As with so many things, the answer is "it depends". Having a bike sit unused for along period can be worse than high mileage: corrosion of metal parts, rotting of rubber, deterioration of fluids, etc. This one has accumulated 500 miles/year. Was it run frequently but only on weekends (not too bad) or did it accumulate 7,000 miles in its first decade and then sit unused for seven years (that's bad!)? If this were my problem, I'd try to find out as much about the history as possible. New tires is good, but also think about a new drive belt, oil, and strut fluid, lubing cables, swapping out bushings, etc.
Edit: I just noticed from your other post that you're in India. Just get a Royal Enfield.

I'm a chemist, so here comes the lecture:
All alcohols are not created equal. SeaFoam is mainly isopropanol (aka "rubbing alcohol"). Compared to ethanol (aka "grain alcohol") or methanol (aka "wood alcohol), isopropanol mixes more easily with gasoline and less easily with water. It acts as a "co-solvent" to drag moisture into the gas while still allowing the gas to burn, so that it won't separate out into its own (incombustible) layer. Being somewhat "water-like" it also tends to keep additives in solution so they won't precipitate out as gum and/or varnish.
As far as not wanting to add any alcohol to the gas, when you add 1 ounce of SeaFoam to a gallon of gas, the concentration is 0.7%, so it's nowhere near the 5 to 15% ethanol you see in pump gas.
I put an ounce or so in every few tankfuls on my wife's Kymco Super 8 150, and I put in a couple of ounces per 2-gal tankful every time on my Royal Enfield Bullet 500. No major problems with either one at 5,000 miles and 12,000 miles respectively.
