Taycon got few. Paya Terubong, Farlim got 2, Bayan Baru, Relau...
Racingmate also deals tyres.

What bike are you after? New or used?

I don't know all of them. I've been to Masjid Negeri, Bayan Baru, and Paya Terubong one. Not the Farlim or Relau one. Generally, to me and some of my friends, they are good. Test bikes and ECU check no problem. Some other frens do tell me they are occasionally cold, means don't layan or let you test ride. I think it depends on the timing and workload.

I'd say find the one closest to your home or office, get to know their foreman and the quality of their work.

Thank you for your feedback. I am looking at Z650 specifically because of it low seat height. I am only 163 so low seat height is important to me 

Cz I don't have much experience with taller bike, even during B Full training I used Virago instead of ER6N.
Its is mostly mental I think, so definitely I need to overcome this. That's why I am looking for low seat height bike so I can get used to it~
