In 1982 the more expensive JS8 model appeared, mostly the same as the JS4 but equipped with a 125 cc BCB engine. The more capable JS8 jas 7.5 hp (5.5 kW) and required an A4 permit (tricycle/quadricycle), unlike the JS4 (and later JS6) which required no permit at all as they had less than 5 hp (3.7 kW) and a top speed under 45 km/h (28 mph).
