That cd250 looks fantastic! The FI on the TU 250 is a quality setup and not any kind of nightmare, its easy to trouble shoot in the event you would ever have a problem with it, which is VERY unlikely. If you are not mentaly challenged, you can test every sensor, and the system even has fault codes for any bad part. It also does not seem to be set lean like most carb bikes as its got a cat in the exhaust and air injection, which allows Suzuki to set the mixture right without failing EPA testing. And don't compare a 125 2 stroke to a 150 4 stroke, the 2 stroke can make close to 20 hp, the 150cc 4 stroke single is going to make 12. If it does over 55 mph its in free fall off a cliff. Also, a good used low mile TU, with say under 1000 miles on it goes for UNDER $3000.00 and they do not even break in and run their best till about 4000 miles. A more trouble free bike you will not find, and I expect mine to go over 80,000 miles without any issues. I could see a smaller bike like the SYM or Cleveland Cycle Works bikes as a vintage dual sport kind of thing, the TU sucks big time in the dirt. And there ARE old SL125's for sale around here, I am tempted as they look so nice, but 125cc of 4 stroke power just might not be enough to have any fun on. A late model SL350 would be the ticket for me.
