The 2021 Kawasaki Vulcan 900 comes in three sets of clothing: The bare, raw 900 Classic, a city cruiser through and through; the 900 Custom, an expression of American custom style from Japanese manufacturer; and the 900 Classic LT, which is designed for the longer distance touring style of cruising.
All are powered by a liquid-cooled 903cc V-twin, which chucks our 50 HP and a gutsy 57 lb-ft of torque. All power the rear wheel through a kevlar-reinforced belt-drive system. The 900 Classic features tank mounted instruments, rider floorboards with heel and toe shifters, and a pillion cushion for a passenger. The 900 Classic LT, which stands for Light Touring, adds a pillion backrest, leather saddlebags, seat studding, and a full touring windshield.
The 900 Custom is where Kawasaki designers and engineers took a bit of liberty to have a little fun. Low and pulled back drag bars give the bike a more aggressive look, as do the forward mounted pegs replacing the floorboards. The bike also gets a set of loud, parallel slash-cut exhaust pipes in matte black, and pinstripe wheels. It also gets a classic American teardrop tank.
The 2021 Kawasaki Vulcan 900 Classic starts at $8,199 USD / $10,199 CAD, the 900 Custom starts at $8,699 USD / $10,399 CAD, and the 900 Classic LT starts at $9,199 USD / $11,749 CAD.

Dual Throttle Valves
Late-model sport bikes often use large-bore throttle bodies to generate high levels of power. However, with large diameter throttles, when a rider suddenly opens the throttle, the unrestricted torque response can be strong. Dual throttle valve technology was designed to tame engine response while contributing to performance.
On models with dual throttle valves, there are two throttle valves per cylinder: in addition to the main valves, which are physically linked to the throttle grip and controlled by the rider, a second set of valves, opened and closed by the ECU, precisely regulates intake airflow to ensure a natural, linear response. With the air passing through the throttle bodies becoming smoother, combustion efficiency is improved and power is increased.
