At DMG Motorsports, we present the Pirelli Scorpion Rally STR in size 90/90-21 M/C 54V M+S TL (A) — the ultimate front tire for adventure and dual-sport riders who refuse to compromise. Part of Pirelli's legendary SCORPION™ range, the Scorpion Rally STR is the road and on/off touring tire for riders who want the bold, knobbly look and genuine off-road capability, but demand outstanding grip, safety on wet surfaces, and comfort both on-road and off. Whether you're carving canyon roads, cruising the highway, or venturing onto gravel, sand, or dirt trails, this tire delivers the confidence and versatility to take on every condition with authority.
Features:
- True Rally-Meets-Street Performance: Combines significant rally capabilities with great street performance — technological innovations provide traction on dirt, stability at high speeds, on-road handling agility and grip in all riding conditions.
- High-Silica Compound (55%+ Silica Content): A single-layer tread compound with a silica content greater than 55% delivers increased grip on both dry and wet surfaces, superior abrasion resistance, high tear resistance, and stability — including in low-temperature conditions.
- Pirelli's Exclusive Patented Blending Process: Silica and carbon black are combined with new resins, oils, and polymers using Pirelli's proprietary process, maximising compound cohesion for stable, long-lasting performance.
- Enlarged Contact Patch for Greater Stability: Increased width and length of the tire's contour creates a larger contact patch, boosting stability on-road and building confidence at highway speeds.
- Optimised Knob Geometry: Blocks are longer and wider, and the longitudinal distance between each row of knobs has been reduced to increase the contact patch without compromising off-road traction — a brand-new height-to-width ratio unique to the market.
- Advanced Heat Management: Heat generated by high-speed riding is distributed across a wider surface area to prevent knob tearing, extending tread life under demanding conditions.
- Street-Derived Profile & Structure: Road-optimised profiles and carcass structure provide a large, consistent, and confidence-inspiring contact patch that works seamlessly with sophisticated rider electronics such as cornering ABS and traction control.
- Off-Road Inspired Knob Pattern: Aggressive knobbly tread design — inspired by the venerable Scorpion Rally — with an increased land-to-sea ratio for on-road stability, while still excelling on gravel, sand, and dirt.
- OEM-Trusted Fitment: Fitted as original equipment on leading adventure platforms including the Yamaha Ténéré 700, Ducati Desert X, and Husqvarna Norden 901 Expedition.
- Specifications: Size 90/90-21, Load Index 54, Speed Rating V (54V), M+S (Mud & Snow) rated, Tubeless (TL), (A) front fitment designation — designed for 21-inch front wheels on adventure and dual-sport motorcycles.
