Born from Bell's extensive and legendary experience, the Bell MX-9 Helmet blends the best of their dirt and street knowledge into a feature packed middleweight ADV helmet. Equally at home on the street as it is in the dirt, the MX-9 panders to those riders who are out there pushing boundaries and not stopping when the road ends and the trail begins.
The lightweight polycarbonate shell comes in three different sizes, mitigating bulk and providing a more comfortable fit. Bell's velocity-flow ventilation system keeps air flowing, forcing fresh air in and hot moist air out, while the removable and washable liner and cheek pads ensures you can keep sweat and bacteria build up at bay.
The MX-9 ADV helmet can also transform into a more streetable helmet by removing the peak visor. Included side pods replace the visor where it mounts to the helmet, giving you sleek top-gun styling. When you hit the dirt and need the added protection of a pair of goggles, simply flip up the shield and throw 'em on. The MX-9 is designed to work with any dirt goggle out there.
Truly a go-anywhere, do-anything helmet, the Bell MX-9 Adventure helmet fills a much needed gap in the market and is perfect for pros and beginners alike.

Measuring the head is only a starting point for the entire sizing procedure. Due to varying shapes, heads that are apparently the same size when measured by a tape may not necessarily fit the same size helmet. A small metal tape measure or a cloth tape may be used to make your initial measurement. You can also use a string, which can then be laid against a measuring tape.
Measure the circumference of the head at a point approximately one inch above the eyebrows in front, and at a point in the back of the head that results in the largest possible measurement. Take several measurements. The largest measurement is the one you want to use.
