Club, Endurance and Isle of Man racer, been riding bikes since 1970 something, got the bug sitting on the back of my dad’s 400 Four. First ride was an Italjet followed by RM80 and YZ125 dirt bikes, current bikes range from agricultural to exotic. Writing about bikes for four years.
Bell Moto Flex - 9
I have been testing the Moto – 9 Flex for 12 months. Like the Sidi Extreme SRS boots the helmet has seen some action and has held up well.
The carbon-fibre visible on the Moto-9 Flex is a good indication that this is Bell’s top-of-the-range off-road helmet, and while it lends additional claimed protection, I don’t think the awesome graphics do much to make it safer.
The words ‘carbon’ and ‘fibre’ are usually linked to a drop in weight, but the Moto-9 Flex weighs the same as the Moto-9 it replaces. The reason it weighs the same is down to the new technology:
This helmet features Bell’s ‘Flex’ technology – a protection system that’s made up of a three-layer impact liner designed to manage energy transfer so impact forces are limited from reaching your head.
The core protection is made up using three layers designed to absorb impacts in different ways according to speed and features a mix of low-density polymer (called Expanded Polyolefin), expandable polypropylene and expanded polystyrene.
Alongside the layered structure is a rotational energy management system, intended to protect the brain from becoming injured from knocking against the inside of the skull, so when you take an impact in this helmet, there is a subtle movement between the inner and other layers which is designed to dissipate energy from an impact. It’s technology is now available in Bell’s road Star helmet range.
So while all that stuff is nice to have, the big question is whether it’s comfortable and thanks to the cheek pads sitting against my face in just the right place, it is.
The layered construction has another advantage it sets the helmet up nicely for an adaptive fit. When you pull the helmet on the segmented construction conforms to the shape of your head making the helmet very comfortable.
There’s more cleverness with the cheek pads thanks to the ‘eject system’, which will allow a medical team to gently and safely remove the helmet after you are injured; because the pads are held in with magnets, they can be removed prior to the shell being taken off, so reducing the risk of neck injury.
I always get hot and sweaty riding off-road and having well ventilated helmet is a great advantage. This lid features 18 vents in total and they work to create the kind of airflow I need to cool my sweaty face down. The layered internal system also helps with airflow because the air is able to move between the layers to contribute to the cooling effect.
The removable interior is made of X-static XT2 fibre, which is claimed to inhibit bacterial growth so it means the interior should prevent bad smells.
The Moto-9 Flex has an angular aggressive profile, which isn't too surprising considering the development. It’s comfortable at speed and thanks to the way the air flows over the shell, I didn’t feel the drag pulling my head back as much as I have experienced on other MX/enduro helmets. It was refreshingly free from buffeting as well.
Goggles sit well and fit easily in the helmet.
Fastening is taken care of with a D-ring fastener and the excess strap secures with a nice magnetic tab. The sun peak has is easy to flip up and down with fasteners that feel good quality.
Goggles fit and sit well in the helmet.
The Moto-9 Flex is expensive compared to other high-end MX helmets, and it’s more expensive than the model it replaces, although for that extra outlay you get a new safety system. The helmet comes with a stylish helmet bag and the fact it comes with a five-year warranty should mean that if anything goes wrong with it, Bell should sort it out.
Big thanks to the Mick Extance Experience for letting me come along to their ace off-road centre in Wales.
