I've had my 1990 Suzuki DR350S for about 4 years now. Bought it for $800 and it looked like you'd expect for an 18 year old dirt bike with 16,000 miles. Everything scuffed up, discolored and mismatched, but a good running bike despite the looks. Kick start only, one of the most no-frills street legal bikes possible and still light enough to be good off road.
Over the years I cleaned it up, buffed out the plastics, and generally modernized it to the point there aren't many signs of it being 22 years old now with over 22k. The top end still has never been apart and it doesn't use oil. I wasn't a Suzuki guy, I just got it because it was cheap, but this thing won me over. Tops out at about 95 mph, completely thrashing it I get 45 mpg and if I baby it I can get close to 80 mpg out of it.
For long trips (over an hour straight) that narrow seat starts to get a little uncomfortable. Apparently the rambler mentality is a transferrable asset. Instead of spending $400 on a saddle seat, I got this thing called the sweet cheeks. Slide a 2 liter bottle in each side and bungee cord it down around the frame - and now the seat is 3 times as wide and a heck of a lot more comfortable. And I keep the 2 liters filled with gas, so if I run out (2 gallon tank) I have a backup plan now.
