Key Features

  • BREMBO FRONT BRAKES: Get excellent stopping power, with better bite and greater rider control with the Street Twin’s 4-piston Brembo front brake caliper.
  • CARTRIDGE FORKS: Higher specification 1.6 inches (41mm) cartridge forks offer 4.7 inches (120mm) travel for a more comfortable and confident ride.
  • FIRST-IN-CLASS RIDING MODES: To the Street Twin, and first in class, Road and Rain riding modes adjust the throttle map and traction control settings for more riding control, via a dedicated mode selection button incorporated into the bike’s left hand switchcube.
  • TORQUE-ASSIST CLUTCH: It’s easier to enjoy your Street Twin ride for longer with a torque-assist clutch that’s optimized to reduce the rider’s clutch lever effort, especially during stop/start urban rides. The resulting reduction in clutch packaging also facilitates a narrower engine.

  • ABS & SWITCHABLE TRACTION CONTROL: Latest generation ABS and switchable traction control manages the Street Twin’s thrilling torque when it’s required. Compact, responsive, and incorporated with minimal visual impact, these contemporary safety standards can maximize rider safety.

  • ENHANCED COMFORT & RIDER ERGONOMICS: Already renowned for its confidence inspiring accessible ride, this Street Twin delivers even better rider ergonomics and comfort, courtesy of a revised riding position and improved seat construction.
  • CAST WHEELS: Cast aluminium alloy multi-spoke wheels with machined detailing, fitted with Phantom Sports Comp tires for capability and durability.
  • ICONIC PREMIUM STYLING: Even more contemporary finishes and detailing combine to give the Street Twin an added level of premium quality.
