The steering stem rides in upper ball bearings and lower tapered roller bearings (early YZ80 models) or tapered roller bearings (all other models). The front suspension uses one of three basic designs: damper rod, bottom cartridge, or top cartridge. The rear suspension consists of a single shock absorber with concentric coil spring, a swingarm and progressive rising rate suspension linkage. The suspension linkage causes the suspension to stiffen as its travel increases. This allows a softer ride over small bumps in the terrain, together with firmer suspension control over large irregularities. HANDLEBARS REMOVAL, INSPECTION AND INSTALLATION (Refer to illustrations 2.3a and 2.3b).

The handlebars rest in brackets on top of the upper triple clamp. If the handlebars must be removed for access to other components, such as the steering head bearings, simply remove the bolts and take the handlebars off the bracket. It is not necessary to disconnect the throttle or clutch cables, brake hose or the kill switch wires, but it is a good idea to support the assembly with a piece of wire or rope, to avoid unnecessary strain on the cables. If the handlebars are to be removed completely, refer to Chapter 2 for the clutch lever removal procedure, Chapter 4 for the throttle housing removal procedure, Chapter 5 for the kill switch removal procedure and Chapter 7 for the brake master cylinder removal procedure. Remove the upper bracket bolts, lift off the brackets and remove the handlebars (see illustration).
