How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's best suited to spirited road riding and moderate-distance touring, blending Katana styling with air-cooled four-cylinder performance rather than outright track ambition.
- Built for
- It has the character of a classic early-80s sport-standard: a torquey, air-cooled DOHC four delivering smooth, linear power with a distinctive shaft-drive feel and iconic angular Katana styling.
- Not ideal for
- It's not ideal for riders seeking modern lightweight agility, off-road capability, or cutting-edge sport-bike cornering performance.
