The Yamaha Aluminum Performance Damper for the 2024–2026 MT-09 and XSR900 series (Manufacturer Part Number: Q5K-YSK-146-F01 ) is a premium chassis stabilization system. Unlike a steering damper which controls side-to-side handlebar wobble, this performance damper is an evolution of Yamaha's automotive technology designed to suppress microscopic structural vibrations and frame flexing during riding.
Product Features
-
Chassis Vibration Dampening: Specifically tuned to target micro-deformations and high-frequency oscillations of less than 1 mm that propagate through the motorcycle's frame while in motion.
-
Enhanced Comfort and Smoothness: By converting kinetic energy and frame flex into tiny amounts of thermal heat, it significantly reduces buzzing felt through the footpegs, seat, and handlebars. This produces an incredibly smooth, fluid ride quality over long-distance tours.
-
Upgraded Aluminum Body: Features a lightweight, high-rigidity structural aluminum casing housing the internal oil-valving mechanism, distinguishing it visually and mechanically from older generations.
-
Optimized Vehicle Stability: Suppresses the sudden flex responses of the frame when hitting road bumps, stabilizing the bike's line-holding characteristics through sweeping highway turns.
-
Vehicle-Specific Stay Brackets: Includes the exact black-finished mounting arms, spacers, and heavy-duty steel bolts required to bolt the damper onto the right-side frame rails of late-model CP3 engines without cutting or drilling.
