Reviews & Tips
1. A-CS Plus composite stretch panels provide increased stretch, improved breathability, and lighter weight than leather accordion panelling — a meaningful real-world advancement
2. DFS shoulder sliders with Nucleon Flex Plus Level 1 and GP-R Lite extended elbow armor deliver comprehensive CE AA certified protection
3. Detachable 80g thermal vest and abdominal ventilation vents provide practical climate management across a range of conditions
1. At £499.99 it’s a premium investment that earns its price primarily through regular sport and track riding use
2. Race-fit pre-curved construction is optimised for the riding position — less comfortable as a standalone jacket off the bike
3. A-CS Plus panels may require different care instructions than standard leather — check before washing
The GP Plus V4 is a complete revolution over the V3 rather than simply an evolution. The introduction of A-CS Plus composite stretch material in the large side panels is the defining change — a MotoGP-derived technology that provides increased stretch, high abrasion and tear resistance, a lower profile, and lighter weight than leather accordion panelling, all in a material that also delivers higher breathability. Combined with race and regular bovine leather on the main chassis and tech stretch material on the chest, shoulders, back of neck, and inner arms, the V4 is a significantly lighter and more breathable jacket than the V3 it replaces.
DFS Dynamic Friction Shield external shoulder sliders come with Nucleon Flex Plus CE Level 1 armor underneath, and GP-R Lite extended elbow armor provides impact protection with pre-curved race fit comfort. A detachable thermal vest (80g) and long direct-opening ventilation vents on the abdomen handle climate management across a range of conditions. Tech-Air Ready compatibility allows airbag system integration, and internal pockets accommodate optional protection upgrades. CE certified to Category II EN17092-3:2020 AA Class.
The GP Plus V4 is aimed at sport and track road riders who want a race-derived leather jacket with significantly improved breathability and freedom of movement over traditional leather alternatives. At £499.99, it’s a premium mid-range leather jacket investment for those who ride on road and track and want the benefits of A-CS Plus material technology.
