Product Details

An ultra-lightweight CE and UKCA certified protection jacket offering excellent upper body protection against impacts. This protector features an all-new Level 2 Cell Technology chest protector for ultralight weight and optimum ventilation. The super-ventilated Level 2 Nucleon Cell & Flex Hybrid Technology back protector is ergonomically engineered for an enhanced adaptive fit. Both the front and rear protectors are backed with a foam padding for a secure and comfortable snug fit.

The Alpinestars Honda Bionic Plus V2 Protection Jacket is designed for off-road riding with a strong balance of impact protection, airflow, and mobility.

What is your return policy

We offer a 45-day return policy for most products. Items must be in their original condition, unused, and with all packaging intact. Please refer to our Returns Policy page for more details on eligible products.

Why are some items heavily discounted

Many deals are last-season colors, overstock inventory, or discontinued models — not lower quality gear.

This is one of the smartest ways to score premium protection at a reduced price.
