Head off-road: Best motocross and dirtbike helmets

Updated: 24 September 2024

The main difference between road and motocross and dirtbike helmets is the provision of a visor. Most MX helmets are designed to be used with goggles, as these can offer a better view as well as maximising airflow to the rider’s head in what is likely to be a strenuous and demanding riding environment.

They will also have a peak to keep the sun, rain and debris from other riders away from the goggles and the chin bar will be extended, again to maximise airflow for cooling and for breathing by the rider.

Ideally you should be looking for helmets approved to the latest ECE approval, as this will certainly be necessary for use on the road. However, even if using off-road, then it establishes that the helmet meets that safety standard.

If you intend to use it in proper racing, it will also need to be ACU (Auto Cycle Union, the governing body of UK motorcycle racing) approved as well, to a minimum of Silver standard for off-road racing (Gold is for road racing on sealed surfaces).

Another technology adopted by professional MX riders is the Mips slip-plane, a plastic layer between the inner and outer sections of the helmet that allows the helmet to rotate in relation to the head in a glancing impact. This helps to dissipate energy and reduce rotational brain injuries in riders.

Here is a selection of motocross and dirtbike helmets to keep you protected.

O'Neal is another brand with an enviable reputation in the off-road and motocross worlds, and with good reason. This helmet features a shell formed in ABS plastic and comes up relatively light - a quoted weight of 1450g for a Medium is certainly not heavy.

If you want some retro styling to your off-road helmet, then this one from Dexter will do just that. It will conjure images of desert racers and riders from California in the 1960s and 70s - On Any Sunday style. However retro the resign though, the technology is thoroughly modern, with a fibreglass shell for strength and low weight - just 1250g.

The interior is both hypoallergenic and removeable for washing and features faux leather detailing to complete the retro look. It comes with a tinted peak and goggles with both tinted and clear lenses and has multiple vents for cooling.

Viper RSX121

I've used various bits of kit from budget manufacturer Viper in the past and have always been impressed by the quality and value for money, so there is no reason why this motocross helmet should be any different.

It uses a thermo-resin plastic shell with a removable and washable lining and a double D-ring strap for the correct fit every time. It’s not the lightest – 1500g quoted weight – but it has an adjustable peak and is approved for road use in the UK and Europe and is also ACU approved.
