Ducati Pantah
Manufacturer	Ducati
Production	1980-1986
Successor	SuperSport
Class	Sportbike
Engine	90° V-twin

The Pantah was the first of the belt-driven camshaft Ducati motors, the first generation of the current Ducati V twins. Ducati Motor Holding SpA ( Borsa Italiana: DMH is an Italian Motorcycle manufacturer located in Bologna Italy. The Ducati SuperSport and SS are names applied to a series of Pantah based Air-cooled Four stroke two valve V-Twin motorcycles manufactured The Motorcycle Safety Foundation groups motorcycles into the following three separate classes street, off-road, and dual-sport. A motorcycle engine propels a Motorcycle. The engine typically sits immediately under the fuel tank in between and just forward of the rider's legs Configurations "True V-twin" vs V-2 There is some ambiguity regarding what defines a V-twin which arose from 180 degree "V" engines (see Ducati Motor Holding SpA ( Borsa Italiana: DMH is an Italian Motorcycle manufacturer located in Bologna Italy. First shown December 1979, it came on the market as the 1980 500SL and the last of the line 650SL was sold in 1986. Successful in racing as the 600 cc TT2 and later TT1 750 cc racer, it was a lighter, shorter wheelbase motorcycle, in a new trellis frame that was to become a trademark Ducati feature.

Pantah 500 cc

When the 1976 350 cc and 500 cc vertical twins were recognised as a marketing disaster, Fabio Taglioni went to work developing the Pantah. Fabio Taglioni ( September 10, 1920 &ndash July 18, 2001) was an Italian engineer

The Pantah 500 is where the current line of V twins began. Developed from the last of the GP500 racers of 1973, the Pantah and its successors have shown that, contrary to the previously accepted wisdom, a twin can race against the fours and win.

The bike was first shown at the Milan Bike show in December 1979. Milan (Milano Milan (listen) is one of the largest cities in Italy, located in the plains of Lombardy. The prototype was different again to Ducati’s earlier bikes: it had a trellis frame, with the suspended motor acting as a stressed member, the swingarm pivoted on the rear of the crankcase, the SOHC was driven by toothed rubber belt, the primary transmission was via Morse chain and the front disc was a Campagnolo Hydroconico. For the GI Joe character see List of GI Joe ARAH characters. For the Transformers characters see Crankcase (Transformers. Roller chain or bush roller chain is the type of chain most commonly used for transmission of mechanical power on Bicycles Motorcycles The disc brake or disk brake is a device for slowing or stopping the rotation of a Wheel. ^[1] The claimed performance was impressive: 500 cc, 50 hp (36. 5 kW) @ 8500 rpm, 180 kg, 1450 mm of wheelbase, significantly different from the earlier bevel head V twins which were long bulky and stable, and easily surpassed the ill-conceived 1976 parallel twins.

The Pantah came onto the market in 1980 as the red and silver 500SL, with the engine using belt driven camshafts, and a plain bearing crankshaft. The camshaft is an apparatus often used in Piston engines to operate Poppet valves It consists of a cylindrical rod running the length of the Cylinder bank The crankshaft, sometimes casually abbreviated to crank, is the part of an Engine which translates reciprocating Linear It had the same bore and stroke as the old 500 racer, 74 mm x 58 mm, but the head had a 60 degree included valve angle and kept the belt driven camshafts used on the final 500GP engine version. They were noticeably lacking in bottom end and mid range torque, but revved freely enough. The suspension seemed less certain than earlier Ducati models, and the 35 mm front forks lacked rigidity. A motorcycle's suspension is similar to the suspension in an automobile in its purpose Suspension systems serve a dual purpose - contributing to the vehicle's handling and braking for good active

Enthusiasts found the final gearing too tall, and the intake and exhaust restrictive. If you changed those for higher flow items, and lowered the gearing, it gave a performance increase.

Pantah 600SL, 600TL and TT2 racer

In 1981 the silver 600SL became available with fairing and hydraulic clutch activation. A clutch is a mechanism for transmitting rotation which can be engaged and disengaged It had an 80 mm bore and the 58 mm stroke giving 583 cc (The first Pantah based racer,^[2] the 600 cc TT2 racer used 81 mm) By 1984 the last of the 600SL bikes had MHR paint.

In 1982 the 600TL was released, and the styling was promptly panned. The TL only lasted till 1983.

Pantah 650SL and TT1 750 racer

In 1983 the 650SL came about because of the need to homologate the TT1 750 racer’s 61. 5 mm stroke. Instead of producing a production 750, the 650SL was born with 82 mm bore and the required 61. 5 mm stroke. Visually it was the same as the 600SL, but it had more torque, and that was a big improvement. The 650SL produced 63 hp @ 8500 rpm. ^[3]

Cagiva takeover

Cagiva SpA (from CAstiglioni GIovanni VArese) took over Ducati Meccanica in 1985. Cagiva is an Italian Motorcycle manufacturer It was founded in 1950 by Giovanni Castiglioni in Varese, originally producing small metal components Ducati engines promptly appeared in Cagiva-badged motorcycles.

The 650SL continued to be produced after the Cagiva take-over, and ended production in 1986. The Cagiva Alazzurra was a redesigned Ducati Pantah.

For the full history of the ensuing Pantah based motors see Ducati Air-cooled V Twins (1970 on). The next new Ducati engine to appear after the Ducati Apollo was the 90°V twin initial Grand Prix racing versions being 500 cc and the production bikes were 750 cc
