Slow puncture rear tyre GPX Drone

[Hmunker]

So I have a slow puncture that is needing air more often.Normally I would just go out and get a new tyre and been quoted 1000 baht.But in few weeks probably going home for a few months so was going to wait till I come back but need to take action now.I see on the tyre it says tubeless. I know on bicycles inner tubes can be fitted but is that done on motorbikes?. If the inner tube idea not so good and too much messing around I will just go ahead and replace.Any suggestions 

Thanks

motorbikes do come with inner tubes so are available, can also buy cheaper tyres
