Van Veen or Van Veen Kreid is a former motorcycle manufacturer. It was founded in Amsterdam by Henk van Veen, the Dutch importer of Kreidler motorcycles. [1]
Van Veen completed its first prototype in 1974 using a 1000 cc Comotor 624 twin-rotor Wankel engine, and in November 1974 it was exhibited at the Cologne motorcycle show with front and rear cast wheels and triple Brembo disc brakes. [3]
Limited production of the OCR 1000 model began in 1978 and ceased in 1981, after poor press reviews and complications with Comotor engine production. [1] As well as problems with the Comotor engine, weight (700 lbs/320 kg) and price ($US15,000) also contributed to lack of sales. [4] 38 examples were built. [4]
By 2011, the leftover OCR 1000 parts had been purchased by Andries Wielinga, who built 10 complete motorcycles for sale. [1]
Felix Heinrich Wankel was a German mechanical engineer and inventor after whom the Wankel engine was named.
The Wankel engine is a type of internal combustion engine using an eccentric rotary design to convert pressure into rotating motion. It was invented by German engineer Felix Wankel, and designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor, which creates the turning motion, is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor rotates inside an oval-like epitrochoidal housing, around a central output shaft. The rotor spins in a hula-hoop fashion around the central output shaft, spinning the shaft via toothed gearing.

Comotor SA was a joint venture between NSU and Citroën, created in Luxembourg in April 1967. Its goal was to produce Wankel engines.
A motorcycle engine is an engine that powers a motorcycle. Motorcycle engines are typically two-stroke or four-stroke internal combustion engines, but other engine types, such as Wankels and electric motors, have been used.

The Suzuki RE5 is a motorcycle with a liquid-cooled single-rotor Wankel engine, manufactured by Suzuki from 1974 to 1976. Apart from its unusual engine, the RE5 is mostly a conventional roadster, albeit with some peculiar styling details thanks to Italian industrial designer Giorgetto Giugiaro.
Norton Villiers Triumph (NVT) was a British motorcycle manufacturer, formed by the British government to continue the UK motorcycling industry, until the company's ultimate demise.

The Norton Classic is a rotary-engined motorcycle built in 1987 by Norton as a special edition of just 100 machines.
The General Motors Rotary Combustion Engine (GMRCE) is an internal combustion Wankel engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. In November 1970, GM paid $50 million, ($348,886,033 in 2021 dollars ), for initial licenses to produce their version of the Wankel rotary engine, and GM President Ed Cole initially projected its release in three years. Chevrolet, with impetus from Pete Estes and John DeLorean, as well as Ed Cole worked on the Wankel. Bob Templin was the chief executive in charge of rotary-engine research at the GM Tech Center in Warren, Michigan, but Ed Cole would leave his office in Detroit twice a week for the trip to Warren, taking charge of the program. The engine was initially targeted for an October 1973 introduction as a 1974 Chevrolet Vega option. Its mediocre fuel economy and the ill-timed Arab oil embargo were contributing factors to end the GM rotary program.
The MidWest AE series are lightweight, liquid-cooled, single- and twin-rotor Wankel engines, with dual ignition, designed for light aircraft. They were produced by Mid-West Engines Ltd. at Staverton Airport, Gloucestershire, UK.
Motorcyclewheels are made to cope with radial and axial forces. They also provide a way of mounting other critical components such as the brakes, final drive and suspension. Wheels, and anything directly connected to them, are considered to be unsprung mass. Traditionally motorcycles used wire-spoked wheels with inner tubes and pneumatic tyres. Although cast wheels were first used on a motorcycle in 1927, it would not be until the 1970s that mainstream manufacturers would start to introduce cast wheels on their roadgoing motorcycles. Spoked wheels are usually made using steel spokes with steel or aluminium rims. Cast wheels are predominantly made from an aluminium-alloy, but can also be made from more-exotic materials, such as magnesium content alloy or carbon fibre.
The Hercules W-2000 is a motorcycle which was made by Hercules in Germany. It was the first production motorcycle with a Wankel engine.
