Shinko 005 Advance Motorcycle Tire Set 120/70‑21 Front & 240/40R18 Rear 21"/18" Sport Cruiser Tires V‑Rated

OVERVIEW

This matched motorcycle tire set delivers balanced traction and durable handling specifically engineered for sport cruiser applications. Designed as a complete front-and-rear pair, the setup combines a traditional bias-ply front tire with an aramid-belted radial rear to optimize stability across different riding conditions. Both units utilize structured rubber compounds and are built to meet the weight and performance profiles of modern custom motorcycles.

ENGINEERING & PERFORMANCE

The front 120/70-21 bias-ply unit provides nimble steering response while the redesigned 240/40-18 radial rear carries heavy loads with an integrated aramid belt for enhanced high-speed stability. Consolidated large-block tread geometry spans both tires, creating broad contact patches that translate engine power directly to the road surface and resist sidewall deflection during leaned cornering. Routed groove channels act as water-dissipating paths through the tread blocks to maintain mechanical grip during wet weather operation.

WHY RIDERS CHOOSE THIS

Riders select this paired arrangement because it separates front-end agility from rear-end high-speed stability, matching bias construction where steering precision matters and aramid-belted radial support where grip under acceleration is critical. The uniform block tread design minimizes uneven wear while delivering predictable friction loads during straight-line cruising and leaning maneuvers. Factory-matched dimensions simplify mounting and ensure consistent wheel alignment, allowing riders to install a fully optimized chassis package without custom sizing guesswork.
