In the rear, the Kayaba shocks used the same springs, but with greater pre-load, and the compression damping was effectively doubled. The fork had slightly stiffer springs, and compression and rebound damping were increased approximately 10%. The suspension calibration was all-new for 1982, to make the big GPz an even better handler both on the track and on the street. The new system did not use an airflap to measure airflow, but a digital microprocessor, a series of sensors, and a throttle position sensor to meter the fuel much more accurately, eliminate throttle lag, and decrease emissions. The early BOSCH-type open-loop analog fuel injection was scrapped, and a new closed-loop digital fuel injection (DFI) was used in its place. The engine output was increased by increasing the valve lift from 8.3 mm to 8.7 mm, and valve duration was increased from 280 degrees to 288 degrees to boost upper-end horsepower. Kawasaki was serious about having the best Superbike, and the B2 was changed in several significant ways over its predecessor. The B2 featured a cockpit fairing, the use of LCD warning lights and improved engine coating using a black chrome finish instead of the previous black paint. It weighed 255 kg (562 lb) with a full tank of fuel, and the power output was claimed to be 108 bhp (81 kW). To reduce weight, the tube walls were thinner. Suspension and braking was similar to earlier models the front forks featured 38 mm tubes, the frame design, based on the 1981 J model, was made from larger diameter steel in the section between the steering head to rear of the tank. Rather than featuring carburetors, the B1 was fitted with electronic fuel injection (EFI) a Bosch-derived Nissan fuel injection as used on the earlier 1980 Z1000G/H models. Cycle World stated '.the big Kawi went well, with standing quarters in just over 11 seconds at 119mph, fastest in its class at the time.' Its frame design was a typical cradle design and the engine was based on the new z1000J motor, fitted with roller bearings, but the engine capacity was increased to 1,089 cc. It was officially marketed as the GPz1100 B1. The 1981 GPz1100 was the first 1,100 cc motorcycle released by Kawasaki.
