Long term visa

My girlfriend is balinese and I am settling in Bali for one year initially to see what it is like...I believe I can get a 60 day visa upon arrival ...but how can I get a long term visa ? say 1 year and permission to buy scooter etc...Kitas Visa ?

If you're serious in your relationship, marriage sees a pretty much guaranteed KITAS, convertible to a 5 year KITAP after two years of marriage.

Thanks
