Factory Fluid StandardDirect Spec

Maxima Racing Fork Fluid 10W (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 37mm 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

160 mm (6.30 in) slider compressed

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

NHTSA #14V211000POWER TRAIN:MANUAL TRANSMISSION

Received: 18/04/2014▼

Defect Description

BMW of North America, LLC (BMW) is recalling certain model year 2013 R 1200 GS motorcycles manufactured November 2012 through August 2013. Pressure inside the transmission may cause the transmission output seal to be pushed out of place.

Safety Hazard / Consequence

If the output seal ring is pushed out of its proper position, oil may leak from the transmission onto the rear tire, increasing the risk of a crash.

Factory Remedy & Repair Action

BMW will notify owners, and dealers will fit a bracket to prevent the transmission seal from being pushed out of position, free of charge. The recall began on June 17, 2014. Owners may contact BMW customer service at 1-800-525-7417.

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.
