Handlebars provide a mounting place for controls such as brake, throttle, clutch, horn, light switches and rear view mirrors; and they help to support part of the rider's weight.
[1][2] Handlebars are made from round-section metal tubing, typically aluminium alloys or chrome plated steel but also of carbon fibre and titanium, shaped to the desired contour.
Risers hold the handlebars above their mounting position on the upper triple clamp[3] or the top of the fork, and may be integrated into the bar itself or separate items.
Each handlebar end may contain bar-end weights to damp vibration by isolating the bar's resonant frequency from that of the engine.
[4] Electrically heated grips may be fitted to provide warmth for the rider in cold weather.
