Shinko 777 Heavy Duty 90/90‑21 Front Tire | SR777 Cruiser V‑Twin Tire | 90/90‑21

OVERVIEW

The Shinko SR777 is a 90/90‑21 front tire engineered to deliver reliable traction and structural reinforcement for cruiser motorcycles. Constructed from a heavy‑duty rubber compound layered with aramid‑belted reinforcement, this tire provides the durability required for heavier V‑Twin and metric platforms. It functions as a direct replacement that restores front‑wheel specifications while accommodating elevated load demands.

ENGINEERING & PERFORMANCE

Aramid belt wrapping combined with a reinforced carcass ensures high‑speed stability and withstands the mechanical stress of larger cruiser engines. The tread pattern uses functional siping and strategically positioned grooves to manage water displacement and bite into pavement, delivering consistent grip across changing road conditions. Optimized rubber formulations balance long‑term wear with responsive handling, making it a dependable replacement for riders restoring front‑end performance without compromising load capacity.
