MotoGP按排气量的大小分为MotoGP级别（1000cc）、Moto2级别（600cc 取代了原来的GP250级别）和Moto3级别（250cc 取代了原来的GP125级别）这3个级别。现在全部级别都采用四行程引擎。，即每站都有三组赛事。其中Moto GP组就是由GP500升级转变而来，主要的变化就是由原来二行程500毫升引擎转换成990毫升四行程引擎。从这项改革措施在2000年被国际摩联(FIM)正式确认并执行后，MotoGP在摩托车赛事的地位就等同于F1目前在方程式赛车中的地位了。
Boasting 63 years of history, MotoGP™ is the oldest of all motorsports World Championships - its first annual competition having been held in 1949.
From the early 1900s motorcycle Grands Prix were held in various countries and in 1938 the predecessor to the current FIM, the FICM (Fédération Internationale des Clubs Motocyclistes), announced a European Championship. However, the start of the Second World War interrupted the competition and it then took some time after the war for fuel to become available, before a truly international series could be created.
When the first formal World Championship was held in 1949 Grand Prix racing comprised four solo classes, with the inaugural ‘premier class’ 500cc title being won by British rider Leslie Graham on AJS machinery. Another Brit, Freddie Frith (Velocette) took the first ever 350cc World title, while Italians Bruno Ruffo (Moto Guzzi) and Nello Pagani (Mondial) were the first 250cc and 125cc World Champions respectively.
A 600cc sidecar championship in the same season was won by Britons Eric Oliver and Denis Jenkinson with Norton machinery, though the sidecar category became a 500cc competition in 1951.
The Italian manufacturers such as the aforementioned Mondial and Moto Guzzi firms, along with companies such as Gilera and MV Agusta, dominated the World Championships during the 1950s, reflecting the strength of the country’s motorcycle industry at the time. MV Agusta were particularly prolific late in the decade, taking a clean sweep of World titles across all four categories for three seasons from 1958 to 1960 – while their dominance in the 500cc class was unbroken for 17 years from 1958 until 1974.
THE SWINGING SIXTIES
During the ‘60s the Japanese motorbike industry began to boom and during that decade many of the manufacturers that participate in modern day MotoGP™ racing, such as Honda, Suzuki and Yamaha, arrived to pick up their first World Championship title wins across the 125, 250 and 500 categories, as they announced themselves in Grand Prix racing. Suzuki in particular enjoyed great success in a new 50cc class which was introduced in 1962.
The late ‘60s brought the start of the glory days for MotoGP™ Legend Giacomo Agostini – the most successful rider in the history of World Championship competition. Up until the modern era riders regularly competed in two or three classes simultaneously and Agostini took 10 of his 15 titles in five successive seasons as double champion in 350cc and 500cc - in a golden period commencing in 1968, riding for MV Agusta.
国外网站大全At this time the escalating costs associated with Grand Prix racing had reached such a level that several Japanese firms withdrew from competition - with only Yamaha left at the end of the ‘60s. In response the FIM introduced rules which limited the bikes to single cylinder engines in the 50cc class, two cylinders in 125cc and 250cc, and four cylinders in 350cc and 500cc.
