Considering its specification sheet, this new machine should be even more of a beast than its predecessor, thanks in large part to a top-to-bottom rework of the previous powerplant. Internal engine updates include a 4mm-longer stroke that boosts displacement from 1352cc to 1441, camshafts with more duration and lift, polished cylinder-head ports, lighter forged pistons cooled by underside oil jets, a beefed-up crankshaft and revised fuel-injection settings. An all-new, catalyzer-equipped exhaust system features shaped and tapered header pipes. The last ZX-14 that Cycle World tested produced 163.7 hp and 103.7 foot-pounds of torque ("Turn & Burn," July, 2008; down from 170.2 hp and 103.8 ft.-lb. of the original '06 model).
