The Ducati 860 GT Ducati 860 GTS and motorcycles were the Italian manufacturer Ducati.

History

, Designed by Giorgio Giugiaro successor to the Ducati 750 GT was presented at the Milan Show in the fall of 1973 the first time. In keeping with the angular design of the tank and the side cover of the motor housing were redesigned - the so-called round engine was replaced.

As in the U.S. since 1974, the links circuit was prescribed, Ducati produced from 1975 equipped the 860 GT accordingly.

Technology

Motor

The camshaft drive was carried out by two vertical shafts, the drive has been simplified compared to the forerunner 750 GT. The valve control has been conventionally carried out on a camshaft per cylinder head, rocker arms and coil springs; as well as the valve lash setting on adjustment screws with lock nuts - not with shims as the 750 GT.

The bypass oil filter, the oil purified in the rear cylinder.

The maintenance-free, electronically controlled magneto ignition ( contactless thyristor ignition system ) came from Ducati Elettronica.

Landing gear

A Ceriani fork led the front wheel, the rear suspension Marzocchi shocks were installed The frame was substantially different from that of the Super Sport models. The chain tension was not thus set as the SS versions that the rear axle has been moved to the swingarm. The rear axle was instead clamped immovably in the swingarm, the swingarm axle was mounted in eccentric bushings in the frame, the sockets were held in a clamp. The chain tension was regulated by switching the whole link was moved by rotating the eccentric bushings. This construction ensures that the rear wheel is always right track in the rocker, because a different move the tensioner is impossible on the side of the swingarm. The necessary special tool was available to all machines in the tool kit.

Versions

Just one year after the introduction of the GT, GTS was introduced with a modified tank for better knee grip, flatter seat and numerous detail changes.

The ignition lock was located between the speedometer and tachometer; the choking wandered beside the speedometer.
