it depends if the other bikes your riding with are big bikes that flick up lots of roost(rocks ,sticks ,dirt) at you ,if they do then yes get armour it sure as hell beats a rock blown to the chest ,they also come in handy if you tend to wind your self alot like by going over the bars or what ever.For goggles i highly recomend utopia too dirty goggles ($79) or oakley o frames ($49) it depends if you use tear off's or not and for gloves you cant go past the fox dirt paws ($29) ive had mine for 2 years and ive put them through hell and they still havent ripped ,and for a helmet there's no better buy than the one industries kombat ($269) its the best helmet and looks like u paid 900 for it especially when its the monster energy edition!!!
