Description

A misted-up visor in cold or wet weather is the fastest way to lose sight of the road. This anti-fog insert fits behind the visor on your MT and keeps it clear, so you can ride with the visor shut instead of cracked open.

Which helmets does this fit?

This anti-fog insert is matched to this model:

The helmet model name is printed inside the chin bar, under the lining or on the strap label. If yours isn’t listed, check the visor finder — visors are model-specific and a part from a neighbouring model usually won’t clip in.

How do I fit it?

Take the visor off, clean the inside with a dry cloth, peel the backing and press the insert on from one edge to the other so no air is trapped. No tools needed.

Shipping and returns

Free tracked shipping to the UK, USA and Europe. Delivery estimates are shown at checkout. If it’s not right, you have 30 days to send it back — see our returns policy.

Aftermarket part, not OEM. MT model names indicate fitment compatibility only — we are not affiliated with or endorsed by MT. Confirm your exact model before ordering.

    Delivery 11 days by Nova Poshta. Quality like the original, even the markings are present, maybe they are sold as original, but the price in Ukraine is much higher for such a visor. Fit fine on the MT Braker SV helmet. Overall first impression is positive, well see how it holds up.

    Everything is great, fit perfectly. From the inside the visor looks like yellow glasses.

    The item description is true, the visor gets darker on a sunny day.

    I didn’t think I’d get a really good visor peak for this price, it fits all the slots like the original
