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

105 mm (4.13 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: 18/12/2025▼

Defect Description

Honda (American Honda Motor Co.) is recalling certain 2024-2026 CBR600RR motorcycles. The cylinder head may have been improperly manufactured, which can lead to rod bearing failure, possibly resulting in rear wheel lock up or oil leaking onto the rear tire.

Safety Hazard / Consequence

Rear wheel lockup increases the risk of a crash or injury. Engine oil that leaks onto hot exhaust components increases the risk of a fire.

Factory Remedy & Repair Action

Dealers will replace the engine assembly, free of charge. Interim letters notifying owners of the safety risk were mailed February 9, 2026. A second letter will be sent once the remedy is available, anticipated October 31, 2026. Owners may contact Honda's customer service at 1-866-784-1870. Honda's numbers for this recall are KT5 and KU3. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning January 7, 2026.
