ESJOT Rear Sprocket 525 - Manufacturer Ref. 50-29051-45
ESJOT rear sprocket, designed for the final drive of roadsters, trails/adventure bikes, and sports bikes. Machined from QSTE460 steel and finished in black, this 525 sprocket with 45 teeth showcases German industrial expertise: concentricity and runout tolerances of less than 0.1 mm for a smooth engagement and operation. The finish incorporates the Diamond Cut 2.0 process and a specific surface treatment for a lifespan suited to intensive use.
Ideal for riders seeking a reliable replacement part that meets OEM standards: precise tooth profile, meticulous machining, and robust surface treatment. Suitable for common fits listed for this reference code — including recent Yamaha models such as MT-09 (2025), YZF-R1M (2024), and YZF-R1 (2024) — please check compatibility with your machine before ordering.
