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.
