The '''Honda CB750K''' was a 736[[cc]], [[four stroke]], [[four cylinder]], [[street motorcycle]] manufactured by [[Honda]] from 1968 through 1982.  The model is included in the [[American Motorcyclist Association|AMA]] Hall of Fame Classic Bikes,<ref>{{Citation |url=http://www.motorcyclemuseum.org/classics/bike.asp?id=91 |title=1969 Honda CB750; The Year of the Super-bike |author=Motorcycle Hall of Fame |publisher=[[American Motorcyclist Association]]}}</ref><ref name=AMA>{{Citation |title=The Dawn of the Superbike: Honda's Remarkable CB750 |url=http://www.motorcyclemuseum.org/exhibits/superbikes/CB750/CB750.asp |accessdate=2010-02-20 |work=[[Motorcycle Hall of Fame|AMA Motorcycle Hall of Fame]] |publisher=[[American Motorcyclist Association]] }}</ref> the Discovery Channel's "Greatest Motorbikes Ever"<ref name=Discovery>{{cite web | url= http://www.discoverychannel.co.uk/greatest_ever/motorbikes/index.shtml | work= Discovery Channel| title= Greatest Motorbikes Ever}}</ref>

==History==
In June of 1968, [[Honda]] dropped the gauntlet that would forever change the world of motorcycling. The CB750 "Four" offered a combination of features never before seen on a single [[motorcycle]]. No longer would Honda be known as [[scooter]] company.  



At the heart of the CB750K was an inline four-cylinder engine with a single overhead cam, four carburetors, four-into-four exhaust pipes. It produced 67 horsepower at 8000 rpm which was 15-percent more power than [[BSA]]'s new [[BSA Rocket 3|750 cc Rocket 3]] even though they weighed about the same (just under 227 kg (500 pounds)). The Honda, obviously, was much faster.

It was not just the four-cylinder engine that caused such a stir; though most contemporary competitors had twin cylinders, fours had been offered by several manufacturers in the past. Rather, it was the fact that the four-cylinder power and smoothness was joined by a five-speed transmission, electric starter, a front disc brake, and a nearly bullet proof design&mdash;the first ever on a street bike&mdash;all at a reasonable price.

The single cam version was produced without much refinement until 1978 when it was replaced with a long awaited, more modern, double cam model.

Honda also sold a race kit to convert the CB750 into a [[Honda CR750]] race ready bike.

In 1975 Honda introduced the [[Honda_CB750F|"F" or "SuperSport"]] model which had a rear disc brake and a 4 into 1 header as well as some other cafe inspired additions. The same year they also introduced the [[Honda CB750A|"A" or "HondaMatic"]] model which was a clutchless 2-speed model with a wet sump lubrication system. 

Honda also produced smaller fours in 350,400,[[Honda CB500K|500]],[[Honda CB550K|550]] and [[Honda CB650|650]] displacements.

Earlier CB750s were produced with sand-cast cases that had a rough finish, later models had smoother castings. Those early sand-cast models have become the most valuable to collectors.

By 1970, [[Dick Mann]] piloted a race-prepped CB750 into the winner's circle at the [[Daytona 200]] and the world of spurring aftermarket upgrades to the CB750. The CB750 is also credited with casting the mold for what would later be called the "[[Universal Japanese motorycle‎]]", a breed of machines that would bring the [[Motorcycle]] manufacturers of England to their collective knees.

Under development for one year, when finally introduced to the market, The CB750 offered two unprecedented features: its disc brake and its inline four cylinder engine -- neither of which were previously available on mainstream, affordable, production bikes. These two features, along with the bike's introductory price of $1495.00 (US), gave the CB750 considerable advantage over its competition, particularly its British rivals.

''Cycle Magazine'' called the CB750 "the most sophisticated production bike ever" upon its introduction. ''Cycle World'' called the motorcycle a masterpiece, highlighting Honda's painstaking durability testing, the bike's 120mph top speed, the fade-free performance of the braking, the comfortable ride, and excellent instrumentation .

As the first modern four cylinder machine from a mainstream manufacturer, the term Superbike was coined to describe the CB750. The bike offered other important features, both great and small that added to its compelling value: electric starter, kill switch, dual mirrors, flashing turn signals, screw on oil filter, maintenance free valves and overall smoothness and freedom from vibration both underway and at a standstill. On the other hand, the bike was difficult to get on its center stand and tended to throw chain oil on its muffler.

Unable to accurately gauge demand for the new bike, Honda limited its initial investment in the production dies for the CB750 by originally using a technique called permanent mold casting (often erroneously referred to as sand casting) rather than die-casting for the engines -- unsure of the bike's reception. The bike remained in the Honda lineup for ten years, sales totaling over 400,000 copies in its life span

The CB750 is sometimes referred to as a Universal Japanese Motorcycle or UJM, although certainly the bike has earned notoriety of its own. The Discovery Channel ranked the Honda CB750 among the top ten greatest motorbikes of all time, giving the CB750 third place.

In 2007, Honda Japan announced the sale of a new CB 750 very similar to the models sold in the 1970s. Announced were the CB 750 Special Edition (list price 798,000 yen) which is in the silver colors of the CB 750 AMA racer of the 1970s, and the CB 750 (list price 730,000 yen) in 3 color schemes reminiscent of CB 750s sold previously. As of August 2007, these bikes have only been announced for the Japan domestic market.
