Early versions had conventional suspension, consisting of hydraulically damped telescoping front forks and dual coil-over shocks at the rear. Later versions had air-assisted forks and featured Honda's Pro-Link monoshock rear suspension. US bikes (except GL500I, GL650I and Turbo) were equipped with a single front disc brake whereas all other bike possess dual front disc brakes. Models after 1980 sport dual piston calipers replacing the single piston caliper of the earlier models. For the Turbo and Eurosport models the rear drum was replaced with a dual piston caliper and disc. All models feature steel tube frames with a large backbone, with the engine used as a stressed member. The dual shock models use a single tube backbone whereas the later Pro-Link models employed a triple tube backbone. Later models are blessed with larger front forks and a factory installed fork brace which provides a noticeable improvement in handling.
