for Holland's unique emissions requirements at that time. In 1990 Jawa reintroduced the Type 634 engine, now featuring a 12 Volt 228 Watt Magneton alternator, in the Type 638 motorcycle chassis as the Type 632. This proved to be a better sidecar machine than the now detuned Type 638 motorcycle. In 1990 Velorex produced the Type 710 sidecar and this was marketed with the Type 632 motorcycle attached. The Type 638 with a disc front brake and Velorex Type 710 sidecar attached was also marketed alongside the Type 632 combination as the Type 639 from 1990. Jawa motorcycles built for sidecar use, as opposed to solo motorcycle use, feature smaller 15 or 16 tooth gearbox sprockets (18 teeth on solo bikes), an attachment on the rear brake cable pivot arm for the sidecar's own brake cable to attach, a left footrest with an attachment for the sidecar brake cable to fit into and modified wiring loom at the rear of the bike with electrical power coupling for the sidecar's lighting and accessories. An adjustable friction type steering damper was fitted under the headstock on some machines, though this later proved to be unnecessary due to the good handling characteristics of the unit as a whole. This feature was occasionally fitted to the Type 634, Type 638, Type 632, Type 639 and Type 640 machines from 1974 to date. The Velorex Type 710 featured a more streamlined shape, resembling a jet fighter cockpit with a large forward opening perspex windshield, plus an interior space with plenty of leg room. Stowage behind the now full height backrested seat was 3 times the capacity of the Type 562 sidecar. Because of this the Type 710 was and still is regarded as the best sidecar Velorex ever produced. Both the Type 562 and Type 710 sidecars share the same chassis, with only the bodywork being different. Both feature either a 16 Inch or 18 Inch wheel with a 160mm. diameter single leading shoe drum brake, which is linked, when fitted to a Jawa motorcycle, to the rear brake mechanism to provide balanced braking. Both the Velorex Type 562 and Type 710 sidecars were marketed separately worldwide with fitting kits for various foreign motorcycle types including Harley Davidson, Honda, Triumph, etc. Currently Jawa still sells the 350cc Type 640 combination with the Velorex Type 562 sidecar in Europe and the United Kingdom, this currently being
