Motorcycle handlebar end caps designed to protect and tidy bar ends with a secure, expandable fit. Riders who value neat finishing touches and reliable protection will appreciate the straightforward design. Are TUCKBOLD Handlebar End Caps the right fit for your 18–19mm hollow handlebars?
⚡ At a Glance
- • Durability: CNC aluminium alloy construction, resistant to rust, deformation and breakage
- • Best for: Owners of motorcycles with hollow handlebars that have an 18mm to 19mm inner diameter
- • Not ideal for: Solid handlebars or bars with inner diameters outside the 18–19mm range
Expandable screw-in end caps machined from CNC aluminium alloy fit hollow handlebars with an inner diameter of 18mm to 19mm. Supplied as a pair and secured by tightening a central screw that expands the plug to hold it in place.
Secure, rattle-free fit - thanks to expandable screw insert
A central screw is tightened to expand the inner plug inside a hollow handlebar, creating radial pressure against the inner wall to lock the cap. The expansion mechanism relies on the screw drawing the insert outward as it tightens.
Caps stay firmly seated and resist loosening and rattling during normal riding, keeping bar ends secure.
Long-lasting protection - with CNC aluminium alloy construction
CNC machining produces precise, uniform parts from aluminium alloy which reduces weak points. The chosen alloy resists rust and is designed not to deform or break easily.
Handlebar ends gain durable protection from knocks and wear, helping preserve the bars' appearance over time.
Straightforward installation - with simple screw-in fitting
Screw into the existing handlebar insert and tighten with a tool to expand the plug so it locks in place. The package contains a pair, while a driver or similar basic tool is required and is not included.
Fitting can be completed at home with basic tools, making it a quick upgrade for routine maintenance or restoration.
