Velorex sidecars Demand for motorcycle and sidecar combinations in the Soviet Union brought a requirement for Jawa to build a motorcycle capable of pulling a sidecar and Velorex to build a sidecar for it. In response, Jawa built their 354 motorcycle with enough strength and power for sidecar use, and Velorex built the Type 560 sidecar. In 1974, Jawa built the 350cc Type 634 motorcycle, which was designed even more specifically for use in a sidecar combination in the Soviet Union. The Jawa Type 634 produced 28 BHP @ 5,252 RPM and an impressive 38 Foot / Pounds of Torque @ 3,800 RPM, equal to the original 750cc Triumph Boneville. The electrics were powered by a 6 Volt 75 Watt dynamo as opposed to the Jawa Type 354's 6 Volt 45 Watt dynamo system. In response, Velorex created the Type 562 sidecar, which was stronger than the Type 560, but was also simpler to assemble, thereby improving the production rate which had been a problem in manufacturing the Type 560. Velorex manufactured approximately 290,000 Type 562 sidecars from 1974 to the late 1990s. In 1986 Jawa replaced the Type 634 motorcycle with the more powerful 350cc Type 638 motorcycle, which originally produced 34 BHP @ 6,500 RPM and 30 Foot / Pounds of torque @ 3,800 RPM, which was also available with the Velorex 562 sidecar attached. The Type 638 was detuned, from 1988 onwards, to 25 BHP @ 5,252 RPM for European Union emissions considerations. For the Dutch market it was detuned further to 23 BHP @ 5,252 RPM to cater
