Factory Fluid StandardDirect Spec

Maxima Racing Fork Fluid 5W (1 Liter)

Formulated with anti-foam agents and shear-stable viscosity index improvers to prevent damping fade under aggressive riding heat.

Fork & Dust Seal KitExact Stanchion Fit

All Balls Racing 41mm Fork & Dust Seal Kit

Features directional triple-lip rubber seal profile and external garter springs engineered to withstand heavy stanchion flex without weeping.

Air-Gap Tuning PhysicsBottoming Control

102 mm (4.02 in) compressed, spring removed

Trapped air column acts as a progressive spring in final 30% of stroke. Adding +5mm oil increases bottoming resistance without stiffening small bump compliance.

Received: 07/10/2014▼

Defect Description

Suzuki Motor of America, Inc. (Suzuki) is recalling certain model year 2011-2014 GSX-R750 and 2009-2014 GSX-R1000 motorcycles. If a gear is missed while upshifting, the strain applied to the drive chain after the next shift may cause the rear axle to move, damaging the left-side drive chain adjuster.

Safety Hazard / Consequence

If the drive chain adjuster gets damaged, the drive chain may come off, removing power to the rear wheel, and increasing the risk of a crash.

Factory Remedy & Repair Action

Suzuki will notify owners, and dealers will replace the left-side chain adjuster with an improved part. The recall began on October 17, 2014. Owners may contact Suzuki customer service at 1-714-572-1490. Suzuki's numbers for this recall are 2A40, 2A41, 2A42 and 2A43.

Manufacturer Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
