1978 Honda CB750K Open-End & Closed-End Rubber Grips

Two OEM-type rubber grip designs are listed for the 1978 CB750K: closed-end grips and open-end grips with plugs. Both descriptions give the same length and handlebar size. Choose the end arrangement deliberately, then compare the fitted throttle and any bar-end equipment.

1978 Honda CB750K · Grips Buying guide

Choose the grip ends as well as the stated size

The open-end and closed-end listings share replacement references and dimensions, while their ends differ. Use that distinction when comparing the grips with your current control arrangement and bar-end equipment.

Shared references do not erase the end-design choice

Both listings identify references 53165-390-780 and 53166-390-780, but one is closed-end and the other open-end with plugs. Compare the form you need rather than relying on the reference alone. Also check the fitted throttle arrangement if the controls have been changed.

Check accessory requirements separately

An open-end grip provides a different end arrangement from a closed-end grip, but the grip listing does not establish compatibility with every bar-end accessory. Compare any mirror, weight or other equipment with its own requirements, together with the actual handlebar and control arrangement.

Common questions

Are the two grip designs different lengths?

Both descriptions list 130mm length and a 7/8-inch handlebar application. Their stated difference is the end design: closed ends or open ends with included plugs. Compare those details with the controls fitted to the motorcycle.

Does the open-end option include plugs?

Yes. The open-end grip description explicitly includes end plugs. Read that package separately from the closed-end product and check the equipment you intend to use at the bar ends before choosing the design.

Do these grips guarantee a bar-end accessory will fit?

No such accessory compatibility is established by the grip descriptions. Compare the accessory’s requirements with the actual bar and control arrangement. The open-end design and included plugs do not prove that every mirror or weight will fit.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
