The 2024 SR is the middleweight in the Zero naked street category and it’s the only motorcycle ever to be able to truly change with its rider. Available stock as an A2 licensed machine, the SR comes with an impressive 140 N-m of torque and 52 kW of power. The SR is also upgradable via a dealer installed firmware update that turns it into an even more capable full ‘A’ licensed machine, provided you meet the updated licensing requirements
