Pattaya Big Bike Rental?

So i've lived in Pattaya for almost six months and i'm looking to rent a big bike, 1000cc+.

Where are the best places to rent, to avoid the ever present scams etc.? Do any of the have any experience renting big bikes? And are there any certain things i should/shouldn't do and should look out for? Minus the obvious, like crashing

I am below 20 yo but have a Thai bike license and experience on big bikes, just want to explore some options and try something new, different.

Thanks in advance
