I accept that, but if the guy was 66 years old, just returned to Thailand and was riding it a big bike then it wasn't a renter and he was likely a very experienced rider.
I never rode a bike until I arrived in Thailand 18 years ago and I gravitated from a click to a Neuvo to a PCX to a Forza. I feel comfortable and safe on the Forza but rarely exceed 100 kph; I usually ride at 80-100 kph, less when conditions demand it. I am 68 years old and have told myself that the moment there are any signs of my driving skills deteriorating then the bike will go.
