This is a factory-supplied 9-tooth (9T) starter pinion gear, specifically designed for the Kawasaki Ninja ZX-10R (ZX10R), a 1000cc superbike. [Perfectly Compatible Models] Compatible Models: Kawasaki Ninja ZX-10R (ZX10R). Important Note: This product is the starter pinion gear, not the complete starter assembly. Please check the exact year and model of your motorcycle before purchasing (different generations of the ZX10R may have variations). Then, remove the starter to ensure its internal pinion gear has 9 teeth. Compare your old pinion gear to the product image from all angles to ensure a perfect match in terms of teeth (or grooves), thickness, outer diameter, and overall shape. Superbikes demand the utmost precision; even the slightest deviations can lead to malfunctions. 【Detailed Specifications and Product Benefits】

Precision Manufacturing for Competitive Quality: The use of high-strength, aerospace-grade alloy steel, precise CNC machining, and special heat treatments ensure absolutely accurate tooth profiles and extremely high surface hardness. This allows it to withstand the starting inertia and high-speed shocks of large-displacement engines.

Original Specifications: Strict adherence to original specifications (9 teeth, module, pressure angle, and bore) and micrometer-level dimensional tolerances ensure perfect, vibration-free engagement with the starter shaft and flywheel ring gear for smooth starting.

Balanced Lightweight and Robust: The lightweight design combined with optimal strength helps reduce rotational mass, thus promoting the rapid starting of high-performance engines.
