Why You Need This: If you have not figured it out yet, the twin-cylinder engines on the Honda CB350, CB360, and CB450 family bikes vibrate... a lot. This is the nature of an inline twin-cylinder engine with a 180-degree crankshaft. Honda knew this back in the day and attempted to dampen the vibrations by rubber mounting the handlebars from the rest of the bike. Thus the handlebar mounting clamps are isolated from the upper triple tree via cone-shaped rubber dampers. The idea was to dampen any road and engine vibrations from making their way to the hands of the rider for a smooth and comfortable ride.
Well time, as usual, takes its toll on the rubber vibration dampers. This often means that the fit between the handlebars and the triple trees is sloppy and loose, which translates to weird handling and feel when turning your bike. Take back the control of the handling on your Honda CB350, CB360, CB450 and replace the worn-out rubber dampers with our premium "Space Capsule" polyurethane dampeners. Superior to rubber, the polyurethane dampeners are firmer (80 durometer), will not decay, and are made right here in the USA.
Each handlebar mounting clamp uses two dampers, one upper and one lower. These are sold as a kit of four, two uppers, and two lower. The steering on your Honda CB350, CB360, or CB450 can also be improved with a tapered roller steering bearing kit for smoother turning.
CB500T Owners: Due to a manufacturing difference in how Honda cast the triple tree on your bike, these bushings will need a few M12 washers added to properly tighten them when installing on your motorcycles. See our article about the issue right here.
Installation Tip: Install the upper polyurethane dampers on the stems of the handlebar clamps first. Then install the stems into the triple tree and seat the lower polyurethane damper and retaining nut.
