22→25 mm Handlebar Adapter Sleeve – 1.5 mm Wall Thickness

Mount your 25 mm controls securely on a 22 mm handlebar

Upgrading your handlebar, modernizing your cockpit, or combining components from different manufacturers? This 22→25 mm adapter sleeve (1.5 mm wall thickness) provides a clean and reliable solution for installing 25 mm controls (switch housings, master cylinders, clutch levers, perches) on a 22 mm handlebar. Designed for a precise outer diameter conversion, it ensures uniform clamping with no play or damage to the handlebar finish.

Machined from durable solid brass, the sleeve offers both rigidity and installation tolerance. It fits perfectly over a 22 mm tube while providing a 25 mm outer diameter so that your clamps and controls tighten exactly as intended. No more improvised solutions with tape or makeshift spacers—just a precise, durable and professional fit.

Installation is quick and straightforward: slide the sleeve onto the desired clamping area, trim it to length if necessary with a simple straight cut, position your control, and tighten to the recommended torque. The result is an aligned, secure and stable installation, whether for everyday riding, touring, or a premium café racer build.

Why Upgrade from Homemade Solutions?

Without a dedicated adapter sleeve, installing 25 mm controls on a 22 mm handlebar often leads to makeshift fixes such as tape or soft spacers, which cannot guarantee proper alignment or long-term reliability. The result can be unattractive, imprecise, and potentially unsafe during heavy braking or aggressive riding.

• Clamping play and risk of master cylinder rotation

• Damage to the handlebar coating or finish

• Poor positioning affecting rider ergonomics

• Premature wear of clamps and controls

With this 22→25 mm brass adapter sleeve, you get a rigid, precise and long-lasting interface that eliminates these issues. The exact outer diameter allows your controls to clamp exactly as designed, providing a solid, perfectly aligned and comfortable cockpit setup.

Ideal Applications:

• Converting 25 mm switches, master cylinders and clutch levers to fit 22 mm handlebars

• Café racer, bobber and scrambler custom projects

• Installing aftermarket controls on motorcycles equipped with 22 mm handlebars

• Reversible installations requiring a clean, glue-free solution
