Why is there a difference in helmets for motocross and streetracing?

Question

Why cant u use a full face helmet in motocross and an offroad helmet for street racing?

Answer 1

aerodynamics for 1 reason and the mud would destroy a street helmet in minutes for another

Answer 2

you can i guess they desingh them different because a street helmet is rounded so if you fall it will spread the impact and skid  across the pavement and motocross are desinghend for rugget terrain... but i guess if it was up to me... for my life i would wear whatever helmet i could find...

Answer 3

i think that this is beacuse the halmets are for different things eg. street racing helms are for high speed impact and motocross helms are for rugged terrain hope this helps!

Answer 4

If you wear a street bike helmet to a motocross track and race......I DONT KNOW YOU!!!

dont be that guy :)
