Official Workshop Manual Compression Test Protocol

Step 0 of 5 Completed

Step 1: Engine Operating Temperature

Run engine until coolant reaches 60°C - 80°C (140°F - 176°F). Cylinder expansion brings rings and pistons to true operating clearances.

Step 2: Spark Plug Removal & Port Clean

Blow compressed air around spark plug wells to eject grit, then remove all spark plugs. Thread in M10 x 1.0 whip adapter hand-tight with fresh O-ring.

Step 3: Wide-Open Throttle (WOT) Lock

Hold throttle grip fully wide open (or lock throttle bodies open) to eliminate intake butterfly vacuum restriction and ensure 100% volumetric cylinder filling.

Step 4: Battery Tender Voltage Stabilization

Connect a 12V shop battery tender or booster. Starter must sustain uninterrupted cranking speed (350 RPM) to build maximum dynamic stroke pressure.

Step 5: Crank 4-6 Compression Strokes

Engage starter until gauge needle ceases rising (typically 4 to 6 strokes). Record maximum peak pressure and compare against the OEM limits above.

NHTSA #25V891000ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL

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.

FACTORY WORKSHOP SPECIFICATION:

Critical Recall Safety Countermeasure

CRITICAL WORKSHOP PROCEDURE:

CRITICAL RECALL COUNTERMEASURE (Recall 24V-113 / Bulletins KP9 & KQ0). Original low-density resin impellers absorbed solvent from automotive fuels, swelling and binding against the pump casing to cause sudden engine shutdown while riding. Replacement module features reinforced high-density resin impeller.
