Alpinestars Bionic Action V2 Motocross Protection Jacket - High shell

In this review the Alpinestars Bionic Action V2 is evaluated as a lightweight, high-ventilation protection jacket aimed at riders who prioritize cooling and mobility without sacrificing certified impact protection. The jacket's standout trait is its exceptionally perforated shell and perforated protectors, which deliver continuous airflow during aggressive riding. It is CE and UKCA certified with Level 2 protectors front and rear, so the primary reason to buy is the combination of genuine high-impact resistance and superior breathability for long, hot sessions on trail or track.

Key Features

• Highly perforated shell: The extensive perforation provides strong ventilation to keep the upper body cool during hard efforts and sustained rides.
• Cell Technology back protector: The Level 2 Cell Technology back protector with a flexion channel improves mobility and follows natural spine movement while still delivering certified impact protection.
• Perforated protectors: Both chest and rear protectors are ventilated to reduce heat buildup and promote continuous airflow against the body.
• Elastic closure system: Quick buckles and adjustable elasticated straps enable fast, tool-free fitting that accommodates a broad range of rider sizes.
• Padded chassis: Internal foam padding produces a snug, close-to-body fit that increases comfort and keeps protectors properly positioned during motion.

Who It's For

The Bionic Action V2 suits motocross and enduro riders, as well as mountain bikers who want certified Level 2 upper-body protection with minimal weight and maximum airflow. Its ventilation and lightweight construction make it especially useful for hot climates or high-exertion days when overheating is a concern.

Riders who need a roomy or relaxed fit should look elsewhere, because multiple users report that sizing runs small and the jacket delivers a close-to-body fit by design. If you require integrated hydration or heavy winter insulation, this ultra-ventilated protector is not the right choice.

Pros & Cons

Pros

• Excellent ventilation from a highly perforated shell and perforated protectors for comfort in hot conditions.
• High-impact Level 2 front and rear protection with foam-backed units for a secure, comfortable fit.
• Lightweight construction that reduces rider fatigue and is suitable for long sessions.

Cons

• Sizing runs small according to multiple customers, so ordering one size up may be necessary.
• Designed for ventilation and mobility, so it lacks insulation or integrated cold-weather features.
