About the 1998 Yamaha Royal Star Tour Classic

The drive package on the Royal Star includes a liquid-cooled 1,294 cc (79.0 cu in) (referred to as 1,300 cc) V4 engine. It has four valves per cylinder, overhead camshafts, and shim over bucket valves. The five speed overdrive transmission is part of the engine case and both the engine and transmission share oil. The drive shaft and final drive assembly are built into the left side of the double sided swing arm. Swing arm motion is damped by a monoshock mounted horizontally under the center rear of the frame, forward of the rear wheel. The clutch is of the wet plate design and is hydraulically activated by the left hand lever. The brake system uses two disk brakes on the front and one disk on the right rear. All calipers are of four piston design.
