I never see the exact jack / motorcycle lift in Thailand, but I hear about the Risk Racing Ride on Lift, which seem to the thing that you want...
Now is Risk Racing a USA company, but they mention that Panda Rider Station in Bangkok is a dealer, so with some luck you can buy the Ride on Lift from them... The Ride on Lift costs in the USA US$ 149 (about 1520 THB without shipping).

Hello All, I was hoping someone on this forum could help me find some place in Thailand where I can buy a Motorcycle jack like (or similar) to the one in the picture that I've attached. I will be using it to do maintenance on my Kawasaki Vulcan 900 so I wanted something Good and stable. Or if someone can suggest a different type of suitable lift I could use, I would really appreciate it. Thanks in advance for your help. Cheers
