Prayut rides big bike wearing cap – thaipbs.or.th, March 3, 2015
…Without telling anyone, he switched on the engine, pressed the horn and shouted jokingly for everybody surrounding him to keep off, or he would ram at them.
He then rode off without wearing a helmet except a red cap, forcing his body guards, media members to run after.
Gen Prayuth circled around the compound of the Government House for a few minutes and retuned to the booth, smilingly said “the bike is powerful”…
Seem to me that Big Too just follow the way the late Uncle Chatchai Chunhawan, an old cavalryman who loves to ride a Harley Davidson chopper.
