Should I pay more downpayment or use the money as a cash advance in monthly?

Hey guys. We’re planning on buying a motorcycle (common transportation mode where I live) and I’m wondering, if my current money is $1000 dollars, should I use all of that as down payment or should I pay the normal down payment (around $250) and use the $750 remaining as an advanced payment for the monthly? (Assuming buying a second hand/lower priced motorcycle is out of the question)
