High levels of rigidity have been achieved by constructing the frame to be a very close fit around the motor, and for easy maintenance the right side of the frame can be unbolted. With no conventional steering head, fork tubes or triple clamps the omega chassis also allows greater freedom when mounting items such as the radiator, instruments and other front end components. And the name Omega? This was chosen because when viewed from the left side, the GTS1000's chassis resembles the Greek character Omega.

The GTS000's single-sided swinging arm front suspension consists of an aluminum swinging arm mounted to the main frame. A fully adjustable shock absorber is mounted between the swinging arm and frame. Arm steering inputs are transmitted from the handlebar crown through a steering box to a vertical cast aluminum spar (also called a knuckle arm) to the front wheel. This vertical spar is also supported by an upper arm mounted between the top of the spar and the main frame. Ball-joints located at the front of the swinging arm just above and below the axle and just below the steering box permit the front wheel and vertical spar assembly to turn left and right. This design offers the rider many benefits. Because the single shock is independent of the structure, which supports and steers the front wheel, its function is less influenced by the twisting and bending moments caused by braking and normal riding.

As a result this new front suspension system functions extremely well under a wide variety of road and load conditions to give excellent roadholding characteristics. Another advantage of this system is that it gave our engineers a large degree of freedom in establishing chassis dimensions. Depending on the location of the pivot points for the upper and lower arms, the length of the arms and the distance between the ball joints, the rate of change of rake and trail and other important factors could be changed to give the most appropriate dimensions. Another feature of this design is that the trail and wheelbase have very small rates of change during suspension action - the wheel moves in an almost vertical plane, thereby maintaining virtually constant steering characteristics regardless of suspension action. In addition, because there is almost no rearward movement of the wheel when the suspension is compressed our engineers have been free to locate the engine further forwards to achieve the desired front/rear weight balance. Finally, with its inherent anti-dive characteristics the GTS1000's front suspension eliminates the pitching motion experienced with conventional forks under braking to give a much smoother and more comfortable ride. Fully adjustable for spring preload, compression and rebound damping, the single front shock absorber offers 116 mm of wheel travel.

Developed from our proven and highly successful FZR1000 engine, the heavily modified GTS1000 engine has been specifically designed to produce significantly higher low to mid range torque with a smooth, stepless power delivery that is ideally suited to sport-tourer usage.

This has been achieved in a number of ways, and in particular by the use of Electronic Fuel Injection (EFI). Controlled by an Electronic Control Unit (ECU) the GTS1000's injection system delivers precisely the correct amount of fuel to each cylinder to suit the prevailing conditions. So whatever the altitude or ambient temperature, the engine 'jetting' is always right over a wide range of conditions - an especially important feature on a sport-tourer. In addition to these advantages, EFI also increases fuel efficiency and eliminates the need for a choke. Low to mid range. Performance has also been boosted by altering valve timing and lift, giving the GTS a strong spread of smooth pulling power. Together with the advanced suspension system, highly efficient fairing and ergonomically-designed riding position, this rider-friendly motor gives an incredibly smooth and relaxing ride.

The GTS1000's Electronic Fuel injection system consists of 4 injectors located in the machines inlet tracts, with each injector operated by an Electronic Control Unit (ECU). The ECU uses information gathered from sensors on and around the engine, including throttle sensor, intake air temperature sensor in the airbox, air intake pressure sensor in the inlet tract, an rpm sensor, water temperature sensor, cylinder identification sensor and oxygen feedback sensor. At low engine loads the precise quantity of fuel to be injected is determined by the amount of vacuum in the inlet tract, while at high loads it is determined by the amount of throttle opening. By independently monitoring each cylinder the exact amount of fuel is always injected which significantly improves throttle response and fuel efficiency over a wide range of operating conditions. So regardless of whether the GTS1000 is being ridden at sea level or high up in the mountains, in a very hot or very cold climate, the fuel mixture will always be accurate. And because Electronic Fuel Injection eliminates the need for a choke, the GTS is quick and easy to start whether the engine is hot or cold. Fitted with a self-diagnosis function, any potential problem on the new Electronic Fuel Injection system is easy to identify and put right.

As well as being remarkably smooth, the new GTS1000 powerplant is also cleaner than a conventional engine because it is filled with a 3-way catalytic converter. Used in conjunction with Electronic Fuel Injection this stainless steel honeycomb design catalyzer offers low flow resistance and reduces HC by approximately 60%, CO by approximately 70% and NOx by approximately 60%.

The GTS1000 represents many firsts for Yamaha, and with its 6-pot opposed piston caliper front brake it is the first production motorcycle fitted with this system. Operating a large, centrally-mounted 330 mm ventilated disc, this new caliper design ensures dependable braking, and is backed up by a 282 mm ventilated rear disc with twin pot caliper. New design 17 inch cast alloy wheels are fitted with a 130/60/17 front tire and 170/60/17 rear tire for excellent traction, and to accommodate the new single-sided swinging arm front suspension the front wheel axle is considerably offset.

The ABS system used on the GTS1000A is very similar to that used on the FJ1200A, and its advanced design incorporates an Electronic Control Unit (ECU) using dual microcomputers with a self-diagnosis function. A Hydraulic Unit (HU) controls the flow of brake fluid by means of a flow control valve, pressure control solenoid valve, buffer chamber, hydraulic pump and electric motor. The HU is controlled by the ECU which receives signals at 8 millisecond intervals from sensors at the front and rear wheels which it analyses using dual microcomputers. If the ECU senses imminent wheel lock-up it will signal the HU to increase and decrease brake fluid pressure at up to 10 times per second to prevent lock up at the relevant wheel The rider becomes aware of the ABS operation by feeling the pulsating brake fluid pressure at the front brake and rear brake levers. If the ABS system ever malfunctions a warning light is displayed on the instrument panel and the machine reverts to normal non-ABS assisted braking, Weighing only 2.8 kg, the HU for the GTS1000's ABS is located centrally in the chassis to maintain the low center of gravity achieved by this new machine.

As described in the introduction, one of our main aims when developing this revolutionary new sport-tourer was to offer the highest possible levels of rider and passenger comfort.

This has been achieved by the use of an aerodynamically efficient fairing, natural riding position and a luxurious seat, together with the GTS1000's excellent new front suspension system and our proven Monocross rear end.

We've also provided useful storage compartments for personal belongings, and fitted the machine with our most comprehensive instrument panel ever.

As every rider who has ridden at high speeds knows, comfort on a motorcycle is dramatically influenced by air velocity. The fairing and bodywork on the GTS1000 have been designed to manage the airflow in such a way as to minimize turbulence and maximize wind protection. Available as standard with a choice of sport or touring screens, the GTS fairing deflects turbulence and creates a relatively stable pocket of air around the rider and passenger. This extremely efficient design achieves a remarkably low coefficient of drag and also reduces wind and air noise induced fatigue. Built-in mirrors give extra weather protection for the rider's hands, and the tire-hugging rear fender keeps dirt and water in its place.

One of the most critical features for any long distance machine is the riding position. In Keeping wills our aim of producing an advanced sport-tourer we paid close attention to creating a seat/footrest/handlebar relations for the rider and a seat/footrest/rider relationship for the passenger that would ensure a natural riding position. Neither too far forward nor too upright, the GTS1000's riding position ensures high levels of comfort.

Long, roomy, deeply padded and comfortable, the dual seat allows the rider and passenger to shift their weight around and find the most comfortable position.

The GTS instrument panel is both elegant and functional, and includes a speedometer with twin trip meters, tachometer, clock, fuel gauge and a full range of indicator lights including one for water temperature. With its automotive style layout, the instruments are easy to read, and for high reliability and convenience both the speedometer and tachometer are electronically operated cable-free designs. Headlights throw a broad beam to give excellent forward and peripheral illumination, and for improved aerodynamics and enhanced looks both the front and rear turning signals are built in to the fairing and rear light cluster respectively. To deter thieves the GTS is equipped with a specially hardened 7-leaf tumbler ignition switch which resists attempts to penetrate it with drills and screwdrivers and should any attempt be made to by-pass the switch a sensor commands an automatic cut-out to immobilize the EFI.

Our proven Monocross suspension system is used at the back end for smooth, accurate operation. Created by a lightweight Deltabox swinging arm, the preload, compression and rebound adjustable shock gives a full 130 mm rear wheel travel for a comfortable ride even when fully loaded.

Another first on the GTS is our use of a new painting process developed by Yamaha. Called Melange, this patent-pending technique achieves an outstanding finish with amazing depth and clarity, and with its semi-metallic finish this new system emphasizes the high quality image of the new GTS1000.

The GTS1000 has been designed as an advanced sport-tourer and in line with this concept Yamaha has developed pannier boxes as optional accessory items. These panniers feature an all-new mounting system and have been developed in close co-operation with Krauser. They will be available exclusively as Genuine Yamaha Accessories through the Yamaha dealer network. The panniers will be available in two sizes with the larger version capable of storing an integral helmet.
