The Kawasaki Versys 650 (codenamed KLE650) is a middleweight motorcycle. It borrows design elements from dual-sport bikes, standards, adventure tourers and sport bikes; sharing characteristics of all, but not neatly fitting into any of those categories. The name Versys is a portmanteau of the words versatile and system. It was introduced by Kawasaki to the European and Canadian markets as a 2007 model and to the US market in 2008. A California emissions compliant version was released in 2009. In 2010 new styling was applied to the headlight and farings and several functional changes made including enlarged mirrors and improved rubber engine mounts. In 2015, a new model was introduced with a new fairing style that abandoned the older, stacked headlights for the more conventional twin headlight style commonly found on sportbikes.
The Versys is based on the same platform as Kawasaki's other 650cc twin motorcycles, the Ninja 650R and the ER-6n. It shares the same electronics, engine, wheels, brakes and main frame as its siblings. Where it differs is in riding position, rear sub frame, suspension components, and engine tuning.
The Versys' 650 cc liquid cooled, four-stroke, parallel-twin engine has been retuned for more bottom-end and mid-range torque. This is achieved with different camshafts and fuel injection mapping. These changes cause peak torque to occur at a lower engine speed and provide better throttle response in the 3,000 to 6,000 rpm range. In addition a balance tube has been added between the exhaust headers to smooth out power delivery. Power is 59.4 hp (44 kW) at 8,400 rpm, compared with the Ninja's 65.7 hp (49 kW) at 8,400 rpm. Torque is 42 lb⋅ft (57 N⋅m), compared with the Ninja's 45.5 lb⋅ft (61.7 N⋅m). Improving the engine's low and mid range response comes at the expense of a slight reduction in peak power however. A similar approach was recently deployed by Honda with their CBF1000 model. The engine uses a 180 degree crankshaft. This in turn requires an uneven firing interval (180 degrees, 360 degrees) which gives the engine note a distinctive "throbbing" sound at idle.
