Reviews & Tips
1. Enduro-oriented chamois padding provides specific riding comfort for the body positions and saddle contact patterns of enduro and off-road riding, rather than using a road-cycling chamois that doesn’t suit the MX riding position
2. Polygiene Biostatic Stays Fresh Technology inhibits bacterial growth and odour over multiple wearing sessions — a practical feature for multi-day enduro events or back-to-back training days where washing between sessions isn’t always possible
3. Stretchable lower thigh hem provides specific compatibility with knee braces, preventing the shorts from binding against knee brace straps during the full range of leg movement
1. At £119.99, the Bionic Pro sits above the Bionic Action Protection Shorts, with the chamois, Polygiene tech, and knee brace compatibility justifying the difference for the right rider
2. CE and UKCA Level 1 certification covers the hip protection zones; riders who need Level 2 lower body protection will need a more premium solution
3. The enduro chamois makes these specifically optimised for enduro and off-road riding; road or circuit riders may find a different chamois profile better suited to their riding position
The Alpinestars Bionic Pro Protection Shorts share the core foundation of the Bionic Action — CE and UKCA Level 1 certified hip protection, breathable mesh construction, crash-data-informed padding placement — but are specifically tuned for the enduro and off-road riding environment rather than general motorcycle use. The three additions that differentiate the Pro are practical and purposeful: an enduro chamois, Polygiene Biostatic technology, and knee brace compatibility.
The enduro-oriented chamois pad distinguishes the Pro from general-purpose protection shorts immediately. Enduro riding involves a different relationship with the saddle than road or circuit riding: more standing time, more dynamic saddle contact during technical sections, and a generally more upright body position than aggressive road race positioning. An enduro chamois is profiled and positioned for this specific riding style, providing comfort in the areas that matter most for enduro saddle contact without the road-cycling optimisation that doesn’t translate to off-road riding.
Polygiene Biostatic Stays Fresh Technology is integrated into the fabric construction. The technology inhibits bacterial growth and the associated odour that develops in protection shorts after multiple wearing sessions, extending the effective fresh-wearing life of the shorts between washes. For multi-day enduro events, stage races, or riders who train multiple days in succession without wash access, this is a genuinely practical feature rather than a marketing specification.
The CE and UKCA Level 1 hip protection uses a two-part slip-joint overlapping construction where the protector meets the stretch mesh chassis. The overlapping design allows the hip protector to flex relative to the chassis during body movement, providing continuous hip coverage without creating the rigidity that a single-piece connection would impose on the joint area. Strategically positioned padding covers additional impact zones identified from crash-pattern analysis.
The stretchable lower thigh hem is the final targeted feature: designed specifically to be compatible with knee braces, the hem doesn’t bind against brace straps during the full range of leg movement that enduro riding demands.
The Bionic Pro Protection Shorts are for enduro and off-road riders who want CE and UKCA Level 1 certified protection shorts engineered specifically for the enduro riding environment. The enduro chamois, Polygiene technology, and knee brace compatibility make these the right choice for riders who compete or ride extensively in enduro, stage racing, or technical off-road disciplines where these specific features make a practical difference.
