1983 Kawasaki reviews

1983 Kawasaki GPZ1100 Review The 1983 Kawasaki GPZ1100 is a legendary machine that marked a significant milestone in the evolution of superbikes. With its bold red color and sleek design, it was a head-turner right from the start. But the GPZ1100 was more than just a pretty face; it was a powerhouse on wheels. Performance and Engine: Under the hood, the GPZ1100 packed an air-cooled, fuel-injected, DOHC 1089cc inline-four engine. This beast delivered impressive power, thanks to several top-end changes introduced in 1983. The combustion chamber was redesigned to a polyspheric shape, allowing for larger valves and a higher compression ratio of 9.5:1. The result? More power and better performance1. The engine’s straight-cut primary drive and five-speed transmission ensured smooth power delivery, making the GPZ1100 a joy to ride. The bike’s midrange power was particularly noteworthy, providing a smooth and responsive ride without the abrupt rush of top-end power seen in some competitors2. Handling and Suspension: Kawasaki equipped the GPZ1100 with advanced features for its time, including anti-dive forks and a single-rear-shock suspension. These race-proven components contributed to the bike’s stable and predictable handling, especially at high speeds. However, some riders found the handling a bit heavy at lower speeds, a trade-off for its high-speed stability. Design and Comfort: The GPZ1100’s design was both functional and stylish. The frame-mounted half fairing, sweeping lines, and red wheels with polished aluminum highlights gave it a distinctive look. The cockpit was designed for functionality, offering a comfortable riding position for long journeys. Legacy: The 1983 GPZ1100 was Kawasaki’s statement of intent in the superbike arena. It was a bike that combined power, style, and advanced technology, setting a benchmark for future models. While it faced stiff competition from Suzuki’s GS1100 and Honda’s CB1100F, the GPZ1100 held its own and remains a beloved classic among motorcycle enthusiasts. Whether you’re a fan of vintage bikes or just appreciate a well-engineered machine, the 1983 Kawasaki GPZ1100 is a testament to Kawasaki’s commitment to performance and innovation. Show less

This bike is a real sleeper. The engine performance is unreal. The bike is totally restored with everything that can ware new. Totally disassembled and painted with red and silver House of Kolor flake with eight coats of PPG 220 speed clear. Due to the increased displacement of 1410cc, the fuel injection has been reprogrammed, larger adjustable pressure regulator and larger injectors. 11.5:1 compression with Weisco pistons. Web cams, lightened crank, close ratio gears, the works. Over 200HP. A real Busa tormentor. Show less

Picked her up a couple of years ago rotting in a yard. She's now completely redone back to stock except for the paint scheme. Out of all the bikes I've rebuilt, this remains my favorite. Incredibly powerful motor for the time and even still by today's standards. Not great handling or power at low throttle but roll it on and look out, she keeps coming, willing to play at any level you want to go to. Give her another five years and she'll match the 73 Z1 in value as well. Far and away one of the best street bikes Kaw ever made. Show less

I bought a 83 with a 84 motor. The motor is not stock 12:1 compression head work doen wisco pistons etc. Est about 170hp. It smokes the area zx11s. I love it guys will think ah that thing is nothing its old. Yes its old but it's all motor. I smoke them every time. Mostly they keep on ridding or turn off in embarrassment. I am working on the handling package and looking for a Fork Brace still. The motor is good but the suspension needs updating big time it gets squirrelly on a 100mph turn. Anyhow everything else is working computer fuel injection. It's a great bike. The only complaint is it has vibrations of a 600. Show less

Recently purchased the GPZ1100 - 1983 and am quite impressed with its more than medium handling and early big block punch. Also, I am more than impressed with its technology of its time - i.e.: many built in safety features. Have ridden many new machines but this one is still worth considering - but this one is still one for the collection! It is a good, strong, fast comfortable bike - worth the going price - if its a good one!! Show less

I'm in agreement with Carl. I bought my bike 3 years ago and I didn't have any problem since that time. That bike don't look as old as [it] is. Show less

Never a problem, and as much power as expected for a 550. This is one trouble free bike I've had for many years. Show less
