YAMAHAYZF-R1 Superbike 2007 - 2010

　　The Yamaha YZF-R1, also known as simply R1 was a sports motorcycle manufactured by Yamaha in 1998 and powered by a 998cc engine. The bike received significant updates over its production run.

　　In 2000, the motorcycle received its first modifications and minor design changes that improved its capabilities. Although the power output was unchanged, the engine came with a revised management system that offered smoother and broader power distribution. The bike's bodywork was similar to the previous model, with a reshaped headlight housing, more aerodynamic side panels, and a reshaped windscreen for better protection, resulting in a three percent drag force reduction.

　　The 2002 model came with a new fuel injection system with a CV carburetor slide controlled by the engine vacuum and a power output similar to its predecessor. One significant improvement to the 2002 machine was the silicon content cylinder sleeves that reduced thermal distortion and oil consumption.

　　For the 2004 model, Yamaha made some significant changes that included an under-seat dual exhaust system, a radial braking system, and a ram-air intake for the first time. The bike's geometry was changed, and the engine was no longer used as a stressed chassis member.

　　In 2007, Yamaha released a new YZF-R1 machine with an all-new engine that packed four-valve per cylinder instead of the five-valve layout. Also, the bike came with a Yamaha Chip Control Intake (YCC-I) variable intake funnel system, Yamaha Chip Control Throttle (YCC-T) fly-by-wire system, a slipper clutch, a new aluminum Deltabox frame, and a new swingarm.

　　The 2007 Yamaha YZF-R1 came equipped with a 998cc four-stroke four-cylinder liquid-cooled powerplant, boasting 180 hp at 12,500 rpm, 189 hp with max ram air, and 113 Nm (83 lb-ft) torque at 10,000 rpm and 118 Nm with max ram air.
