Paton S1 17 February 15

Paton Moto started producing racing bikes in 1958 by founders Guiseppe Pattoni and Lino Tonti after a pact in 1957 when some of the top Italian bike manufacturers decided to quit racing. The name of the company came from the first three letters of their last names and their first racer was ridden by Mike Hailwood at the TT. They continued to build race bikes through the decades and in 2010 they built the prototype for a road legal version, it was named the S1.

The S1 in now in production and is available in four versions which have varying specifications and prices:

The Standard starts at €16,000
The Classic TT starts at €18,500
The PEP Memorial starts at €21,000
The 1º Factory Signature starts at €23,000

The bikes are hand-made in the Paton factory in Settimo Milanese Italy and you can get the S1 with different options including the fairing and lighting. All the bikes, apart from the Standard, are only available in limited quantities and they are available in any color you want, as long as it is green.

The space-frame chassis is made with high strength steel tubes of 30mm diameter TIG welded. The frame of standard versions is gloss black powder coated. The space-frame chassis is necessary to place the air box in the best position and shows the relationship between classic and modern through the use of round tubes, as those of the 60’s twin-cylinder 4-stroke racer.

The main structure of the swingarm is made from a sheet of 4mm thick aluminum, laser cut, shaped and welded. Some parts machined from solid; the slides of the wheel axle, the lugs for the shock absorbers and the bearing seats of the swing arm pivot, all parts are assembled for welding. The design is finished, sizing carefully and rounding the edges of the entire structure in order to maintain classic lines.

Fork yokes
The fork yokes show the same design of the original-ones fitted on the twin cylinder racer of the ‘60s, they are still aluminium, but the difference between them lies in manufacturing system: once they were cast, now items fitted on the S1 model are CNC machined from billet.

Exhaust system
The exhaust system was completely revised by Paton technicians in order to follow a mix of classic and modern style: it’s entirely made of stainless steel, fitted with catalyzers and a silencer positioned underneath the engine, expressly shaped and sized with the aim to keep a slenderness to the bike. The system is finished with a couple of vintage-shaped rear-silencers, one each side, very similar to those fitted on the Paton racer of the 60’s/70’s.

Fuel tank
The fuel tank, completely made of aluminum, has been the subject of extensive studies to obtain a capacity of 17 liters and to maintain a line and a slenderness similar to those of the model racing in the 60s and 70s. To recover the space "stolen” from the airbox, positioned above the head for injection engines, the tank was lengthened in the area under the seat to maintain a classical style.

For the Paton S1 the front suspension has been designed with a vintage look and a high tech content in mind. The design of the bike demands traditional suspension, which has been designed by Paton and is built by specialized suppliers with high-end CNC machines.

Wheels and brakes
The wheels and brakes have a "classic look with a tech content" with with Paton's own design, painted in magnesium, and FaBa rims with tubeless tyres. The ventilated disk brakes are produced by Technobike for the Superbike championship.

For the first road Paton they have used the 650cc engine from Kawasaki ER6; this choice is the result of consideration for the technical specifications that Paton want for the S1, and of the requirements necessary to to obtain the road use registration. The Kawasaki 650cc is, for size and specs, the modern engine that most resembles the Paton's four stroke engines from 1960. The engine, with 75Hp at the wheel works well on a bike that weights 155kg, 50Kg less than the Kawasaki it comes from.
