Model Year 2019
Ventilation ★★★
MTB Helmet Type Trail / Enduro
Weight 361 - 365 grams


As mountain biker you know like none other how demanding your sport is. To meet those demands, Bell developed the 4Forty MIPS. The 4Forty is a comfortable helmet with a snug fit. The 15 vents provide an air current and the Sweat-Guide padding drains moisture. In addition, the helmet’s fit is easy to adjust thanks to the Float-Fit closure. This Float-Fit closure is integrated into the MIPS crash protection. MIPS is a system built into the helmet’s cage and reduces the impact on the head in a crash significantly. This decreases the chance of head injuries in a crash.

Looking for a helmet that’s comfortable, protecting and affordable? Then look no further than the Bell 4Forty MIPS!

Good value entry to MIPS

Nice helmet. It's a bit tricky to get the fit perfect so that the helmet sits in the same position whilst riding. Nice and comfortable of medium weight. The visor can be raised or lowered but essentially only has the the extreme positions. It's also easy for the visor to look crooked. Probably not the coolest for ventilation but as I swapped to eMTB at the same time it's much less of an issue and pushing the peak up helps direct more air in. Like the availability of replacement padding although couldn't find the correct matching colour but that's minor.

Excellent fit, very comfortable and provide good protection.

Provides great protection at a reasonable price. Very comfortable to wear for long rides. Plenty of fit adjustment to get it nice and secure. Great helmet.
