Luxon N2D Knuckle - Gas Gas, KTM, Husqvarna 2025-2027
Luxon high performance linkage knuckle addresses the shortcomings of the KTM/Husqvarna/Gas Gas rear suspension. The corrected motion ratio of the rear suspension delivers increased traction, bottoming resistance, and predictable handling. See the description section below for more details.

Luxon knuckle maintains stock ride height, increases holdup mid-stroke, and is more progressive near the end of stroke for more bottoming resistance. This allows for a softer setup to provide a more plush ride early in the stroke which better absorbs chatter and small bumps and increases traction. The revised motion ratio still provides better bottoming resistance than stock.
Bolt it on, check your sag and go. Luxon recommend softening up your low and high speed compression and adjusting from there as needed. Precision machined from billet aluminum, clear anodized, and laser etched. Includes OEM bearings and seals pre-installed.
Want an outside opinion? Read the MXA test and review of this knuckle (*The review is for the 2024 version, but the 2025-2026 has an identical motion ration, just different bearings, so the performance changes are the same.)
This knuckle is NOT compatible with some lowering links. It is compatible with Luxon adjustable link arm, but heavier weight springs may interfere with the swingarm at the +3 or +4 mm adjustment lengths (all other lengths will work fine). Soft springs may not interfere at all (it's a tight fit at the swingarm and heavy springs are bigger).
KTM and Gas Gas Fitments
No linkage arm and no spring change required. Re-valve through @n2_dirt always recommended, but not strictly required.
Husqvarna Fitment
No spring change required. Re-valve through @n2_dirt always recommended, but not strictly required. This knuckle is designed around the KTM/Gas Gas geometry, so on a "10 mm lowered" Husqvarna, it will raise the ride height by about 5.4 mm in the rear. This can be addressed by using Luxon adjustable link arm in the 2 mm longer setting (3 dots) to bring the rear end back down.
