The Alpinestars GP Plus v4 Tech-Air Ready leather suit is designed for sport and track riders seeking advanced protection, race-focused performance, and a precise fit. Finished in black and white, this US 44 / EU 54 suit combines Flex Plus racing bovine leather, Alpinestars Composite Stretch Plus material, Matryx panels, HRSF stretch inserts, and GP Dynamic Friction Shield sliders. The manufacturer and vendor part number is 31505231254, making it easy to identify the correct Alpinestars replacement or riding gear application.
The Flex Plus race leather is specially tanned and refined in Italy for a flexible, adaptive feel that supports freedom of movement while maintaining professional racing standards for abrasion and tear resistance. A-CS Plus stretch material adds flexibility, breathability, and improved tear resistance compared with traditional leather accordion panels. Perforated leather across the upper chest, abdomen, and thighs helps promote airflow, while lightweight Matryx material panels on the torso provide additional ventilation and a lower-profile construction when the suit is worn with a compatible Tech-Air airbag system.
Protection includes GP-R armor in the elbows, forearms, knees, and shins, along with Nucleon Race shoulder armor and GP DFS shoulder, elbow, and knee sliders. HRSF stretch inserts are positioned in the crotch, back of the legs, inner arms, and pectoral areas to support an active riding position. Soft stretch wrist and ankle cuffs improve comfort, while the detachable comfort liner features biostatic Polygiene treatment to help maintain freshness. This Alpinestars GP Plus v4 suit is Tech-Air Ready for use with Tech-Air 5 or Tech-Air 10 Airbag Systems and includes a forearm pocket for the Tech-Air 10 remote LED panel. It is suited for riders who need a high-performance leather suit for closed-course riding, track days, and sport-focused motorcycle use.
