Renthal 525 Pitch Front Sprocket for Yamaha Tenere 700 - 16T

The Renthal Front Countershaft Sprocket (309-525-16P) is engineered to deliver exceptional durability and maximum power transfer to the rear wheel. CNC-machined from a specialized nickel-chrome-molybdenum alloy steel, the sprocket undergoes a rigorous case-hardening and core-refinement process. This treatment creates an incredibly hard, wear-resistant outer surface for the chain rollers to ride on, while maintaining a tough inner core capable of withstanding the severe shock loads of aggressive acceleration.

Unlike traditional stamped OEM sprockets, Renthal utilizes computer-engineered profiling to ensure perfect concentricity, exact fitment on the countershaft splines, and precise chain alignment. This specific model features an ultralight design with strategic lightening holes to reduce rotational unsprung mass without compromising the structural integrity required for high-torque motorcycles.

Features:

• Premium Alloy Steel: CNC-machined from nickel-chrome-molybdenum steel for maximum tensile strength and durability.

• Case-Hardened: Specialized heat treatment creates a highly wear-resistant surface that significantly extends drivetrain life.

• Precision Profile: Computer-engineered tooth profiling ensures perfect concentricity and flawless mating with a 525-pitch chain.

• Lightweight Design: Strategic lightening holes reduce rotational mass for improved throttle response and acceleration.

• Direct Replacement: Precision-cut splines ensure a tight, slop-free fit on the factory countershaft.

Fitment: 

• 2020–2024 – Yamaha Tenere 700

• 2014–2024 – Yamaha MT-07

• 2014–2025 – Yamaha MT-09

• 2015–2025 – Yamaha R1

Fitment Note:

• 2025+ Yamaha Tenere 700 changed to a 520 pitch drive train. 
• Replace the Lock Washer: When installing a new front countershaft sprocket, you must flatten the bent tabs of your factory lock washer. Metal fatigue occurs once these tabs are bent back and forth. It is highly recommended to purchase a brand-new OEM lock washer from your dealer rather than reusing the old one to ensure the countershaft nut cannot back off while riding.
• Drivetrain Wear: You should always replace your drivetrain components as a complete set (front sprocket, rear sprocket, and drive chain). Installing a brand-new front sprocket onto an old, stretched chain will cause the new sprocket's teeth to "hook" and wear out at a drastically accelerated rate, wasting your investment.
