The '''Honda CB750''' is an [[air-cooled]], [[Transverse engine|transverse]], [[Straight-four engine|in-line four-cylinder]] engine [[motorcycle]] made by [[Honda]] over several generations for year models 1969–2003 as well as 2007 with an upright or [[Types of motorcycles#Standard|standard]] riding posture. It is often called the original [[Universal Japanese Motorcycle]] (UJM).<ref name=Walker2006/><ref name=Frank2003>{{Citation |title= Honda Motorcycles |first= Aaron |last= Frank |publisher = MotorBooks/MBI Publishing Company |year= 2003 |isbn= 0-7603-1077-7 |url= https://books.google.com/books?id=CSxTaoGagKoC&pg=PA92 |access-date= 20 February 2010 |page=92 }}</ref>

Though other manufacturers had marketed the transverse, [[overhead camshaft]], inline four-cylinder engine configuration and the layout had been used in racing engines prior to World War II, Honda popularized the configuration with the CB750, and the layout subsequently became the dominant [[sport bike]] engine layout.

The CB750 was the first motorcycle to be called a "superbike".<ref name="Landon Hall"/><ref name=TAM/>

==History==
Honda of Japan introduced the CB750 motorcycle to the US and European markets in 1969 after experiencing success with its smaller motorcycles.  In the late 1960s Honda motorcycles were, overall, the world's biggest sellers. There were the C100 Cub step-through—the best-selling motorcycle of all time—the C71, C72, C77 and CA77/8 Dreams; and the CB72/77 Super Hawks/Sports. A taste of what was ahead came with the introduction of the revolutionary [[Honda CB450|CB450]] DOHC twin-cylinder machine in 1966. Profits from these production bikes financed the successful racing machines of the 1960s, and lessons learned from racing were applied to the CB750. The CB750 was targeted directly at the US market after Honda officials, including founder [[Soichiro Honda]], repeatedly met US dealers and understood the opportunity for a larger bike.

===Early racing===
In 1967 American Honda's service manager [[Bob Hansen (motorcycling)|Bob Hansen]]<ref>Girdler, Alan. [http://www.cycleworld.com/2013/03/07/remembering-the-life-of-bob-hansen-1919-2013/ Bob Hansen, 1919–2013 A long and rewarding life.] ''[[Cycle World]]''</ref><ref>{{mhof|66|Bob Hansen}}</ref> flew to Japan and discussed with Soichiro Honda the possibility of using Grand Prix technology in bikes prepared for American motorcycle events. American racing's governing body, the [[American Motorcyclist Association|AMA]], had rules that allowed racing by production machines only, and restricted overhead-valve engines to 500&nbsp;cc whilst allowing the side-valve Harley Davidsons to compete with 750&nbsp;cc engines.<ref name="M online">[http://www.motorcyclistonline.com/blogs/dick-manns-1970-daytona-200-victory-mann-machine Mann and machine, Motorcyclist online] Retrieved 13 June 2015</ref> Honda knew that what won on the race track today, sold in the show rooms tomorrow, and a large engine capacity road machine would have to be built to compete with the Harley Davidson and Triumph twin-cylinder machines.

Hansen told Soichiro Honda that he should build a 'King of Motorcycles'{{Failed verification|date=July 2019}} and the CB750 appeared at the Tokyo Show in November 1968 and was publicly launched in UK at the [[Brighton]], England motorcycle show held at the [[Hilton Brighton Metropole|Metropole Hotel exhibition centre]] during April 1969,<ref name="MC Sport"/><ref name="Mechanics"/> with an earlier press-launch at Honda's London headquarters,<ref name="MC Sport">''Motorcycle Sport'', UK monthly magazine, April 1969, pp. Cover, 121, 132–133.

The AMA Competition Committee recognised the need for more variation of racing motorcycle and changed the rules from 1970, by standardizing a full 750&nbsp;cc displacement for all engines regardless of valve location or number of cylinders, enabling [[BSA Rocket 3/Triumph Trident|Triumph and BSA]] to field their 750&nbsp;cc triples instead of the 500&nbsp;cc [[Triumph Tiger Daytona|Triumph Daytona]] twins.<ref name="M online"/>

The Honda factory responded by producing four works-racer CR750s, a racing version of the production CB750, ridden by UK-based [[Ralph Bryans]], [[Tommy Robb (motorcyclist)|Tommy Robb]] and [[Bill Smith (motorcyclist)|Bill Smith]] under the supervision of Mr Nakamura, and a fourth machine under Hansen ridden by [[Dick Mann]]. The three Japanese-prepared machines all failed during the race with Mann just holding on to win by a few seconds with a failing engine.<ref name="M online"/>

==Production and reception==

Under development for a year,<ref name=CW1969>{{citation |magazine=[[Cycle World]] |date= January 1969|title= Honda's Fabulous 750 Four; Honda Launches the Ultimate Weapon in One-Upmanship — a Magnificent, Musclebound, Racer for the Road |pages=36–39 |issn=0011-4286 }}</ref> the CB750 had a transverse, straight-four engine with a single [[overhead camshaft]] (SOHC) and a front disc brake, neither of which was previously available on a mainstream, affordable, production motorcycle. Having a four-cylinder engine and disc brake, along with the introductory price of US${{Formatnum: 1495}}<ref name=Cycle1969/> (US${{Formatnum: {{inflation|US|1495|1969}} }} in current money), gave the CB750 a considerable sporting performance advantage over its competition, particularly its British rivals.

''[[Cycle (magazine)|Cycle]]'' magazine called the CB750, "the most sophisticated production bike ever", on the bike's introduction.<ref name=Cycle1969>{{Citation |magazine=[[Cycle (magazine)|Cycle]] |date= August 1969 |title=Cycle Road Test: Honda 750cc Four |pages=33–39, 78–81 }}</ref> ''[[Cycle World]]'' called it a masterpiece, highlighting Honda's painstaking durability testing, the bike's {{convert|120|mph|abbr=on}} top speed, the fade-free braking, the comfortable ride, and excellent instrumentation.<ref name=CW1969/>

The CB750 was the first modern four-cylinder machine from a mainstream manufacturer,<ref name="MotoPedia">{{Citation |author=Wilson, H. |title=The Encyclopedia of the Motorcycle |pages=88–89 |publisher=Dorling Kindersley Limited |year=1995 |isbn=0-7513-0206-6}}</ref> and the term [[superbike]] was coined to describe it.<ref name=Walker2006 /><ref name=AMA/> Adding to the bike's value were its [[electric starter]], [[kill switch]], dual mirrors, flashing turn signals, easily maintained valves, and overall smoothness and low vibration both under way and at a standstill. Much-later models from 1991 included maintenance-free hydraulic valves.

Unable to accurately gauge demand for the new bike, Honda limited its initial investment in the production dies for the CB750 by using a technique called [[permanent mold casting]] (often erroneously referred to as sandcasting) rather than diecasting for the engines<ref name=HondaHistory>{{Citation | title=Employing an Idle Facility to Produce a Large Motorcycle | url=http://world.honda.com/history/challenge/1969cb750four/page04.html |access-date=25 August 2014 }}</ref> – unsure of the bike's reception. The bike remained in the Honda line up for ten years, with a production total over 400,000.<ref name=Alexander>{{Citation |title= Japan's Motorcycle Wars: An Industry History |first= Jeffrey W. |last= Alexander |publisher= [[UBC Press]] |year= 2009 |isbn= 978-0-7748-1454-6 |url= https://books.google.com/books?id=Q473NKddjnAC&pg=PA206 |page= 206 |access-date=5 April 2011 }}</ref>

In 1976, Honda introduced the CB750A to the United States, with the ''A'' suffix designating "Automatic", for its automatic transmission. Although the two-speed transmission includes a torque converter typical of an automatic transmission, the transmission does not automatically change gears for the rider. Each gear is selected by a foot-controlled hydraulic valve/selector (similar in operation to a manual transmission motorcycle).<ref name=Bacon1996>{{Citation |title= Honda: The Early Classic Motorcycles : All the Singles, Twins and Fours, Including Production Racers and Gold Wing-1947 to 1977 |first= Roy |last= Bacon |publisher= Niton Publishing |year= 1996 |isbn= 1-85579-028-9 |pages=110, 112, 185, 192}}</ref><ref name=Ker2007>{{Citation |last=Ker |first=Rod |title=Classic Japanese Motorcycle Guide |year=2007 |isbn=978-1-84425-335-7 |publisher=[[Haynes Manual|Haynes Publishing]] |location=[[Sparkford|Sparkford, UK]] |page=81}}</ref> The foot selector controls the application of high pressure oil to a single clutch pack (one clutch for each gear), causing the selected clutch (and gear) to engage. The selected gear remains selected until changed by the rider, or the kickstand is lowered (which shifts the transmission to neutral).<ref name=CWSeptember1976/>

The CB750A was sold in the North American and Japanese markets only.<ref name=Ker2007/> The name [[Hondamatic]] was shared with Honda cars of the 1970s, but the motorcycle transmission was not fully automatic. The design of the transmission is similar in concept to the transmission in Honda's [[Honda N360|N360AT]],<ref name=CWSeptember1976/><ref>The Hondamatic Transmission, The Innovative Automatic Transmission: A Breakthrough in Original Thinking, 1968</ref> a [[kei car]] sold in Japan from 1967 to 1972.

The CB750A uses the same engine as the CB750, but detuned with lower 7.7:1 compression and smaller carburetors producing a lower output, {{convert|47.0|hp|abbr=on|order=flip}}. The same oil is used for the engine and transmission, and the engine was changed to a [[wet sump]] instead of [[dry sump]] type. A lockout safety device prevents the transmission from moving out of neutral if the side stand is down. There is no tachometer but the instruments include a fuel gauge and gear indicator. For 1977 the gearing was revised, and the exhaust changed to a four-into-two with a silencer on either side. Due to slow sales the model was discontinued in 1978,<ref name=Bacon1996/> though Honda did later introduce smaller Hondamatic motorcycles (namely the [[Honda CB400T#CB400A Hawk Hondamatic|CB400A]], [[Honda CM400|CM400A]],<ref name="hondacbcmshop">{{cite book|title=Honda Shop Manual CB/CM400's|publisher=Honda Motor Co.

In 2007 Honda Japan announced the sale of a new CB750 very similar to the models sold in the 1970s. Announced as the CB750 Special Edition that was in the silver colors of the CB750 AMA racer of the 1970s and the CB750, it was offered in three color schemes reminiscent of CB750s previously sold. {{As of|2007|08}}, these bikes were intended only for release in Japan.<ref name="cb750se">{{Cite web|url=http://www.honda.co.jp/motor-lineup/cb750/photo/index.html|archive-url=https://web.archive.org/web/20090531070030/http://www.honda.co.jp/motor-lineup/cb750/photo/index.html|url-status=dead|title=Honda Japan website|archive-date=31 May 2009}}</ref>
