The Honda CM400 is a street bike produced by the Honda Motor Company from 1979 to 1982, part of a series of motorcycles with the prefix 'CM' using various engine capacities. It was a precursor to the Honda Rebel series of motorcycles. It was equipped with electric start and electronic ignition. Models included the CM400A (Automatic or "Hondamatic"), CM400C (Custom), CM400E (Economy) and CM400T (Touring). The CM400C was produced only in 1981, making it one of the rarer models.

The Honda CM series all generally resembled the older-style flat-seat bikes from the 1960s and 1970s, with the exception of a slightly raised passenger area seat and small plastic fairings for the battery and electrical. These are "standard" style motorcycles but do have some elements of the cruiser (stepped seat, increased fork angle, extra chrome).

The CM400 series includes only a speedometer and three indicator lights (neutral, oil pressure, high beam) with a tachometer for the C and T models. The A (automatic) model has a gear indicator (N/1/2) in place of the tachometer and an additional indicator light for the parking brake, which is used since the A models have no manual clutch. The E (economy) model had wire wheels and drum brakes, while the others had Comstar wheels and a front disc/rear drum braking setup. While not particularly powerful, the CM400's handling makes it a suitable starter bike. Top speeds range from 65-80 mph. [ citation needed ]

Many engine components are common with the Honda CB400T models from the same year. The parallel twin engine has three valves per cylinder (two intake, one exhaust) and a five-speed manual or two-speed automatic transmission using a torque converter. In 1982, the CM engine was bored out to a 447 cc (27.3 cu in) engine and the series was renamed CM450

In the 1984 film Purple Rain , Prince, in the role of The Kid, rode a customized Honda CM400 and he is also seen with it on the cover to the soundtrack of the same name. [1]

<span class="mw-page-title-main">Honda Magna</span> Type of motorcycle

The Honda Magna is a cruiser motorcycle made from 1982 to 1988 and 1994 to 2003 and was the second Honda to use their new V4 engine shared with the VF750S Sabre and a few years later a related engine was fitted to the VF750F 'Intercepter', the later models used a retuned engine from the VFR750F with fins added to the outside of the engine. The engine technology and layout was a descendant of Honda's racing V4 machines, such as the NS750 and NR750. The introduction of this engine on the Magna and the Sabre in 1982, was a milestone in the evolution of motorcycles that would culminate in 1983 with the introduction of the Interceptor V4. The V45's performance is comparable to that of Valkyries and Honda's 1800 cc V-twin cruisers. However, its mix of performance, reliability, and refinement was overshadowed by the more powerful 1,098 cc "V65" Magna in 1983.

The Honda VFR400 series of motorcycles were a related series of 399 cc V4-engined motorcycles, which were essentially scaled-down versions of the larger VFR race models of the day. They were mainly developed for, and sold in, the Japanese domestic market, in part due to the tougher motorcycle drivers' license restrictions in Japan at the time for bike exceeding 400 cc.

<span class="mw-page-title-main">Honda CX series</span> Series of motorcycles

The Honda CX series motorcycles, including the GL500 and GL650 Silver Wing variants, were developed and released by Honda in the late 1970s, with production ending in most markets by the mid 1980s. The design included innovative features and technologies that were uncommon or unused at the time such as liquid cooling, electric-only starting, low-maintenance shaft drive, modular wheels, and dual CV-type carburetors that were tuned for reduced emissions. The electronic ignition system was separate from the rest of the electrical system, but the motorcycle could only be started via the start button.

One of the lines of Honda motorcycles is the CM Series and CMX Series of cruiser-style motorcycles. Some of the CM series engines existed in other motorcycles so we included them in this list. Some of the bikes using the CM/CMX engine or model line have been:

<span class="mw-page-title-main">Honda CD200 RoadMaster</span> Type of motorcycle

Honda introduced several 200cc motorcycles with similar engines but different body variations in the 1980s. The model introduced in South Africa and Pakistan was known as the CD200 RoadMaster. The engine had the same bore as the CD185 but low compression pistons (8.8:1) with a bore and stroke of 53.0 mm × 44.0 mm, compared to 9.0:1 Compression and 53.0 mm × 41.0 mm for the CD185. The result was less power, a higher fuel economy and a lower top speed. The alternator system was also different from the CD185. Apart from this the models were quite similar, using the same frames, suspension, wheels, tyres, and brakes.

<span class="mw-page-title-main">Honda CB175</span> Motorcycle

The Honda CB175 is a standard motorcycle made by Honda from 1969 to 1973. It had a 174 cc (10.6 cu in) four-stroke, straight-twin engine with a single overhead camshaft, two valves per cylinder, dual slide-valve carburetors, and dual exhausts. It was also equipped with a five-speed gearbox, 12-volt electrics, kick and electric start, front and rear drum brakes, turn signals, speedometer with trip meter, and tachometer, and was rated at 20 bhp (15 kW). An update in 1972, brought a more rounded gas tank and changes to the air box covers, along with some other minor trim changes. The CB175 was discontinued for 1974 and replaced by the CB200, a similar bike already in production. Although not technologically remarkable, Honda's small twins of the 1960s and 1970s were among their best sellers. Dual sport scrambler CL175, SL175 enduro style and touring CD175/CA175 versions were also produced.

The Honda Nighthawk 250 is a Honda standard motorcycle. It has a 234 cc (14.3 cu in) air-cooled parallel-twin engine. While the first Nighthawk (CB650) was manufactured in 1982, the first 250 Nighthawk was manufactured in 1991. It utilized the 1985–87 CMX250 Rebel engine with all new wiring and components and reshaped the Rebel cylinder head slightly as well as incorporating a larger carburetor and new valve cover. The motorcycle changed little over the years except for color. The Nighthawk 250 is essentially a light, maneuverable, inexpensive, economical, and easy to maintain bike. It is often used in Motorcycle Safety Foundation (MSF) motorcycle training. Its small size and low seat make it a popular model for riders of smaller stature. It has drum brakes and spoked wheels at front and rear, though later models in the Australian, U.K. and Japanese markets upgraded to front disc brakes and alloy wheels.

<span class="mw-page-title-main">Honda CM450A</span> Type of motorcycle

The Honda CM450A is a motorcycle made by Honda in 1982 and 1983. It was based on the CB400 and CM400 models (1978–1981), especially the CM400A Hondamatic (1980–1981). It had a 447 cc (27.3 cu in) SOHC parallel twin engine with two carburetors and a two-speed transmission with a torque converter. It was not a full automatic, however, because the rider had to manually shift between low and high. It is called automatic because there is no clutch required due to the torque converter, and shared the Hondamatic trade name with Honda cars that had true automatic transmissions. The chain-driven CM450A had a top speed of 90 miles per hour (140 km/h) and weighed 413 pounds (187 kg). Both models had a front disc brake and a rear drum brake. The suspension consisted of two shock absorbers at the rear and telescoping shock-absorbing front forks. The fuel tank had a 3.4 US gallons capacity. The exhaust was routed through a separate pipe and baffle on each side of the motorcycle, although both exhaust pipes shared a plenum under the motor. It had an electric start with a kick start as well.
