A LEGENDARY KAWASAKI SUPERBIKE FROM THE GOLDEN AGE OF MOTORCYCLING!

Check out this legendary 1981 Kawasaki GPz1100, one of the most iconic high-performance Japanese motorcycles of the early 1980s! Before the Ninja revolution, Kawasaki's big-bore GPz machines were among the kings of the street, delivering massive four-cylinder horsepower, unmistakable styling, and serious superbike performance.

This is the original old-school, twin-shock GPz1100, featuring Kawasaki's legendary air-cooled inline-four engine, triple disc brakes, factory mag wheels, and classic superbike chassis.

This particular motorcycle also features a set of vintage Fox lay-down rear shocks, a desirable period performance upgrade!

Whether you're a Kawasaki collector, a vintage superbike enthusiast, or someone looking for a solid restoration project or a valuable parts donor, this GPz1100 deserves a closer look.

FROM A PRIVATE 23-MOTORCYCLE ESTATE COLLECTION

This motorcycle was acquired by Kaplan Cycles as part of a 23-motorcycle estate collection belonging to Mike, a longtime Connecticut motorcycle enthusiast and furniture business owner.

Mike had assembled an impressive collection of vintage Japanese motorcycles, including classic Hondas, Yamahas, and Kawasakis. He stored his motorcycles indoors in his large furniture warehouse, protected from the elements.

Sadly, Mike passed away before completing several of his restoration projects. His brother subsequently sold us the collection.

This GPz1100 was one of the motorcycles Mike intended to restore but never got around to finishing.

With approximately 240 motorcycles recently arriving at Kaplan Cycles and a substantial restoration backlog, we've decided to offer several of these vintage machines directly to collectors and enthusiasts rather than have them sit waiting for restoration.

This is your opportunity to purchase an increasingly collectible Kawasaki superbike in project condition and restore it yourself!

ORIGINAL SUPERBIKE CHARACTER & DESIRABLE COMPONENTS

For a motorcycle of this age that has been stored and awaiting restoration, this GPz1100 retains numerous valuable original components and period performance upgrades.

Notable features include:

• Legendary 1100cc-class Kawasaki four-cylinder engine: The iconic air-cooled superbike powerplant that helped establish Kawasaki's reputation for serious performance.

• Carburetor conversion: Originally equipped with electronic fuel injection, this motorcycle has been converted to carburetors by a previous owner.

• Vintage Fox rear shocks: Classic period-correct aftermarket lay-down shocks with restoration potential. The springs could be refinished and the shocks restored.

• Factory mag wheels: The distinctive Kawasaki alloy wheels remain installed.

• Triple disc brakes: Dual front discs and a single rear disc.

• Clean front end: Forks, front fender, headlight components, gauges, and front turn signals are present.

• Straight front fender: Appears to be in very good condition, an increasingly valuable original component.

• Fuel tank: Appears excellent externally, with no visible dents or damage noted. Interior condition has not been verified.

• Original-style instrument cluster: Gauges are present and appear to be in good condition.

• Frame: Appears straight, with no obvious evidence of collision damage or bent frame rails observed during our visual inspection.

• Engine cases: Main engine block appears to be in good external condition, although some covers are missing.

• Seat and tail section: Both remain intact, and the seat appears to be in good condition.

For those familiar with vintage GPz1100s, you already know how difficult and expensive certain original components have become to source.

The front fender alone can represent a significant replacement expense, with good examples potentially costing $200 or more. The gauges, tank, wheels, seat, engine cases, frame, suspension components, and other parts all have substantial restoration or parts value.

KNOWN MISSING COMPONENTS & PROJECT REQUIREMENTS

Please understand that this motorcycle is being sold as a non-running restoration project or parts bike. It is NOT a complete, ready-to-ride motorcycle.

Known missing components include:

• Clutch/engine side cover

• Countershaft/front sprocket cover

• One footpeg

• Rear turn signals

• Airbox or aftermarket pod filters

Additional hardware, components, maintenance, repairs, and restoration work may be required.

The fuel tank appears very good externally, but its internal condition has not been confirmed. The ignition key and fuel-cap operation have not been verified.

The engine has not been mechanically tested, and we are not making any claims regarding its running condition, compression, or internal mechanical condition.

The carburetor conversion was performed before our ownership, and its completeness and proper operation have not been verified.

What you see is what you get. We do not have any additional parts to include with this motorcycle.

EXCELLENT RESTORATION CANDIDATE OR VALUABLE PARTS DONOR!

There are two excellent possibilities for this classic Kawasaki.

RESTORATION PROJECT: For someone with the mechanical ability, time, and resources to restore a vintage Japanese superbike, this GPz1100 offers an excellent foundation. With its straight-appearing frame, good external tank condition, original-style components, and desirable Fox shocks, there is plenty here worth saving.

PARTS DONOR: If you're already restoring a GPz1100, you know how challenging it can be to locate good original components. This motorcycle offers a substantial collection of valuable parts in one package, including the engine, frame, suspension, wheels, fuel tank, gauges, seat, bodywork, and more.

These early GPz1100s represent an important chapter in Kawasaki's high-performance history. The original twin-shock machines are increasingly sought after by enthusiasts who appreciate the raw horsepower and unmistakable styling of the pre-Ninja superbike era.
