No cruiser has ever displayed more "bad boy" attitude than the Kawasaki Vulcan® 1500 Mean Streak® motorcycle – except the newer 2004 Vulcan 1600 Mean Streak. The 2004 Vulcan 1600 Mean Streak has all the long, low, hot-rod-inspired styling and sportbike handling of its predecessor, but its large 1,552cc V-twin engine packs a bigger punch. New pistons and modified cams improve performance for low rpm starts and mid-range bursts for those all-too-rare passing lanes. And since looking good is as important as performance, Kawasaki gave the new 1600 Mean Streak some extra grooming, including new valve covers and reshaped cooling fins. To give the 1600 Mean Streak more power, piston stroke has been increased by 5mm, boosting displacement from 1,470 to 1,552cc. Cam angle, lift and valve timing are also changed to improve low- and mid-rpm performance.
