STU r3115M supplementary rear-view mirror for motorbikes

Round CNC-machined aluminium handlebar-mounted rear-view mirrors – under-handlebar fitment, pair Do you want to radically change the look of your motorbike, free up the ends of the handlebars and achieve a clean, custom design? These premium round CNC-machined rear-view mirrors are designed for standard handlebar mounting, but with the option to rotate the joint so that the mirrors sit beneath the handlebars (under your hands). This gives your motorbike a more aggressive, ‘drag style’ or clean ‘bobber/café racer’ look, without having to fit bar-end mirrors.

The mirrors are fully machined using precision CNC technology from high-quality aerospace-grade aluminium, ensuring extreme strength, resistance to vibration and a luxurious finish. Key product features:

Premium CNC machining: Made from high-strength aluminium with an anodised finish that offers excellent weather resistance, won’t fade in the sun and won’t corrode.

Clean and aggressive custom look: Mounting the mirrors beneath the handlebars gives your motorbike an extremely low profile, which perfectly complements minimalist conversions (Bobber, Café Racer, Scrambler, Custom, Cruiser).

Exposed handlebar ends: Thanks to handlebar mounting (e.g. into standard M8/M10 threads), you can retain the original bar weights and grips, or fit blasters and exposed handlebar ends.

Fully adjustable 360° angle: Thanks to the swivel joint, you can adjust the mirrors precisely to the position that suits you – above or below the handlebars, at the angle you need for a clear view.

Stable, vibration-free image: The robust construction and secure mounting minimise lens shake even at higher speeds. Wide compatibility:

The mirrors are universal and fit most motorbikes with standard mounting threads for handlebar-mounted mirrors (M8 / M10 thread). They are ideal for:

Custom builds: Bobbers, Café Racers, Scramblers, Choppers, Cruisers (e.g. Harley-Davidson, Honda Shadow/VT, Yamaha Dragstar, Suzuki Intruder, Kawasaki VN / Vulcan)

Installation tip: After fitting the mirrors under the handlebars, check that they do not interfere with the levers (brake, clutch) and that you have a clear view even over your hands. This may require minor adjustments to their position. On retro builds, the handlebars are often changed as well, which may affect your view.
