Piaggio Hexagon

                          Piaggio Hexagon 



Model History 

The first models were the Hexagon EX 150 and two years later the Hexagon EX 125, which were replaced by the modified models LX 125 and LXT 180. Later came with the models LX4 and GT for the first time single-cylinder four-stroke engines with 125 cc and 250 cc used, the 250 cc engine comes from Honda . From 2000, the Hexagon was delivered with 125 and 180 cc Leader engines . The renaming in Super Hexagon , however, was purely cosmetic.

Technology 

For the drive unit a power take-off rocker was used, ie the sprung rear swing arm contains the entire drive with motor, variator , clutch and final gear. As engines water-cooled single-cylinder two-stroke and four-stroke engines with displacements between 125 cm³ and 250 cm³ were used. Only the type LX4 had an air-cooled 4-stroke engine.
The continuously variable belt transmission transmits the power via a centrifugal clutch to the rear wheel. Since the CVT transmission does not need to be shifted, and the centrifugal clutch operates automatically, the scooter was very easy and comfortable to move.
The chassis of all 2-stroke had the rear of the drive train swing arm with a single shock absorber, which, however, like all propulsion rocker, had the disadvantage of a relatively large unsprung mass and therefore was not particularly comfortable. The front wheel was suspended as with the Vespa with a pulled rocker and a single shock absorber. The models had until 1998 10-inch wheels. For stability and comfort, the models were from 1998, a chassis with 11-inch wheels, the last models of the Hexagon were delivered with a telescopic fork front and 12-inch wheels. On all four-stroke engines, an auxiliary swingarm was added to the rear wheel on the right, and a double rear shock absorber was installed instead of the single shock absorber.
The Hexagon had a front hydraulic disc brake, in the models before 1998 with a fixed 2-piston caliper and a disc diameter of 175 mm, after 1998 a floating 2-piston caliper with a disc diameter of 200 mm. The Bowden-operated rear brake until 1998 was a drum brake with 110 mm drum diameter, after 1998 with 140 mm drum diameter. The 4-stroke GTX models also had a hydraulic disc brake at the rear.
The electrical system of the 2-stroke engine consists of a battery-powered independent capacitor ignition system (CDI = Capacitor Discharge Ignition) and a generator system with regulator that charges a lead-acid battery while the engine is running and supplies all other consumers (except the ignition). The models until 1998 had a single headlamp with H4 light, the models from 1998 a double headlamp with H7 / H1 light, which brought a much better light output. In the 4-stroke the CDI is changed, and has an immobilizer.
