My story... my AB SA quoted me 1.6k without pref number.
Since i have long off days,i go the DIY way.
1.Bought own number.(easy straight forward process.go,see at the board.pay the price-mine normal 4digits) number valid for 30days. Cost-RM210
2.Deal with motorbike shop,told them i wanted interchange without buying a motorbike.Cost about +-RM800. (this is to cover the depreciation of the bike which was registered under my name and will subsequently sold as a pre-reg unit for lesser price)
3.Went to Puspakom for interchange B2 inspection.Process took me about 3-4hrs. Cost-RM30
4.Obtained the LULUS Puspakom doc,now clear to bring the "e-daftar" registration documents of the bike,which by then kedai motor already e-register,and original vehicle reg card of your car to be interchanged. Cost - RM210
4.Voila.new reg card with your new number with a cross-reference to the old number,now at the "new bike" which will be sold as a pre-reg 0 mileage bike.
Total cost : 1.2k + some precious hours of your life.
If u don't want to do all the things i mentioned above,pay someone to do it.
I enjoyed doing mine though
