The Alpinestars GP Tech v4 Leather Suit is a race-focused one-piece motorcycle suit designed for riders who demand lightweight performance, advanced protection, and unrestricted movement on the track. This black and white suit is sized US 40 / EU 50 and features a highly pre-curved race fit through the body, arms, and knees for an optimized riding position. Kangaroo leather is positioned through high-flex areas including the arms, hips, and abdomen, while race-grade bovine leather supports durable protection in key zones. The result is a balanced construction that reduces weight without compromising abrasion resistance or comfort.
The GP Tech v4 uses MATRYX® structural panels across the thighs, abdomen, chest, and back hump for advanced ventilation, mechanical tear resistance, and abrasion protection in a thin, lightweight package. MATRYX® lower-leg panels are covered with high-performance polyurethane and derived from MotoGP development to improve airflow, flexibility, and freedom of movement. Extended stretch panels at the chest, inner arms, crotch, and back of the legs further improve mobility and comfort. Strategic perforations on the arms and legs help regulate airflow, while the Cool-iR treatment reflects infrared energy to reduce heat buildup inside the suit.
Protection includes GP DFS armor for impact and abrasion resistance with controlled friction performance, replaceable elbow sliders, internal Race-spec GP-R Lite armor, and Bio-Flex Race hip armor. The suit is Tech-Air® ready and accommodates the Tech-Air® 10 Airbag System with extended hip protection, sold separately. A dedicated left-forearm slot provides space for the Tech-Air® 10 wireless LED display. An internal paddock waist hook system helps keep the suit positioned when moving around the pit area with the upper portion resting off the shoulders.
For convenience between sessions, the detachable short-leg comfort liner includes Polygiene® treatment for long-lasting freshness. The Alpinestars GP Tech v4 Leather Suit is supplied under manufacturer and vendor part number 3156822-12-50. It is intended for motorcycle racing and track use, providing a performance-oriented fit and integrated protection for riders seeking a premium race suit from Alpinestars.
