NO RESERVE AUCTION SALE = HIGH BIDDER WINS

DOES NOT RUN ~ AN EXCELLENT WINTER PROJECT

22,375 Miles, Original Four-Cylinder Engine, Professionally Restored Fuel Tank & Side Covers, Factory Original Four-Pipe Exhaust, Clean Title, A Highly Collectible Japanese Classic!

Kaplan Cycles is proud to offer this beautiful 1975 Honda CB750 Four K5, one of Honda's most legendary motorcycles and a true cornerstone of Japanese motorcycling history!

This particular CB750 was the crown jewel of a 23-motorcycle collection recently acquired from the estate of our late friend Mike, a passionate vintage motorcycle enthusiast who appreciated the timeless beauty and engineering of these classic Hondas.

Mike had already invested considerable money into professionally restoring the fuel tank and side covers, giving this motorcycle a tremendous head start toward a complete restoration.

With its gorgeous refinished bodywork, remarkably well-preserved original components, and clean title, this CB750 represents an outstanding opportunity for a collector, restorer, or vintage Honda enthusiast.

HIGHLIGHTS & FEATURES

PROFESSIONALLY RESTORED FUEL TANK & SIDE COVERS

One of the most impressive features of this CB750 is the exceptional condition of its professionally restored fuel tank and matching side covers.

The previous owner spared no expense having these components refinished. The tank features beautiful paintwork, fresh decals, and replacement lower trim. Both side covers Look New and present beautifully.

Anyone who has restored a vintage Honda CB750 knows how expensive it can be to have it refinished to this standard.

We estimate that replacing a comparable professionally restored tank and side-cover set could cost approximately 1,700–2,000.

That work has already been completed, saving the next owner considerable expense and effort.

Please note that the fuel tank cap was misplaced during the estate move and will need to be replaced. Reproduction and replacement caps are available through vintage Honda parts suppliers.

EXCELLENT ORIGINAL COMPONENTS

What makes this CB750 particularly desirable is the number of original factory components that have survived in good condition.

The original seat is exceptionally well preserved, with upholstery that presents beautifully for a motorcycle more than 50 years old.

The factory chrome rear fender and grab bar are in excellent condition, and the front fender, fork lowers, and suspension components also present well.

The original four individual exhaust pipes remain installed, an important feature on these vintage CB750 Fours. The pipes are not perfect, and their internal baffles have been removed, and they have some rust, but all four are intact.

Original four-pipe exhaust systems are increasingly desirable because so many CB750s were modified over the decades with aftermarket four-into-one systems.

The original wheel chrome has patina but looks good overall, although the spokes have been cosmetically touched up with paint.

There is no visible evidence that this motorcycle has suffered significant crash damage, but it was dropped in the driveway and the left side engine cover has some road rash on the bottom side from a low speed drop.

The motorcycle retains its factory identification tag, which shows a June 1974 manufacturing date, consistent with early production for the 1975 model year.

ENGINE & MECHANICAL CONDITION

THIS MOTORCYCLE IS BEING SOLD AS A NON-RUNNING PROJECT IN AS-IS CONDITION.

The engine turns over freely using the original kickstarter and appears to have good compression. The transmission shifts in and out of gear.

The factory-style carburetor assembly, airbox, and original four-cylinder exhaust configuration remain present.

However, because this motorcycle was acquired from an estate, we do not know the complete mechanical history or how far the previous owner progressed with its restoration.

The motorcycle has not been fully serviced, recommissioned, or road-tested by our shop.

Before attempting to operate the motorcycle, we recommend a complete mechanical inspection and appropriate servicing, including, but not limited to:

This is an approximately 52-year-old investment quality antique vintage motorcycle that will require mechanical work before being returned to service.

The good news? It is a highly complete, cosmetically attractive project with several major restoration expenses already addressed.

WHY THE 1975 HONDA CB750 FOUR IS SO COLLECTIBLE

When Honda introduced the CB750 Four in 1969, it revolutionized the motorcycle industry.

The CB750 helped establish the modern superbike category by delivering a combination of performance, reliability, refinement, and advanced engineering that changed the industry forever.

Its smooth 736cc inline four-cylinder engine, electric starting, front disc brake, and overhead-cam design were remarkable for a production motorcycle of its era.

By 1975, the CB750 K5 represented a refined version of Honda's legendary original superbike.

Factory specifications include:

These motorcycles have developed a tremendous following among collectors and enthusiasts worldwide.

The CB750 Four is not simply an antique motorcycle. It is one of the most historically important production motorcycles ever built.

COLLECTOR VALUE & RESTORATION POTENTIAL

We have sold numerous early Honda CB750 Fours over the years, including examples from the 1969–1976 model range.

Our experience has shown that properly restored examples can command substantial prices.

We have previously sold 1975 CB750s in the 12,000–15,000 range, depending on restoration quality, originality, and overall condition.

We believe this particular motorcycle has excellent restoration potential and could be worth well north of $10,000 if properly restored to a high standard, depending on market conditions.

With its beautifully refinished tank and side covers, well-preserved factory seat, intact original four-pipe exhaust, and clean title, this CB750 offers an excellent foundation for someone willing to complete the mechanical work.

Whether you're looking for a winter restoration project, a classic motorcycle to add to your collection, or a legendary Honda to bring back to life and ride, this one deserves serious consideration.

PART OF A MAJOR VINTAGE HONDA ESTATE COLLECTION

This motorcycle came from a collection of 23 vintage motorcycles acquired from Mike's estate.

Among the Hondas in this group are a CB550 Four, CB500T, two CB350 twins, MR250, and a vintage Honda 50.

At Kaplan Cycles, we currently have approximately 240 motorcycles in inventory, with additional collections arriving from Ohio, Texas, and Virginia.

As much as we would love to restore every motorcycle, the sheer volume of incoming inventory makes that impossible.

We have therefore decided to offer selected motorcycles from these collections directly to the public in their current condition.

THIS IS YOUR OPPORTUNITY TO PURCHASE A HIGHLY COLLECTIBLE HONDA CB750 PROJECT BEFORE WE INVEST THE TIME AND MONEY INTO RESTORING IT!
