Kawasaki Zephyr 1100
The Kawasaki Zephyr 1100 has a top speed of 210 km/h (estimated; note: factory limited/varies by market), produces 89 hp and weighs 228 kg. Motoryk rates it 7.5/10.
The Kawasaki Zephyr 1100 (ZR1100) was introduced in 1992 as part of Kawasaki's retro-styled Zephyr lineup, which aimed to capture the classic naked bike aesthetic of the 1970s air-cooled inline-four era. It was the largest of the Zephyr family, sitting above the Zephyr 550 and 750, and used a refined version of Kawasaki's proven air-cooled 1052cc engine. Production continued until 1997, and it remains notable as one of the most celebrated retro-naked bikes of the early 1990s, beloved for its classic styling combined with strong real-world performance.

What Buyers Should Know
Proven Engine Reliability
The Zephyr 1100 uses a carbureted inline-four engine derived from the proven ZX-11, known for longevity when properly maintained. Well-kept examples regularly surpass 80,000 miles with minimal issues.
Watch the Carbs
The four Keihin carburetors are prone to gumming and jetting issues if the bike sits unused, so always inspect for smooth, consistent throttle response and clean fuel delivery before buying.
Strong Retro Resale
As a classic naked retro bike from the early 1990s, the Zephyr 1100 holds steady collector appeal and prices have been gradually climbing, making well-maintained examples a solid long-term buy.
Generations & Specs by Year
Original release; air-cooled inline-four, classic retro styling, no significant mid-cycle updates throughout production run.
"Honest retro muscle with no pretense whatsoever."
The Zephyr 1100 never pretended to be something it wasn't — it's a big, heavy, air-cooled bruiser that pulls hard from around 3,500 rpm and sounds genuinely mean doing it. Kawasaki dressed up their GPz1100 engine in classic chrome and round gauges, and the result is a bike that feels substantial in a way modern retros with their LED tricks simply don't. The weight is real — 238 kg is noticeable at slow speeds and parking lot maneuvers will remind you of it daily — and the front brake is softer than you'd want for a machine this heavy. But get it out on an open road, crack the throttle in third, and the Zephyr rewards you with that old-school inline-four surge that no amount of ride-by-wire can replicate.

Used Buyer Review
"A no-nonsense torque machine that rewards patient, informed buyers."
$2,500-$5,500 usedThe Zephyr 1100 is one of those bikes that quietly earns your respect. Kawasaki built it from 1992 to 1997 as a straightforward naked roadster, and that simplicity is exactly why it still makes sense today. The air-cooled inline-four pulls hard from low revs and sounds genuinely mean without trying too hard. It's not a sport bike pretending to be retro — it's just a proper motorcycle that does what you ask. Buying used, watch the carbs closely. Four Keihin CVs sitting unused go gummy fast, and a full carb rebuild will cost you real money at a shop. Check the fork seals, inspect the original air filter box (many have been replaced with pods, which kills midrange), and look for rust in the tank. Mileage matters less than maintenance history on these — a 40,000-mile bike with receipts beats a 15,000-mile mystery machine every time. For the money, there's genuine character here. It's not the fastest or lightest option, but it's honest, torquey, and looks right without being precious about it.
