» 2007 Kawasaki Versys
The light in weight and feel 2007 Kawasaki Versys makes riding around town fun and easy. This do-it-all motorcycle combines a reassuring feeling with fluid response to your every action. The 399 lbs unique-looking machine features a compact engine, inverted front fork, slim upright riding position, adjustable windscreen, petal brake discs and sleek chassis.

When tuning 649cc parallel twin engine, the number one priority for the makers was to find a throttle response that combined a powerful feeling and a quick-revving character by maximizing the low-mid range torque, thus creating an extremely smooth and powerful engine character with high levels of control and great acceleration in the low and mid-rpm range. A balance tube in the exhaust system is used to achieve smooth power and torque curves. Intake and exhaust cams with short operating angles move the torque curve toward the lower end of the rpm range. Fuel injection settings for the 2007 Kawasaki Versys were selected mainly to deliver a strong powerful feeling when the throttle is opened. Even though performance was optimized for the mid-range (3,000-6,000 rpm), power delivery is smooth below 3,000 rpm and above 6,000. These settings make for a great performance at speeds most used for everyday riding (around 50-75 Mph).

Because of the triangular layout of the crankshaft and transmission shafts, the engine is fairly short front to back. The cassette-style transmission input shaft, output shaft and change drum make for a compact layout and easy maintenance. The plated, linerless cylinder is lightweight and the narrow cylinder pitch reduces engine width, while semi-dry sump design reduces engine height. Starting and warming up is simplified by an auto-fast idle system, which ensures the catalyzer reaches optimum temperature quickly. In addition, oil jets located in the rod big-ends direct oil to the undersides of the pistons for increased cooling. Coolant is routed through the engine cases to the cylinder and head via a simplified cooling system, which reduces external plumbing. A large radiator and under-engine muffler contribute to easier heat dissipation. The 2007 Kawasaki Versys features 180° crankshaft which drives a balancer shaft for extremely smooth engine operation. With its excellent corner pick-up, flat, step-free torque curve and smooth engine response, this motorcycle lets riders open the throttle with confidence at any rpm.

The compact parallel-twin engine allows for a sleek chassis and a slim, lightweight frame. Along with the front cowl, including instrument panel and headlight unit mounted directly to the frame, the forward-located seat position and under-engine muffler, the light engine-frame combination makes for a highly centralized mass distribution, which contributes to the highly nimble package; its high level of agility is also achieved through its tall seat height, long-stroke suspension and short wheelbase (55.7 inches) – the chassis dimensions provide a balance of flickability and high-speed stability. Even though the motorcycle’s performance is optimized for the 50-75 Mph speed range, it performs quite well at higher speeds as well. The engineers worked on achieving chassis settings, base frame construction and stiffness balance that would deliver a high level of feedback, thus better enabling the rider to recognize the bike’s limits.

With its long-travel front fork and rear shock, and 17" wheels the 2007 Kawasaki Versys was designed to handle aggressive sport riding and to be able to cope with any street conditions – from road imperfections such as bumps and potholes to unpaved streets and dirt roads. Riders also have the ability to consciously control the bike's front-rear weight transfer and balance with the help of the long stroke of the inverted front fork (5.9 inches) and off-set laydown rear shock (2 inches).

Increasing braking force on purpose to compress the front suspension before a corner reduces the caster, thus achieving quicker steering. Braking less aggressively will result in maintaining the bike's attitude and position for smooth, stable turn in. Versys’ performance is deemed best on relatively smooth roads, however it can easily handle any street riding conditions thanks to the combination of both long travel and stiff springs, which yields the benefits of off-road-style suspension as well as sport bike suspension; its excellent feedback enables aggressive sport riding and clearly communicates the bike's limits, increasing rider confidence. This is achieved by using a simple, lighter, non-link type rear shock which offers more direct feedback from the rear wheel. Fluent handling of road imperfections was a main goal with the 2007 Kawasaki Versys. The ability of the rear suspension to soak up bumps and ruts was the key to being able to ride over unpaved or paved, brick or cobblestone streets and imperfect roads, so a large amount of time and effort was devoted to the tuning of the Showa rear shock unit, which uses a free piston and 2-stage damping valves to ensure smooth action at the initial part of the compression stroke and firmer damping near full compression. The outer tubes of the 41 mm inverted front fork are tapered and relatively short, thus providing the perfect stiffness balance to complement chassis settings. To help reduce unsprung weight and to accommodate the longer stroke of the rear suspension, the makers chose an aluminum gulltype swingarm. Both the front and rear suspension have adjustable rebound damping and preload; the fork height is adjustable by 0.3 inches. The motorcycle’s quick steering is facilitated by the 17" wheels front and rear. Tire sizes are front: 120/60ZR17M/C 58W and rear: 160/60ZR17M/C 69W.

The makers of the 2007 Kawasaki Versys wanted to offer a comfortable, naturally relaxed posture and high controllability in an upright position so a great deal of time was devoted to fine-tuning the riding position, the key to which is the combination of a compact Parallel Twin engine and a narrow, lightweight trellis frame enabled by an offset laydown suspension. A short-style tank puts the rider closer to the front wheel for improved control and provides more choices of forward-rearward sitting positions. Freedom of movement is achieved through the seat’s slim design and the knee grip characteristics of the tank. The stepped shape of the two-piece seat provides support and comfort for the rider when accelerating. The wide, rubber covered footpegs are positioned low and slightly forward of the seat and complement the wide handlebar. The upright riding position, the long-stroke suspension and increased seat height combine to offer a great view of the road ahead. All of the above features make for a natural and relaxed riding position with a high level of control and freedom of mobility.

The adjustable windscreen features three different settings, each about 0.7 inches apart, allowing riders to suit the height according to their needs. An optional tall screen is also available. For those who enjoy longer trips, the 2007 Kawasaki Versys offers a full range of features to make travelling fun and comfortable – from the large volume fuel tank, excellent fuel economy and relaxed riding position to the adjustable windscreen and comfortable seat. A reinforced subframe was created to accommodate specially designed large-volume GIVI panniers and top cases, both of which are available as options and have the capacity to hold a full face helmet. The motorcycle’s profile can stay relatively slim even with the panniers attached thanks to the under-engine muffler.

The Versys is designed not only with the rider’s comfort in mind but the passenger’s as well. Each part of the two-piece seat was designed with different thickness and firmness of urethane for optimal comfort. Pillion position offers a relaxed seating posture, with the pillion grab bars located in a natural position and the heat kept away from the passenger. The layout of the bike allows for a passenger to be comfortably seated even when the panniers are attached.

The 2007 Kawasaki Versys is available in two colors: Ebony and Candy Burnt Orange. The stacked dual headlight with dual position lamps on the left and right gives the machine a unique appearance. On low-beam setting only the upper lamp lights up and both lamps are lit on high-beam setting. The instrument panel with a digital speedometer, analogue-style tachometer, digital fuel gauge, odometer and dual trip meter features white LED-backlighting for improved visibility at night. The turn signals function as hazard lights as well. Other features include LED taillight with clear lens, triple petal disc brakes for superb stopping power and under-seat storage space. The Versys is perfect as a commuter with an urban edge.
