hey guys i just brought a brand new 2011 yz450f. i havent had a problem with it until today. i was keen to go for a ride so i made sure i had fuel checked my oil and my radiator fluid and all was good. i started my bike to let it warm up then went and put my helmet on and came back 2 mins later and there was radiator fluid, steam and smoke coming out of the radiator overflow. i turned off my bike straight away let it cool down and checked the radiator and it was dry as a bone. what can cause this 2 happen? this is a brand new bike with only 2 hours and 29 minutes on it

Dont even touch it mate, bring it straight back to the dealer for them to sort it out

yeh i am i rung them straight away and im taking it there first thing monday. just want to know if anyone knows what would cause this?
