MINO Fusion Dual Ring Rear Sprocket for Yamaha (48T–52T) Blue

MINO Fusion Dual Ring Rear Sprocket — Lightweight Strength with Steel-Ring Durability

The MINO Fusion Series rear sprocket is designed to give you the best of both worlds: low rotating weight and serious wear resistance. A 7075 aluminium inner ring is paired with a special hardened steel outer ring to deliver long service life in harsh off-road conditions, without the sluggish feel of a full steel sprocket. 

Key Benefits

• 7075 aluminium inner ring paired with a special hardened steel outer ring for low weight and maximum lifespan 

• CAD designed, CNC machined and laser cut using modern manufacturing methods 

• Interlocked dual-ring design eliminates movement between rings 

• Sector-optimised layout for strength where it matters with minimal weight 

• Colour anodised inner ring coating for added strength and durability 

• Race proven on some of the toughest sand tracks in the Netherlands and Belgium 

Ideal For

• Enduro and hard enduro riders wanting long life in mud, grit and rock

• Motocross riders chasing durability without adding rotating weight

• Riders who burn through alloy sprockets too quickly

• Anyone wanting a premium “fit it and forget it” rear sprocket upgrade

Why This Product?

Fusion sprockets are built for riders who want real longevity without sacrificing performance feel. The dual-ring construction targets wear where it happens (the teeth) while keeping overall weight down for sharper acceleration and less drivetrain drag.
