The 2020 Kawasaki Vulcan 900 Custom differs quite a bit from its other Vulcan 900 series brethren. While the engine, a 903 cc SOHC liquid cooled V-twin with 50 crank HP and 57 lbs-ft of crank torque, is the same, the rest of the motorcycle has a variety of differences.
The frame is slightly lower and the seat moved a bit further back, as well as the floorboards being replaced with forward-mounted footpegs. The standard handlebars are replaced with raked back drag handlebars, and the exhaust is a parallel slash cut straight pipe style. Lastly, the 900 Custom is almost entirely blacked out, except for aggressive pinstripes and some contour lines highlighting the muscular stance of the bike.
The 2020 Vulcan 900 Custom starts at $8.499 US/$10,199 CA

2020 Kawasaki Vulcan 900 Custom Features
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.
