NSR Big Banger... the engine firing order courtesy the Big Bang RVF750 V4 4 stroke...
Someday I predict all of the Gp bikes will be V4s... after all it sports the most
advantages in MotoGp... just as Rossi...
Horsepower: 168bhp @ 13,000rpm

Honda’s NSR was the most successful of the 500cc two-stroke Grand Prix
missiles, and frequently the most scary too. That was mainly due to its V4
engine, which was generally the most powerful on the grid - and sometimes so
vicious that the world’s best riders couldn’t control it.
The NSR was debuted in 1984 by Freddie Spencer, who’d won Honda’s first
500cc title the previous year on the sweet-handling NS500 triple. The
liquid-cooled V4 was a much nastier device. It differed from Suzuki and
Yamaha’s V4s by having a single crankshaft, instead of twin contra-rotating
cranks. The reduced friction aided power: the first NSR’s 144bhp was purely
awesome in 1984.
Fast Freddie won the championship in 1985, and Wayne Gardner followed in
’87, by which time the V4’s breathing had been improved by increasing
cylinder angle from 90 to 112 degrees. Eddie Lawson regained the title for
Honda in ’89 - after the NSR’s evil-handling chassis had been reinforced in mid
season to cope with an engine by now producing 162bhp.
Honda’s V4 ruled the Nineties, with five titles for Mick Doohan plus one for
Alex Criville. Along the way it went to “big-bang” firing order (cylinders firing in
quick succession for added traction) then back to “screamer”. In 2000 even
Valentino Rossi couldn’t tame a NSR that had been tuned to make almost
200bhp. By the time Rossi took the final 500cc crown in 2001, the NSR had
won 130 GPs and ten world championships in 18 years. It was the most
dominant two-stroke Grand Prix engine ever created, made the MotoGP bikes
that replaced it seem utterly bland in comparison, and scarred a lot of brave
men in the process. To this day, the NSR500 engine is the maddest thing ever
Yep... they really did thanks to Mick Doohan...Wow, they really made a Big Bang RVF750?
