Don, I rode a GS750 Suzuki for 7 0r 8 years. The wife and I put 90,000 miles on that bike without any major trouble. I had to put an altenator in wasn't very much money and took me a little over 1 hour to do. Other than that the rest was just taking care of the bike. Oil, filters, chain lube and chain, did have to put rear sprocket on after about 70,000 miles. we rode the heck out of it and I loved the bike. Really no difference between the gs650 and the 750. If the price is right I don't think he can go wrong for his first bike.
