Yamaha YZF-R1

Yamaha‘s YZF-R1, or R1, is an open class sport bike, or superbike, motorcycle produced from 1998 to the present.


Yamaha introduced the YZF-R1 after reworking the Genesis engine to make it more compact by lifting the gearbox input shaft and allowing the gearbox output shaft to be positioned underneath it. Other automakers adopted the’stacked gearbox.’ The engine was made significantly shorter by compacting it, allowing the wheelbase to be lowered. Because of the improved center of gravity, the frame design was able to position the weight of the engine in the frame to help handling.

The swingarm could be lengthened without jeopardizing the entire wheelbase, which was just 1,385 mm (54.5 in). The engine was supplied gasoline by four 40 mm Keihin CV carburetors. It was outfitted with KYB upside-down 41 mm front forks and 300 mm semi-floating disk brakes. The instrument panel was electronic, and it had a self-diagnosis system and a digital speed readout. Yamaha’s Exhaust Ultimate Power Valve (EXUP) was employed in the exhaust system to manage the exhaust gas flow and enhance engine power generation at all rpm. This resulted in a high-powered, high-torque engine. The Yamaha YZF-R6 superbike was released in 1999 as the 600cc version of the R1.

Aside from paint and cosmetics, the 1999 R1 experienced very minimal alterations. A revised gear change connection was also included, as was an increase in the length of the gear change shaft. The reserve fuel tank capacity was lowered from 5.5 to 4.0 L (1.21 to 0.88 imp gal; 1.5 to 1.1 US gal), although the overall fuel tank capacity remained constant at 18 l (4.0 imp gal; 4.8 US gal).

Motorcycle Consumer News tests of the 1998 model year YZF-R1 produced a 0 to 60 mph (0 to 97 km/h) time of 2.96 seconds, a 0 to 100 mph (0 to 161 km/h) time of 5.93 seconds, a 0 to 14 mi (0.00 to 0.40 km) time of 10.19 seconds at 131.40 mph (211.47 km/h), and a top speed of 168 mph (270 km/h), with decel (34.7 m). Cycle World testing for the 1999 model year revealed a 0 to 60 mph (0 to 97 km/h) duration of 3.0 seconds, a 0 to 14 mi (0.00 to 0.40 km) time of 10.31 seconds at 139.55 mph (224.58 km/h), and a peak speed of 170 mph (270 km/h).
