Although the Kawasaki VN900 Custom's SOHC, 55-degree, V-twin is just 903cc
the amount of torque and power delivered belies those small dimensions. The
Kawasaki VN900 Custom's gearchange is snickety smooth and there’s a decent
amount of grunt up to 3000rpm. Beyond 3500 the Kawasaki VN900 Custom engine
loses some of its pep, but at cruising speeds, even when the speedo reads 75,
buzz is absent and the Kawasaki VN900 Custom continues to deliver a silky-smooth
ride.
