Moto-Master 7075 Aluminum Rear Sprocket (47T / Blue) 620072447 - KTM / Husqvarna / Gas Gas / Triumph 1983-2025

Product Description

The Moto-Master 7075 Aluminum Rear Sprocket delivers race-proven performance and weight savings for your dirt bike. Featuring a vivid blue anodized finish, this 47-tooth rear sprocket is manufactured in the Netherlands from high-grade aircraft 7075-T6 aluminum to deliver an optimal strength-to-weight ratio on the track or trail.

Engineered using advanced CAD design and CNC machining, this sprocket is among the lightest options on the market. Integrated self-cleaning grooves between each tooth prevent mud build-up to maintain drive efficiency in tough off-road conditions, while the color-anodized surface treatment protects against wear.

Frequently Asked Questions

Q: What chain size is required for this Moto-Master sprocket?
A: This Moto-Master 7075 aluminum sprocket is designed for a standard 520 chain pitch on your dirt bike.

Q: How do the self-cleaning grooves help in mud?
A: The self-cleaning grooves between each tooth purge packed mud and debris as the chain rolls through, preventing tight spots and reducing excess chain tension in muddy riding conditions.

Expert Pro-Tip: When installing an aluminum rear sprocket, always inspect your chain and front countershaft sprocket. Pairing a new aluminum sprocket with a stretched or worn chain will accelerate tooth wear rapidly. Torque all sprocket bolts in a cross pattern using medium threadlocker, and ensure proper chain slack to avoid binding.
