Yamaha launched the original R1 in 1998 to go up against the fastest sportsbikes of the day, the Honda Fireblade and Ducati 916. In 2000 it recieved detail changes including sharper styling and a 2kg weight reduction.
The 2002 version was a new model which featured fuel injection, angular styling and a new chassis. This model lasted just two years before being superceded in 2004 by a new version with underseat pipes, a new chassis, braced swingarm and more power.
This version of the R1 recieved a few changes in 2006 including a longer wheelbase and a limited edition SP version was made available with Ohlins suspension, Marchesini wheels and a slipper clutch.
In 2007, Yamaha scrapped their five valves per cyclinder engine format in favour of a four-valve head version. The bike got more power, ride-by-wire, electronically-controlled inlet trumpets and a new chassis and styling.
A major change came in 2009, when the engine was changed for a crossplane crank design to create more grunt lower down the range. This version also got a new chassis and styling and had detail changes including six-stage traction control in 2012.
