ACS updated the ever popular Rotor 45 Stem and solved what became a problem with the ACS Rotor - The stem had to be raised considerably to allow the Rotor to operate correctly. The ACS Rotor 55 Stem had a Specially Angled Forged Aluminium Head position. This lowered the handlebars without losing the stem shaft height required to run the Rotor and aided responsiveness and control. The ACS Rotor 55 Stem also came with a built-in adjustable rear cable guide and a hollow chrome moly stem bolt.

Unfortunately, these also became famous for the hairline cracks that would appear in the clamp bolt holes where the stem slants downwards.
