Product details
- GP Plus R v4 RIDEKNIT® Leather Jacket is optimized for superior freedom of movement and rider comfort, and features extensive race-derived features and materials including a dedicated ‘Sport’ fit with pre-curved arms for maximum riding performance, and race-proven protection on shoulders and elbows
- Alpinestars composite stretch technology, A-CS® Plus, stretch panels on the torso for exceptional breathability, comfort, and freedom of movement, as well as delivering a lighter weight and a lower profile than a traditional leather accordion panel (the A-CS® Plus panels are about nine percent lighter than leather panels). Another key advantage of using A-CS® Plus is its superior stretch performance; A-CS® Plus has about 30% elongation, and offers an increase in tear resistance of 300% compared to HRSF (Hyper Resistant Stretch Fiber), and an increase in cut resistance by 600% versus leather
- 1.3 mm ‘Race’ grade leather construction for optimum blend of abrasion resistance and comfort
- RIDEKNIT® engineered inner arms; RIDEKNIT® combines high abrasion and tear resistance with high flexibility, comfort and mechanical stretch while still delivering superior comfort and high levels of breathability
- Extensive technical stretch panels under the arms, on the inner arms, and around the neck for an optimized fit. Dual density DFS shoulders for superior friction control
- GP Lite elbow armor for impact protection in a key area

Authorized dealer, genuine parts
Every part is sourced directly from the manufacturer or their authorized distributor — this one from ALPINESTARS.
Motorcycle parts are model specific and the same part often changes between model years. If you are not certain this one fits, ask us first — it takes a minute and it saves a return.
- Send the bike. Year, make, model and trim — for example “2021 Suzuki GSX-R750”.
- Send the VIN if you have it. It removes any doubt about a mid-year running change.
- We confirm before you order. A technician at the dealership checks this part against your bike. No charge, no obligation.
