Phil Ang at Caloocan Sales can source just about any bike you want. Also has a showroom of imported new big bikes. Very professional outfit - just like dealing with a 1st world outfit! I bought a new Fazer 1000, VStrom 1000 and Yamaha Super Tenere 1200 from him over the years. All import duties paid on them and registered within a couple of weeks . Consequently nothing to fear if driven in Manila, unlike some grey imports here!
And getting back on topic - the 650Versys is a piece of cake to handle in traffic. You would have no problems around Dumaguete!
