protective gear wise i would go for full motocross gear, as it allows more movement and stretch than your normal clothes. a full armour top aswell as a helmet should be fine for what you will be doing. also proper boots are a must. you will kill your ankles and feet without them. you can also get all sorts of neck braces and other braces but they arnt needed unless your racing as they are very expensive. I've had bikes for years mate....although i sold my last bike 2 years ago and massively regretted it so i went and bought the 450. I've always been very confident on a bike though, took me no time to get it sussed again lol
