Steel rear sprocket for extended wear life
More durable than aluminum for street applications
Gearing & Performance
Quick Acceleration Setup
This kit improves acceleration primarily through a shorter front sprocket and reduced drivetrain mass.
Designed around a 15T front / 45T rear setup
Shorter gearing than stock for improved acceleration
Faster throttle response and quicker revving feel
Helps the engine reach its powerband more quickly
Improves drive out of corners and roll-on response
Stock vs This Kit
Stock Yamaha YZF-R6: 16T front / 45T rear — 525 chain (114 links)
This kit: 15T front / 45T rear — 520 chain (114 links)
Smaller front sprocket = quicker acceleration
Maintains rear sprocket size for balanced gearing
Reduced drivetrain mass improves responsiveness
More aggressive and lively overall feel
Real-World Feel
Noticeably quicker throttle response
Stronger pull in lower gears
More immediate acceleration feel
Retains good highway usability compared to extreme gearing changes
Why Switch to 520 Over the Stock 525?
Performance vs Durability Tradeoff
The R6 comes equipped with a 525 chain from the factory for durability and long service intervals. A 520 conversion is a common performance upgrade.
520 chain is narrower and lighter than 525
Reduces rotating mass in the drivetrain
Allows the engine to rev more freely
Improves throttle response and riding feel
Common upgrade for sport and track riders
What Actually Makes the Difference
You are not gaining horsepower from reducing chain size alone
The biggest performance gain comes from gearing changes
The 520 setup enhances responsiveness and feel
525 remains better for maximum longevity and heavy use
Why These Kits Are Popular
Riders often replace chain and sprockets together
Combines gearing upgrade + chain conversion in one kit
Performance riders prefer lighter drivetrain setups
Simple, complete upgrade over stock components
Ideal Use
Best For Riders Who Want More Response
Street riding
Aggressive sport riding
Track day use
Riders upgrading from stock drivetrain feel

RK 520 Quick Acceleration Chain & Sprocket Kit Gold Yamaha YZF-R6

Product Overview

The RK 520 Quick Acceleration Chain and Sprocket Kit is designed to give the Yamaha R6 a sharper, more responsive feel by reducing drivetrain weight and optimizing gearing for acceleration.

This is a full 520 conversion kit, replacing the stock 525 chain and sprockets with a lighter 520 setup. Combined with a shorter front sprocket, this kit improves throttle response, helps the engine rev quicker, and makes the bike feel more aggressive without sacrificing everyday usability.

Key Technology & Design

520 Conversion System (Complete Replacement)

This kit replaces the entire OEM drivetrain with a matched 520 system.

Includes 520 front sprocket, rear sprocket, and chain
Converts from stock 525 to 520 setup
Reduces rotating mass for improved responsiveness
Designed as a complete matched performance package

Chain & Sprocket Compatibility

Chain and sprocket sizes must always match.

520 chain must be used with 520 sprockets
525 chain must be used with 525 sprockets
Mixing sizes will cause improper fitment and premature wear
This kit replaces everything to ensure proper compatibility

Premium 520 XW-Ring Sealed Chain

RK’s XW-ring chain is built for high-performance street and sport riding.

520 XW-ring sealed chain construction
Gold finish for premium appearance
Rivet-style master link included
Rated at 42 kN / 9,450 lb tensile strength

Steel Sprocket Construction

Built for durability while supporting aggressive riding.

Steel front sprocket for strength and reliability
Steel rear sprocket for extended wear life
More durable than aluminum for street applications

Gearing & Performance

Quick Acceleration Setup

This kit improves acceleration primarily through a shorter front sprocket and reduced drivetrain mass.

Designed around a 15T front / 45T rear setup
Shorter gearing than stock for improved acceleration
Faster throttle response and quicker revving feel
Helps the engine reach its powerband more quickly
Improves drive out of corners and roll-on response

Stock vs This Kit

Stock Yamaha YZF-R6: 16T front / 45T rear — 525 chain (114 links)
This kit: 15T front / 45T rear — 520 chain (114 links)
Smaller front sprocket = quicker acceleration
Maintains rear sprocket size for balanced gearing
Reduced drivetrain mass improves responsiveness
More aggressive and lively overall feel

Real-World Feel

Noticeably quicker throttle response
Stronger pull in lower gears
More immediate acceleration feel
Retains good highway usability compared to extreme gearing changes

Why Switch to 520 Over the Stock 525?

Performance vs Durability Tradeoff

The R6 comes equipped with a 525 chain from the factory for durability and long service intervals. A 520 conversion is a common performance upgrade.

520 chain is narrower and lighter than 525
Reduces rotating mass in the drivetrain
Allows the engine to rev more freely
Improves throttle response and riding feel
Common upgrade for sport and track riders

What Actually Makes the Difference

You are not gaining horsepower from reducing chain size alone
The biggest performance gain comes from gearing changes
The 520 setup enhances responsiveness and feel
525 remains better for maximum longevity and heavy use

Why These Kits Are Popular

Riders often replace chain and sprockets together
Combines gearing upgrade + chain conversion in one kit
Performance riders prefer lighter drivetrain setups
Simple, complete upgrade over stock components

Ideal Use

Best For Riders Who Want More Response

Street riding
Aggressive sport riding
Track day use
Riders upgrading from stock drivetrain feel
