Complete lower handlebar riser. Not just a spacer.
In addition to raising the height of your Xchallenge handlebars by some 15 mm, you can reposition the handlebars forward or rearward. For the taller rider, moving the bar up and forward means less strenuous riding when standing and thus an increase in endurance and concentration. This makes fast and difficult tracks easier to master. Ideal for sporty off-road use. Works on ABS model but installation is a bit more complicated; need to remove upper triple clamp.
