I will come to Bangkok (from Beijing) round bout Feb 6 for a week.... looking to check out some bars, shops and events that cater to motorcycle riders of big engine bikes. Any info is apreciated.

Shops all over Bangkok. I highly recommend "Bikers" for any CNC parts like handle bars, clutches, etc.. They offer awesome quality products....
