2023 Moto Morini Seiemmezzo STR 650
 
Urban Style. Italian Engineering. Built for the Ride.
 
The 2023 Moto Morini Seiemmezzo STR 650 is the streetfighter of the lineup — clean, confident, and designed to dominate the daily ride with smooth performance and head-turning Italian aesthetics. As the stripped-down, purest version of the Seiemmezzo series, this STR offers everything you need and nothing you don’t.
Powered by a responsive 649cc parallel-twin engine, the Seiemmezzo STR delivers the perfect balance of punchy torque and everyday rideability. With premium components like KYB suspension, Brembo brakes, and full LED lighting, this naked sport bike feels more high-end than its price tag suggests.
This version does not include the optional Sport Package, making it ideal for riders who want to personalize their ride or keep things simple and clean right out of the gate.
