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.

KEY FEATURES

• Precision machined from billet aluminium, clear anodised, and laser etched.
• Includes OEM bearings and seals pre-installed and fit

Want an outside opinion? Read the MXA test and review of this knuckle here in Luxon review section! (*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 +3mm or +4mm 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).

No spring change required. Re-valve through @n2_dirt always recommended, but not strictly required. This knuckle is designed around the KTM/GasGas geometry, so on a "10mm 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 2mm longer setting (3 dots) to bring the rear end back down.
