Harley Sportster 39mm (2004–2022 Select XL Models) Billet Triple Tree Assembly | OEM Replacement

Cognito Moto CNC-machined Billet Triple Tree Assembly for Harley Sportster 39mm (2004–2022 Select XL Models), styled after our existing fixed-offset billet triple tree design but developed for factory Harley forks and original chassis geometry. This is an OEM-style replacement, not a fork swap.

Intended Harley applications

Selected 2004–2022 Sportster XL883/XL1200 motorcycles equipped with OEM 39mm conventional forks. Excludes factory 49mm Forty-Eight versions, 43mm inverted Roadsters, XL1200CX, and other altered fork/triple configurations unless confirmed. 2004-on frame generations, stems and upper/lower clamp fitments must be checked by year and exact model.

Specifications

• CNC-machined billet 6061-T6 aluminum
• Available in bare aluminum or anodized black
• Retain stock factory fork configuration, clamp spacing and original steering geometry once measured and validated
• No aftermarket offset selection; factory offset for each confirmed application
• Made to order at Cognito Moto

Included

• Billet upper and lower triple clamps, standard billet profile
• Factory-geometry steering stem and top retaining nut as required for confirmed application
• Steering-stop arrangement matched to the OEM frame

Factory steering bearings, handlebar risers, rubber bushings, headlight and forks are not included unless specifically confirmed. This is not a conversion-bearing kit.

Riser mounting option

Choose an undrilled upper clamp or drilling for stock Harley-style rubber-bushing riser mounts on 3.5-inch (88.9mm) centers. Drilling adds $23, matching our existing riser drilling service. Bushings and risers are not included. For different spacing, a solid-mount arrangement or other custom setup, contact us with measurements before ordering.

Bottom-mount headlight option

Choose no lower-tree headlight provision, or a Bates-style bottom-mount headlight hole for a suitable lower-clamp location. This option creates a mount provision only; it does not include a headlight or bracket. Final hole size, thread, location and available material must be checked against the actual headlight and clamp design. This option currently carries no additional draft price.

Design and fitment confirmation required: This is an unverified, made-to-order product draft. Final OEM upper and lower clamp part numbers, upper/lower clamping diameters, fork spacing, offset, steering-stem geometry, handlebar bushing fit, steering stops, wheel/brake clearance and any headlight-mount position must be verified before manufacture and publication. Sample photos from the corresponding Cognito Moto design are style references, not finished Harley-specific fitment photography. Please supply the Harley year, model and OEM front-end configuration for fitment review.
