In 1981, Kawasaki throughly upgraded the KZ1000G to the KZ1000J model with a better engine and chassis, though they did go down in one specific number: displacement. By decreasing the bore slightly, they were able to get displacement to 998cc, which is what they needed to compete in AMA Superbike racing. Despite the slight displacement decrease, Kawasaki was able to get an almost 25% horsepower bump from the G to the J bike (83 to 102) thanks to a lighter crankshaft, lighter flywheel, larger valves, bigger (and lighter) aluminum 34mm Mikuni carbs, and a higher compression ratio.
The chassis got stiffer but lighter and it was paired with bigger forks and steeper rake. It worked – Eddie Lawson won the 1981 AMA National Superbike Championship with a factory KZ1000J, and that led to the famous ELR (Eddie Lawson Replica).
