Shinko Motorcycle Tires SR777 HD Rear Cruiser Tire MU85-16 Black Wall — Heavy‑Duty, Aramid‑Belted

The Shinko SR777 HD MU85B16 77H is a heavy‑duty black‑wall rear cruiser tire engineered for stable handling, increased load capacity and confident wet‑and‑dry traction on V‑Twin and metric cruisers.

This rear tire is built specifically for cruiser motorcycles and offered in sizes that fit many V‑Twin and metric cruiser models. Its rubber compound balances grip and comfort while the tread pattern uses functional siping and longitudinal grooves to evacuate water and maintain contact on dry pavement. The HD (Heavy Duty) carcass and aramid belt add stiffness and load capability so you feel a planted, predictable response when you accelerate, brake or lean into a turn.

How does the SR777 HD improve grip and comfort for cruiser riding?

The tire compound is formulated to give consistent traction without a harsh ride, blending a compliant carcass with a tacky tread formulation. This helps maintain traction during everyday riding while avoiding excessive road vibration.

• Rubber compound tuned for a balance of grip and ride comfort
• Tread siping increases bite on damp surfaces
• Grip characteristics designed for common cruiser speeds and loads

What makes the Heavy Duty (H.D.) construction different?

The HD designation means a reinforced carcass and an aramid-belted structure that increases stability under load and reduces sidewall flex. That reinforcement helps the rear stay planted during hard acceleration, carrying luggage, or with a passenger aboard.

• Reinforced carcass for reduced sidewall deformation
• Aramid belt for added strength and better load distribution
• Higher confidence when carrying heavier loads or riding two-up

How does the tread design perform in wet and dry conditions?

The SR777 HD uses a combination of longitudinal grooves and carefully placed siping to channel water away from the contact patch while maintaining a continuous rubber footprint for dry grip. The pattern prioritizes predictable handling and consistent braking feel on a variety of road surfaces.

• Longitudinal grooves quickly evacuate water
• Functional siping improves wet traction and braking feel
• Tread geometry maintains stable cornering response on dry roads

Will this tire fit my bike and what are the key specifications?

The MU85-16 size with a 16" rim diameter fits many rear applications on cruiser models; check your motorcycle’s placard or owner’s manual and verify with a tire professional before purchase. Speed and load ratings are important: this tire carries a 77 load index and an H speed rating.

• Size: MU85‑16 (rear application)
• Rim diameter: 16 inches
• Load rating: 77; Speed rating: H
• Designed for cruiser/street use on V‑Twin and metric cruisers

Who is this for? The Shinko SR777 HD MU85B16 77H is aimed at cruiser riders who want a robust rear tire with reinforced construction for better stability under load, improved wet‑weather traction and a comfortable ride. It’s a solid choice for solo riders, two‑up touring, or anyone who regularly hauls weight or runs a heavier rear setup on V‑Twin and metric cruiser machines. Always confirm compatibility with your motorcycle’s specifications and consult a tire technician for mounting and inflation recommendations.
