ENGINE
When tuning the 649 cm³ Parallel Twin engine, our engineers' first priority was to find a throttle response that balanced a powerful feeling and a quick-revving character. To optimise performance for everyday riding (most of which takes place in and around the 50-75 Mph (80-120 Kph) range), care was taken to maximise low-mid range torque. When opening the throttle, riders will notice that the engineers succeeded in creating an extremely smooth and powerful engine character that offers both a high level of control when making minute throttle adjustments and a gratifying rush of acceleration in the lower rpm ranges.
* Intake and exhaust cams with short operating angles move the torque curve toward the lower end of the rpm range.
* To achieve smooth power and torque curves, the exhaust system makes use of a balance tube.
* Fuel injection settings for the Versys were selected primarily to deliver a strong powerful feeling when the throttle is opened.
* Performance and feel were optimised for the mid-range (3,000-6,000 rpm). However, in the low-rpm range (below 3,000 rpm), power delivery is very smooth, and even above 6,000 power and torque curves continue on without dropping off suddenly.
* The above settings result in a performance that favours speeds most used in everyday riding: the range in and around 50-75 Mph (80-120 Kph). Corner pick-up is excellent: the powerful mid-range delivers a satisfying surge of acceleration and the flat, step-free torque curve and smooth engine response let riders open the throttle with confidence - at any rpm.
* Triangular layout of the crankshaft and transmission shafts makes the engine very short front-to-back.
* Transmission input shaft, output shaft and change drum are contained in a "cassette"-style package that both allows a compact layout and facilitates transmission maintenance.
* Semi-dry sump design reduces engine height.
* Plated, linerless cylinder is lightweight, and the narrow cylinder pitch reduces engine width.
* Auto-fast idle system simplifies starting and ensures the catalyse ...
