After just over a century of one-upmanship by motorcycle manufacturers, beginning with the 1894–1897
Hildebrand & Wolfmüller, the competition to create the fastest production motorcycle reached a truce, with the arrival of the 1999
Suzuki Hayabusa, that lasted about 8 years. A
gentlemen's agreement was made among the major motorcycle manufacturers to
limit the speed of their machines to 300 km/h (186 mph), starting with 2000 models. After the 1999 Hayabusa sent shockwaves by exceeding the
Honda CBR1100XX's record by more than 10 mph (16 km/h), and rumors and leaks from Kawasaki hinted that their upcoming 2000
Ninja ZX-12R would pass the 200 mph (322 km/h) milestone, some regulators and politicians in Europe called for an import ban against high speed motorcycles. There were fears that there would be "an outbreak of illegal racing as riders try to break the 200 mph barrier". To preempt regulation and avoid negative publicity, the manufacturers voluntarily ended the race to ever higher speeds. The agreement between them and the other brands has never been officially acknowledged by the manufacturers, though media sources report it via unnamed informants, and by testing the top speed of motorcycles known to be capable of exceeding the arbitrary maximum. So for 2000
Breakaways from the agreement MV Agusta advertised their 2007
F4 R 312 as capable of , hence the "312" in the name, "because MV sees no reason to abide by the manufacturers' agreement ... Politics be damned: MV is Italian and the Italians have a national imperative to make their bikes as fast as possible," in the opinion of motoring journalist Roland Brown.
Cycle World reported that "the same BMW who instigated the 'agreement' in the first place" had broken it with the
BMW S1000RR, whose top speed was reported in July, 2010. The 2013
Ducati 1199 Panigale R was delivered with an electronic speedometer that blanked when the motorcycle exceeded 186 mph (300 km/h), leading commentators to question if Ducati was signaling their withdrawal from the gentlemen's agreement. In 2014, Kawasaki announced that the upcoming
Ninja H2 will have a non-street legal "track-only" version (
Ninja H2R) making that will not have a speed limiter, reaching in testing, but Kawasaki did not specify whether they planned to speed limit the street-legal version, which has about , to conform to the gentlemen's agreement. ==See also==
