The 1998-2003 Yamaha YZF-R1 sportbike repair manual by Haynes covers European and U.S.A. models.
The Yamaha YZF-R1 uses a 998cc liquid-cooled, 20V in-line four cylinder engine with EXUP (EXhaust Ultimate Powervalve) system. Dual Overhead Cams (DOHC), chain-driven from the right-hand end of the crank. Transmission is six-speed constant mesh.
Note: The Yamaha YZF1000R is covered in Haynes manual 3720.
This open class sport bike was launched to introduce an engine that was more compact because the gearbox input shaft was raised and the gearbox output shaft was placed underneath it. The stacked gearbox shortened the engine's overall length. The 302 pages of this Haynes manual is packed with illustrations that cover the repair and maintenance of the frame, suspension and final drive, including installation and removal of the swingarm; the brakes, wheels and tires, including inspection of the brake hoses and unions. Learn about proper methods of security and storage for the Yamaha YZF-R1 as well as important troubleshooting tips.

FRAME, SUSPENSION AND FINAL DRIVE
SWINGARM - REMOVAL AND INSTALLATION
BRAKES, WHEELS AND TIRES
Note: Before removing the swingarm, it is advisable to perform the rear suspension checks described in Chapter 1 to assess the extent of any war.
- Removal the front sprocket (see Section 16), the rear wheel (see Chapter 7), and the rear shock absorber (see Section 10).
- Unscrew the bolts securing the rear hugger to the swingarm and remove it, noting how it fits (see illustrations). If required, unscrew the bolts/trim clips securing the chainguard to the swingarm and remove it, noting how it fits.
- Unscrew the bolts securing the brake hose guides/clamps to the swingarm (see illustration). On 1998 to 2001 models, feed the brake caliper through the swingarm (see illustration).
Secure the caliper to the frame with a cable tie, making sure no strain is placed on the hose.
- Before removing the swingarm it is advisable to recheck for play in the bearings (see Chapter 1). Any problems which may have been overlooked with the other suspension components attached to the frame are highlighted with them loose.
BRAKE HOSES AND UNIONS: INSPECTION
- Brake hose condition should be checked regularly and the hoses renewed at the specified interval (see Chapter 1).
- Twist and flex the rubber hoses while looking for cracks, bulges and seeping fluid (see illustration). Check extra carefully around the areas where the hoses connect with the banjo fittings, as these are common areas for hose failure.
- Check the banjo union fittings connected to the brake hoses. If the union fittins are rusted, scratched or cracked, fit new hoses.
- The brake hoses have banjo union fittings on each end. Cover the surrounding area with plenty of rags and unscrew the banjo bolt at each end of the hose or pipe, noting its alignment (see illustration).
Free the hose from any clips or guides and remove it, noting its routing. Discard the sealing washers on the hose unions.
