Engine : 4-stroke, single-cylinder, air-cooled - bore x stroke 76 x 75 mm - displacement 340.2 cc - compression ratio 9:1 - overhead camshaft and two valves in the cylinder head - wet sump with pump - Dell'Orto PHF 30 AS carburettor - multi-disc wet clutch - 5-speed gearbox - primary drive by gears - secondary drive by chain. This model features the "wide" crankcase which had a larger oil capacity and allowed for the inclusion of a fifth gear.

Electrical system: The lighting is battery-powered, and the battery is recharged by a MOTOPLAT alternator via a rectifier. The YUASA battery (12V, 12Ah), which is charged by the alternator and rectifier, powers the parking lights (city lights and taillights) and turn signals when the engine is off.

Performance : 22 hp at 6000 rpm - maximum speed 145 km/h in normal position - fuel consumption 5 litres/100 km.
Colour scheme: Metallic red paint for the tank and side covers. Chrome for the headlight and mudguards, and black for the frame, swingarm, and chain guard.
Clarification note: There was an early 300cc version that only included a front disc brake and did not have alloy wheels. Later, in 1980, a second version was developed that included disc brakes on both wheels, alloy wheels, and a matte black engine. It was orange in colour (although the last motorcycles of the first series could also be painted in this colour). The electrical system was changed to 12 volts instead of the 6 volts used previously in motorcycles. In these later versions, some motorcycles were fitted with Telesco front forks and shock absorbers, or Betor, or combinations of both brands, or Mototrans forks, depending on the stock available at the time.
