side "parking" lights within the twin-headlight panel, giving a more angular appearance. This also provided additional aftermarket possibilities, such as the removal of the front turn signals and the repurposing of the parking lights as directional or hazard markers while stopped. In 2002, Cycle World reported fuel mileage of , a time of 2.9 seconds, a time of 10.32 seconds at , and a top speed of . For 2003, the only change was the addition of hazard warning lights and low-beam headlights, which stay on when the engine is running. 2004–2005 With the competition advancing, Yamaha made some major changes to the R1. This included style updates, like an underseat dual exhaust, and performance upgrades including radial brakes, and, for the first time, a ram-air intake. Furthermore, earlier models' tendency for wheelies was reduced by changing the geometry of the frame and weight distribution. The all-new engine was no longer used as a stressed member of the chassis, and had a separate top crankcase and cylinder block. The 2004 R1 weighs dry. The conventional front brake calipers were replaced by radially mounted calipers, activated by a radial master cylinder. A factory-installed steering damper was also added in 2004. Combined with the changes to the frame, this helped to eliminate the tendency of the handlebars to shake violently during rapid acceleration or deceleration on less-than-perfect surfaces, a phenomenon known as speed wobble or a tank slapper. Motorcycle Consumer News tests of the 2004 model year YZF-R1S yielded a time of 3.04 seconds and of 5.42 seconds, a quarter-mile time of 9.90 seconds at , and a top speed of . 2006 The R1's swingarm was extended by to reduce instability during acceleration. That year, Yamaha also released a limited edition version, the LE, in original Yamaha racing colors to celebrate its 50th anniversary. The LE and SP models had custom Öhlins front and rear suspension units developed by the same team as the YZR-M1 MotoGP bike. Custom forged aluminum Marchesini wheels specifically designed for the LE shaved nearly a pound off the bike's unsprung weight. A back torque-limiting slipper clutch and an integrated lap timer rounded out the package, essentially making the LE a production racer. Only 500 units were made for the United States, with another 500 units for Europe. 2007–2008 An all-new YZF-R1 for the 2007 model year was announced on 8 October 2006. It had an all-new
