Riders' Guide
How to choose the right helmet (a simple, honest guide)
20 June 2026 · 5 min read · by the Speed World team
A helmet is the most important thing you'll buy for your bike — and the easiest to get wrong. Here's how we'd guide our own family. Get four things right and you can't go far wrong: type, certification, size and fit.
1. Pick the right type for your riding
Full-face gives the most protection and is best for highway speeds and daily city riding. A flip-up (modular) gives you full-face safety with the convenience of lifting the chin bar at a signal. Open-face is airy and easy for short, slow city runs but leaves your chin exposed. Off-road helmets are light and ventilated with a peak, made for trails.
2. Insist on ISI certification
In India, a helmet must carry the ISI mark — it's the legal safety standard. A cheap, uncertified lid is not a helmet, it's a costume. Every helmet we sell carries the genuine ISI mark, and we'll show it to you.
Tip from the shop: Fakes and uncertified lookalikes are common in the market. If a price looks too good to be true, it usually is. Buy from someone who shows you the certification.
3. Get the size right
Measure your head and match it to a size chart before you shop — it saves a lot of guessing. We've put together a simple one you can use at home.
When you're between two sizes, choose the smaller; the cheek pads break in slightly with use.
4. Try the fit — it's the whole game
Sizes vary a lot between brands, so the chart gets you close, not perfect. A correct helmet is snug all around, doesn't slide when you shake your head, and has no painful pressure points after a few minutes. This is exactly what we help with in the shop — we'll put two or three brands in your size on your head until one feels right.
