do not, never ever go to Kapar motor and Berjaya somthing motor.. these two shops are not reliable at all. And both shop are in kapar.
u made a good choice to start on 250. Next upgrade, straight on to full liter bike. No regret.

u can buy bike from them, pay cash, take ur bike and never come back again.

if you want to service your bike, go to your preferable workshop, or u can go to the most favorable blade workshop, in subang bestari.. Majority the Bladers love to hang out at this shop. Very cheap, and expert too. (ex-Naza pomen)

their loan interest is high...but if that its ok for you, then go ahead.

just make sure their pomen never touch your bike. They will bullshit you with lifetime warranty la, free labour la watsoever.
If one day ur bike broke down (touchwood), just sent it to Naza Centre.. somemore every Naza bike have official warranty from Naza itself, no matter which shop you bought it from.
