Bell SX-1 Reactor Helmet (2XL Only) 4.3 5 3 3
Solid entry level helmet. Worth buying for the casual rider. I'm just getting into off-road riding and this helmet worked great for me. It looks great, is much lighter than my Bell Star street helmet, and has already saved my butt in a few crashes! Definitely a good entry level purchase. However, some downsides to note are the lack of substantial ventilation, spots for headset earpieces, and fully removable padding inside (for cleaning.) June 6, 2015
Bell quality Fit is about one size small get next size larger. Great looks and is light,no neck pain. June 1, 2015
Decent helmet for the price I haven't used the helmet while riding yet. Bought it for the price and I like the look of it. Feels fairly light. Size does seem to run on the small side. April 6, 2015
