The Tech-Air® Ready GP Plus v4 Leather Suit represents a complete revolution in motorcycle track gear, featuring an all-new construction engineered for sport and track riders who demand the latest material innovations. This suit blends performance with comfort by utilizing Flex Plus racing bovine leather, specially tanned and refined in Italy. This ultraflexible leather is highly adaptive to the body, supporting a 6% adaptability ratio—80% more than regular bovine leather—resulting in unrivalled feel, freedom of movement, and a precise fitment.
Engineering excellence is at the core of the GP Plus v4. It incorporates Alpinestars Composite Stretch Plus (A-CS® Plus) material on the side torso and shoulder blades. This advanced material provides 20% additional elongation and increases tear resistance by 300% compared to traditional leather, all while being lighter and more breathable than leather accordion paneling. For optimal thermal management, the suit features extensive perforations on the upper chest, abdomen, and thighs, along with strategically placed, breathable Matryx® material panels for superior ventilation.
Protection is paramount, with the GP Plus v4 meeting Alpinestars’ professional racing standards. Technical safety features include:
-
Impact Armor: Race-proven GP-R elbow, forearm, knee, and shin armor, complemented by Nucleon Race shoulder armor.
-
Slider Protection: GP DFS shoulder, elbow, and knee sliders for superior abrasion resistance.
-
Tech-Air® Ready: Fully compatible with Tech-Air® 5 or Tech-Air® 10 Airbag Systems, including a dedicated forearm pocket for the Tech-Air® 10 remote LED panel.
-
Advanced Inserts: HRSF stretch inserts in the crotch, back of legs, inner arms, and pectoral areas for a tailored racing fit.
The interior is designed for endurance, featuring a detachable comfort liner treated with biostatic Polygiene® to keep the suit feeling and smelling fresh. Finished with soft stretch wrist and ankle cuffs, this suit offers the ultimate combination of professional-grade protection and all-day track comfort.
