The 1999 Intruder's 45-degree V-twin engine produces an incredible amount of low-end and mid-range torque. That lets you pull away from stoplights with a strong surge of acceleration, or pass traffic safely on a two-lane road with a twist of the throttle. On the open highway, you'll find the Intruder 1400 exceptionally smooth, thanks to the engine's staggered crankpins, rubber engine mounts and shaft drive. The longer you own your Intruder 1400, the more you'll appreciate its advanced technology. Each cylinder has a single overhead cam with three valves for efficient operation. Air-oil cooling ensures consistent performance hour after hour.
