i cant seem to find the vin on my bike, i want to title it and have the original bill of sale from the previous owner and the engine and model numbers match but i dont kno the location of the vin or i guess it would be the frame serial number

 

it should be on the lower frame near the fenders kinda.. mina also says it on the plastic nose deal on front of atv by handle bars

 

i checked the square down tube like others have said but still do not see anything, i have the model number under the seat but think i need the serial number for a title
