Alpinestars GP Plus V4 Sprint Leather Suit - 1 Piece

Alpinestars GP Plus V4 Sprint Leather 1-Piece Suit

Race-Inspired Performance Without the Pro-Level Price

The GP Plus V4 Sprint is built for riders who want serious track performance without stepping into full factory-level pricing. Drawing technology directly from Alpinestars’ MotoGP development program, this suit delivers a refined balance of protection, flexibility, and comfort—perfect for aggressive street riders and dedicated track day enthusiasts.

Advanced Multi-Material Construction

At the core of the GP Plus V4 Sprint is Alpinestars’ innovative Flex Plus bovine leather, engineered to be more adaptive and flexible than traditional leather while maintaining excellent abrasion resistance. This advanced chassis is combined with strategically placed stretch zones and lightweight materials to enhance mobility and reduce rider fatigue.

Matryx® panels and high-resistance stretch fabric (HRSF) zones improve airflow and structural integrity, giving the suit a modern, race-derived feel without sacrificing durability.

Engineered for Movement

Designed with a performance riding position in mind, the GP Plus V4 Sprint features pre-curved arms and legs, ergonomic panel mapping, and large stretch zones in key flex areas. The result is a suit that moves naturally with your body—whether you're tucked in on a straight or transitioning through corners.

An aerodynamic speed hump enhances stability at high speeds while also improving airflow across the back.

Track-Ready Protection

• GP DFS external sliders for controlled friction and impact protection
• CE-certified armor in shoulders, elbows, and knees
• Reinforced impact zones for added abrasion resistance
• Secure, race-spec stitching throughout critical seams

Every element is designed to protect against impact and slide scenarios while maintaining comfort during extended sessions on track.
