Alpinestars GP Plus V4 Leather Jacket in Black

About this Alpinestars Alpinestars GP Plus V4 Leather Jacket in Black

The Alpinestars GP Plus V4 Leather Jacket in Black offers a refined, "black-out" aesthetic for riders who demand professional-grade performance without loud graphics. Available at On Yer Bike, this fourth-generation icon has been completely re-engineered to provide a more flexible and protective riding experience. Constructed from premium racing bovine leather, the V4 chassis is built to withstand the rigours of high-speed road and track riding while maintaining a supple, comfortable feel.

At On Yer Bike, we recognize that modern safety is about more than just leather thickness. The GP Plus V4 introduces Alpinestars Composite Stretch (AFL) technology—specialized textile panels positioned in key flex zones. These panels offer superior resistance to tearing and abrasion while providing the elasticity needed for the jacket to move with the rider. This design makes the jacket Tech-Air Ready, ensuring it can seamlessly accommodate the expansion of a Tech-Air 5 or Tech-Air 3 Airbag System.

Impact protection is handled by ultra-slim Nucleon Flex Plus armor at the shoulders and elbows, which provides CE-level defense without bulk. This is supplemented by external DFS (Dynamic Friction Shield) shoulder sliders, designed to reduce friction and prevent tumbling during a slide. To ensure comfort across different seasons, the jacket features localized perforations for ventilation and a removable thermal vest liner for cooler mornings. With a full-waist zipper for trouser attachment and a precision sport fit, trust On Yer Bike to deliver the understated power of the Alpinestars GP Plus V4.
