I bought a 2006 Suzuki SV650 for $5,450, and then later gave it to my daughter who still rides it. I don't think they have done much of any servicing to the bike for the past 10 years and it still starts and runs as well as ever. A really nice little motorcycle.
When my daughter went to UCSD, I bought her a 1990 Suzuki GS500EL for $2,800 as transportation while she was going to the University. She really got a lot of use out of that little bike. She would sometimes ride it from San Diego to my home near San Francisco, leaving on a Friday afternoon, arriving here early Saturday morning and leaving on Sunday afternoon for the ride back to Southern California. At times she would have to split lanes for a hundred miles to get through LA traffic. After she graduated and moved north of Seattle, she would ride the Suzuki from her home to my home on a weekend and return nonstop, except for gas, a 900 mile ride.
When the bike had 80K miles on the clock, her husband borrowed it and forgot to check the oil level. He ran the bike out of oil and the engine froze up. He borrowed a car from some friends in Portland, took the Suzuki apart and drove back home with the parts in the trunk and back seat. After arriving home, he reassembled the bike, poured oil in the crankcase and it started right up - although it did have a knock from the bottom end. My daughter rode the knocking GS for another 6,000 miles before finally selling it to a Mexican fellow for $800 who planned to ride it back to his home in Mexico City. Now that was a tough little sucker.
