Shinko Motorcycle Tires SR777 HD Cruiser Rear Tire 140/90B16 77H — Heavy-Duty, Wet/Dry Traction

The Shinko SR777 HD 140/90B16 77H is a heavy-duty bias rear tire engineered to give cruiser riders stable handling, improved wet/dry traction, and higher load capacity for V‑Twin and metric cruisers.

Built for long, planted miles on cruiser motorcycles, the SR777 HD blends a compliant rubber compound with a reinforced carcass and aramid belt to deliver predictable grip while accelerating, braking and leaning. The tread pattern employs purposeful siping and grooves to evacuate water and maintain contact on varied pavement, and the Heavy Duty construction increases stability under load. Available in multiple sizes to suit many rear-wheel applications, this tire is a practical option for riders seeking a balance of comfort and confidence.

How does the SR777 HD improve traction in wet and dry conditions?

The SR777 HD uses a tread geometry with functional siping and directional grooves to channel water away from the contact patch while preserving surface area for dry grip. The rubber compound is tuned for adhesion and ride comfort, so you feel secure during acceleration and braking without a harsh ride.

• Directional grooves that disperse standing water
• Siping for small-stone and surface bite
• Compound balanced for grip and rider comfort

What makes the Heavy Duty (H.D.) version more stable on a loaded cruiser?

The H.D. model features a reinforced carcass and an aramid belt that increase structural rigidity and load capability compared with a standard bias tire. This reinforcement reduces flex under load, translating to a steadier feel at highway speeds and when carrying passenger or luggage weight.

• Reinforced carcass for reduced sidewall flex
• Aramid belting for enhanced load capacity and stability
• Improved feedback when cornering or braking under load
