The MT Streetfighter SV S is a free-spirited convertible helmet for riders who face life head-on — and it is genuinely four helmets in one: streetfighter or jet, with or without the visor, so you choose the style to suit the moment. Wearing the Belic B2 graphic in matt grey, it sails through the demanding ECE 22.06 standard and, in its latest update, adds refreshed interiors for even more comfort.
Key Features
- 4-in-1 convertible — removable chin guard and removable visor for four style combinations (streetfighter/jet, with/without visor)
- ECE 22.06 and DOT — top-level safety, surpassing the current European standard
- HIRP shell for an optimal balance of safety and weight (~1.5 kg)
- Integrated sun visor as standard; a wide range of visor colours sold separately
- SportCam mount included as standard for an onboard camera
- Vent covers supplied as standard to block air or water in the rain
- MT-MDTC micrometric double-tooth closure; Bluetooth intercom compatible
- Renewed, fully removable and washable interior with improved fabrics
Four Helmets in One
The Streetfighter SV S is built around versatility. Remove the chin guard for an open, jet-style ride; keep it on for more coverage. Run the visor or take it off for a raw streetfighter look. Four configurations, one helmet — pick whichever suits the ride, the weather or your mood.
Safety, Ventilation and Camera
The HIRP shell exceeds ECE 22.06 and holds DOT approval, with the reliable MT-MDTC double-tooth micrometric buckle. Ventilation runs through front and top inlets to rear exhausts, and the included vent covers seal things up in the wet. A standard SportCam mount makes fitting an action camera clean and simple.
An Honest Word on What This Helmet Is
The Streetfighter SV S is about style and versatility more than outright touring comfort. Its convertible, open-friendly design and standard sun visor make it a superb urban and short-hop helmet; on long motorway stints an open configuration will be breezier and louder than a sealed full-face — which is exactly the trade you choose when you want an open, streetfighter feel. It is homologated to ECE 22.06 and DOT for road use.
Comfort and Interior
The latest interior overhaul brings new linings and improved fabrics — fully removable and washable — for a fresh, comfortable fit. Bluetooth intercom compatibility means adding communication is straightforward.
The Belic B2 finish
Belic B2 wears the free-spirited Belic graphic in matt grey — urban, understated and easy to match.
Finding Your Size
The Streetfighter SV S is available in XS to XXL. Measure your head circumference with a soft tape about 1–2 cm above the eyebrows, around the widest part of the skull, and compare it with the size chart linked on this page. Between sizes, choose the larger for comfort.
Approved Use
The MT Streetfighter SV S is a unisex convertible helmet homologated to ECE 22.06 and DOT, designed for urban and street riding.
