The Kawasaki Versys 650, also known as the KLE650, is a middleweight motorcycle. It borrows design elements from dual-purpose bikes, standards, adventure-tourers and sportbikes; sharing characteristics of all, but not neatly fitting into any of those categories.〔(【引用サイトリンク】 title= 2010 Kawasaki Versys Review )〕 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.〔(【引用サイトリンク】 title= 2008 Kawasaki Versys - First Look )〕 A California emissions compliant version was released in 2009.〔(【引用サイトリンク】 title= Living With Versys-tility )〕 In 2010 new styling was applied to the headlight and farings and several functional changes made including enlarged mirrors and improved rubber engine mounts.〔(【引用サイトリンク】 publisher= topspeed.com )〕 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. 〔(【引用サイトリンク】 publisher= cycleworld.com )〕 ==Technical details== 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 at 8,400 rpm, compared with the Ninja's at 8,400 rpm.〔 Torque is , compared with the Ninja's .〔 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, 540 degrees) which gives the engine note a distinctive "throbbing" sound at idle.〔 The suspension has greater vertical travel and more adjustability than the suspension on the ER-6 / Ninja 650R. On the front the thicker/stronger 41 mm inverted front forks are externally adjustable for preload and rebound damping unlike the Ninja 650R/ER-6F's conventional and non adjustable forks. The right fork leg carries a damping cartridge while both legs contain springs. The rear shock absorber is adjustable for rebound damping. Suspension preload is adjustable in the rear via a screw collar on the shock. The rear shock/spring is directly connected, without linkages, to a non symmetrical, gull wing, aluminum swing arm instead of the more basic steel swing arm used on the Ninja and ER-6.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kawasaki Versys」の詳細全文を読む スポンサード リンク
