-Piston Rear Brake Bracket, Swingarm Applications, 3/4-Inch Axle: Universal swingarm version for 3/4-inch axle builds where the platform-specific bracket does not apply.

• 4-Piston Rear Brake Bracket for 1982-94 and 1999-2000 FXR: FXR-specific caliper bracket for builders running a 4-piston setup on FXR frames, covering the early and late FXR production runs.

FXR CONVERSION AND FRAME HARDWARE

• Twincam to FXR Frame Conversion Oil Pan Block Off Plate: Machined block-off plate for builders swapping a Twin Cam motor into an FXR frame. The oil pan profile does not match the FXR frame opening directly, and this plate bridges the gap for a clean, leak-free conversion install.

• FXR Side Panel Screws and Seat Screw: Hardware sets for both OEM-style and Arlen Ness-style FXR side panels. The precision-machined screws replace the standard hardware with a finished piece that matches the quality of the side panel itself.

CAPS AND SEAT HARDWARE

• Left Side Non-Vented and Right Side Vented Gas Caps for 1992-Up Harley-Davidsons: Machined gas caps in the correct vented and non-vented configuration for the left and right side of post-1992 Harley gas tanks. Browse motorcycle gas caps for the full range of gas cap options.

• Locking Push-In Oil Cap: A machined locking oil cap for builders who want a cleaner, more secure alternative to the standard push-in cap on custom oil tanks.

• Seat Bolts: Machined seat bolts in 1/4"-28 thread for pre-1997 Harley-Davidsons and 1/4"-20 for 1997-up applications. A visible fastener on most builds, machined to the level of finish the rest of the hardware deserves.
