engine measure for the first time, instead of the 56x50,6 ( bore x stroke ) configuration used in previous Paton bikes.
In 2000, the PG500R used a double beam aluminum frame and a swingarm from "Paton LM Gianetti" whilst in 2001, the PG500RC switched to a "Paton Cagiva V 594 in Anticorodal material" and also changing the livery slightly.
Despite the death of Roberto Pattoni's father Giuseppe Pattoni 1999, Roberto continued to develop the teams racing motorbikes, but the team would score only one point in the 2000 Grand Prix motorcycle racing season as a wildcard entry, when Paolo Tessari finished fifteenth at the Sachsenring on the teams PG500R machine.
[1] With the arrival of the 4 stroke and highly expensive MotoGP, which allowed for a double capacity (1000cc) and with the clear intent to push for the 2 stroke retirement by the FIM, Roberto Pattoni and his team decided to pull out of grand prix motorcycle racing after the 2001 season, mainly due to the ever rising costs in the sport which were needed to create a new 1000cc 4-stroke MotoGP bike, that the Paton team did not have the budget for.
[2] During this season, Paton was sponsored by Slovnaft thanks to the wildcard rider Vladimír Častka, but failed to score any points due to the retirement of Shaun Geronimi at the 2001 Czech Republic motorcycle Grand Prix, the two DNQ's of Vladimír Častka at the 2001 Spanish motorcycle Grand Prix and 2001 Italian motorcycle Grand Prix and the withdrawal of Sébastien Gimbert from the 2001 British motorcycle Grand Prix after he crashed 20 minutes into the first practice session and broke his ankle.
