1969 HONDA SANDCAST CB750 $130K on eBay

Woah!

THE CB750 SANDCAST PROTOTYPE!



THE HISTORY

Many know the story of the first Superbike: when Mr. Soichiro Honda started a 4 cylinder revolution back in 1969, with his “King of Motorcycles”. It was the bike that changed motorcycling.

That CB750 featured a transverse in-line 4 cylinder 736cc engine, that produced 67 horsepower, and a top speed of 125 miles per hour. It also came with an electric starter and a disc brake!

The first 7000 or so CB750s that came off the factory assembly line in Japan back in 1969, had engine cases that were cast in sand.

Those scarce early sandcast CB750s now regularly command high prices amongst collectors around the world.



THE PROTOTYPE

What only some sandcast aficionados know, is that before the now rare sandcast CB750s were produced in 1969, Honda determined that they first needed to build a set of “preproduction” prototypes to market their “The King of Motorcycles” to the American public. So in 1968 they decided to build samples of this new ground breaking CB750 to unveil at their annual Las Vegas Motorcycle Dealer Show, as well as to provide eye-candy for the various trade magazines, and for promotional photography, advertisements, etc.

What Honda sent over to the U.S. were 4 preproduction bikes:

• A Candy Red prototype


• A Candy Gold prototype


• A Candy Dark Green Metallic prototype


• And the feature of this special auction, the Candy Blue/Green prototype


These 4 special preproduction bikes were literally hand-built by Honda technicians, using many hundreds of unique one-off preproduction parts, to promote their new flagship line of motorcycles.

The unique character of these rare preproduction bikes is readily noticeable when examining each and every component part. For example:

• One-off sandcast engine covers, featuring an external “double step” on the Alternator cover


• A wedge shaped transmission cover, fitting UNDER the Alternator cover


• Very unusual clutch and valve covers (both appearing nothing like the street bike counterparts, and are very rough cast)


• A one of a kind Billet Crankshaft (meaning it was turned and machined from one solid chunk of special steel bar)


• Chrome fenders showing (under the chrome plating) engineer’s scribe marks to mark off where holes should be drilled


• Hand hammered/welded exhaust pipes


• One-off special cast by Keihin 26mm carb assemblies


• Handmade white plastic parts throughout the motorcycle (while street version bikes have all black pieces)


• Longer rear fender having brazed on turn signal stems


• A 43 tooth rear sprocket (vs. 45 for production)


• No handlebar kill switch


• No provision for a tool tray under the seat


• Sandcast “hollow” fuel tank emblems


• Cast gas cap and latch


• And literally hundreds more of distinctly different parts than standard, many of which are illustrated in the enclosed photos (Note: ALL vintage American Honda photos and flyers seen here are of the exact bike in this auction)




What ever happened to those rare first four hand built bikes?

The Red bike was taken to the crushers in Iowa back in the early 1990s (I know, as we got there literally days too late, coming away with only a small handful of parts from it).

The Gold bike made its way to Europe, only to be completely disassembled by its owner (who has no intention of selling) and it has remained in that state for the last 25 years or so.

The Dark Green bike has never been heard from, thus leaving this (Blue/Green) bike left of the four.

The Blue/Green prototype motorcycle featured in this auction just happens to also be the (only) one American Honda used for all of its initial promotional brochures, flyers, and sales literature. Example photos of these early promotional items can be seen here, and most easily identified by the bike's very unusual front brake caliper.

I located this Prototype motorcycle through a friend some years ago, and quickly decided that it in fact did not need “restoration”, but rather just needed to be cleaned up and put back together, as the original paint and overall condition was quite nice. It is a very strong running motorcycle.

Please view the attached photographs to see more about this extraordinary motorcycle. Note: Where you see similar components shown in the same photo, it is simply a comparison between the part from this prototype, vs. a stock CB750 part.



ABOUT THE SELLER:

Vic World has a passion for Honda CB750s; that revolutionary motorcycle that turned the industry on it’s ear back in the summer of ’69. His particular area of expertise, is in the restoration of the rare early sandcast bikes, that were the first to roll off Honda’s Hamamatsu line back in early ’69. His thirty plus years of relentless focus on this motorcycle, has earned him the moniker of “Mr. CB750.” Vic is widely acknowledged as the premier restorer of these rare bikes and he has been written about in many trade publications, including a feature article by Mitch Boehm in Motorcyclist Retro. His restorations are highly sought after and have been purchased by museums, including a featured exhibition in Honda’s own Collection Hall Museum in Japan. American Honda owns a Vic World restoration, as does the Barber Museum in Birmingham, Alabama. Mr. World resides in San Francisco, where he operates World Motorcycles, a shop that specializes in the restoration of sandcast CB750s.
