How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure.
It is important that the tape measure runs around the widest part of the head – only then will you get a correct result.
Place the tape measure at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears. At the back, the tape must run over the largest part of the back of the head.
Make sure the tape sits snugly but does not dig in. Measure 2–3 times for the most accurate result, then compare the value in centimetres (cm) with our size chart.
Tips for an accurate result
- Keep hair flat
- Keep the tape horizontal, along the largest circumference
- Do not measure too loosely
- For values between two sizes: usually choose the larger size
Important note on fit
The right helmet should fit firmly without uncomfortable pressure points. A new helmet may feel a little tighter at first, as the inner lining adapts slightly over time.

The MT Viale SV S is a lightweight urban open-face (jet) helmet built for everyday city and scooter riding. It keeps things simple and practical while covering the essentials properly: ECE 22.06 and DOT safety passed with all included accessories, an integrated drop-down sun visor, a removable washable interior and intercom readiness — at a genuinely accessible price. Wearing the Tasty C4 graphic on a bright gloss silver base, it's an easy, no-fuss helmet for daily commutes.
Key Features
- ECE 22.06 and DOT certified — passed with all included accessories
- HIRP (High Impact Resistant Polymer) shell, light at approx. 1.2 kg (MT)
- Integrated drop-down sun visor for instant glare protection
- MT-V-26B visor — clear included; dark and iridium mirror visors available separately
- MT-Micrometric+ closure with a minimum two-tooth anchorage
- Removable, washable interior; intercom-ready
Shell and Safety
The Viale SV S is built on an HIRP (High Impact Resistant Polymer) shell — light but tuned for effective impact absorption. It is homologated to ECE 22.06 and approved to DOT, and MT states it passed certification with all of its included accessories fitted. The MT-Micrometric+ buckle guarantees a minimum two-tooth anchorage for a quick, secure, glove-friendly fastening.
Visor and Sun Visor
The Viale SV S comes with the MT-V-26B clear visor as standard, and adds a full integrated drop-down sun visor that deploys on a slider to cut glare, then retracts into the shell — a feature usually reserved for pricier helmets. Dark and iridium-mirror MT-V-26B visors are available separately to personalise the look and match the light you ride in.
An Honest Word on What This Helmet Is
The Viale SV S is a straightforward, affordable open-face (jet) helmet made for the city. It's light and easy to live with, but it's honest about its brief: it does not cover the chin like a full-face, MT does not fit it with an active ventilation system or a Pinlock-ready visor, and open-face helmets are inherently airier and noisier at higher speeds. For urban and scooter riding at city speeds — its intended use — it's exactly the right tool, homologated to ECE 22.06 and DOT.
Comfort, Interior and Intercom
The interior is fully removable and washable, so a helmet you wear every day stays fresh and hygienic. MT lists the Viale SV S as intercom-compatible, with speaker room to add a communicator for calls and navigation on the commute.
The MT-Micrometric+ Buckle
The Viale SV S fastens with MT's MT-Micrometric+ micrometric buckle — a ratchet-style closure you set to your neck once, then click open and shut with one gloved hand every time you ride. Unlike a double-D ring it needs no re-threading, and its minimum two-tooth anchorage keeps the strap securely locked. It's the most convenient closure for a helmet you take on and off constantly on the commute.
Care and Everyday Practicality
Because the interior lifts out, you can wash the cheek pads and crown liner to keep the helmet fresh through a season of daily use, then refit them in minutes. Wipe the shell and visor with a soft, damp cloth and a helmet-safe cleaner — never solvents, which can craze polycarbonate. Replace the visor promptly if it becomes scratched, as a compromised screen is both a visibility and a safety issue.
Who It's For
The Viale SV S is aimed squarely at city and scooter riders who want a light, comfortable, properly certified open-face at an accessible price — a first helmet, a second lid for commuting, or an easy everyday option for short urban hops. If you spend most of your time at town speeds and value quick on-off convenience and a built-in sun visor over touring features, it's an ideal match.
Design and Colour — The Tasty C4 gloss silver finish
Tasty C4 lifts the Viale SV S out of plain solids with a light gloss silver shell and a contrast accent stripe — a fresh, contemporary look that still stays easy to pair. The silver keeps things light and modern without shouting.
A clean silver base with a graphic accent under gloss: more character than a plain solid, but still versatile enough for daily city use. A smart pick for riders who want a bit of style on a lightweight commuter jet.
Finding Your Size
This colourway is available in XXS–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 two sizes, choose the larger for everyday comfort.
Approved Use
The MT Viale SV S is a unisex open-face (jet) helmet homologated to ECE 22.06 and DOT, designed for urban and scooter riding.
