Yamaha YZF-R1 1998–1999
Yamaha launched the YZF-R1 after redesigning the Genesis engine to offset the crankshaft, gearbox input and output shafts. This "compacting" of the engine yielded a huge dividend in that the total engine length was now much shorter. This allowed the wheelbase to be shortened significantly which resulted in much quicker handling and an optimized center of gravity. The bike had a compression ratio of 11.8:1. with a 6-speed multi-plate clutch transmission.
The launch model Yamaha YZF-R1 was available in white/red or blue. Early models were subject to a worldwide recall for a clutch problem. Yamaha today describes the launch of the R1 as the true value of "Kando".
YZF-R1 instrumentation
The 1999 R1 saw only minor changes apart from paint and graphics. Notable improvements were a redesigned gear change linkage and the gear change shaft length which was increased for better gear shifting. Fuel tank reserve capacity was reduced from 5.5 l (1.2 imp gal; 1.5 US gal) to 4.0 l (0.88 imp gal; 1.1 US gal), while the total fuel tank capacity was unchanged at 18 l (4.0 imp gal; 4.8 US gal). A second worldwide recall was issued for 1998 and early 1999 models to change a coolant hose clamp under the fuel tank which could, under hard use, come adrift.
