If no other loan, 0 loan, even 3k can already pay the bike's installment... But, better to put aside around 500 monthly for the bike's insurance later after a year...  Insurance for sure around 3k maybe for those japanese liter bike...?? Tires front and rear maybe around another 1.5 k, but maybe only last around 6months...?? 9 months only...??

So, witout loan on car, house loan etc, no need to pay house rent (live with parent lar.. Haiya...) , just to be safe, minimum around 3.5k monthly can already have those 1 liter bike at ur house porch... But, like this so not enjoy lar Bro...

Need to have very low standard of living... Can get girls with ur bike, but once want to take home, kantoi rumah kecik, kete tarak, n once masok rumah, no furnitures, duduk pn atas lantai jer nanti... N can only serve her megi.. Hehehe
