gear helmet around 250 quid for a half descent one , boots with vertibrae to stop you bending you foot back if you have an accident around 120 quid £ but there worth it ) , gloves with kevlar nuckle protectors around 30 quid (again worth it ) , jacket and trousers - vary on style and material cheapest set ive seen is 120 but do go over 1000 quid also highly recommend a spine protector that velcro's to your body under your jacket .
