Bike is a 02 V92TC Deluxe. 40k on the odometer. Bought 4 months ago from family of deceased friend. Tread is good- front and back. Mfg date on front is 0307 (3rd week of 07). Rear is 2515 (25th week of 15). Bike stored inside. Left sitting for 1.5 years after guy died. No dry rot. Wheels have spokes, so tube is involved. So, how old is too old?
