Starter assembly for KAWASAKI NINJA 650 EX650, short 9-tooth pinion, compatible with original factory starters.

This is a complete, manufacturer-supplied starter with an integrated 9-tooth pinion gear, specifically designed for the Kawasaki NINJA 650 sport touring motorcycle (model EX650). This factory-assembled, ready-to-use starter is distinguished by its short pinion gear (short shaft) – a unique feature of this model. It directly replaces original starters with worn carbon brushes, ignition coil, pinion gear, or solenoid switch due to long-term use. It restores smooth and reliable starting of the twin-cylinder engine. [Compatible Models] Compatible Models: Kawasaki NINJA 650 (EX650) (Applicable to multiple models, please check). Key Features: The short 9-tooth pinion gear has an axial length (thickness) specifically matched to the compact interior of the NINJA 650 starter. This dimension is critical for proper engagement and mounting with the flywheel ring gear. **Important Note:** This product is a complete starter assembly. Please verify that your vehicle is indeed a NINJA 650 (EX650 platform) before purchasing. We strongly recommend comparing your old starter to the product images, paying particular attention to the thickness (length) of the drive pinion, as well as the overall shape, mounting flange, and electrical connection (plug type). [Detailed Product Specifications and Benefits] **Precise and Perfect Fit:** The 9-tooth pinion is manufactured to the exact specifications of the original EX650 model, ensuring precise engagement and optimal axial clearance with the flywheel ring gear. This eliminates installation problems and excessive wear. **Efficient and Smooth Starting:** Optimized for the 650cc parallel-twin engine, the starter delivers high and consistent starting torque for quick, quiet starts and an enhanced riding experience. Durable and reliable: The robust housing features wear-resistant carbon brushes and high-performance bearings. The short 9-tooth pinion gear, made of alloy steel, is heat-treated for exceptional durability. Ready to use: This product arrives fully pre-assembled. The gears are correctly mounted on the motor shaft, eliminating any concerns about the complexity or precision of assembly.
