Yamaha Xsr 155

"The sharpest retro-styled commuter under $4,000, bought carefully."

The XSR155 is genuinely one of the smartest small bikes you can buy used right now. Yamaha's R15 engine underneath that retro skin means you're getting proven, rev-happy reliability that'll run forever if the previous owner wasn't a complete hooligan. Check service records obsessively — these attract young riders who thrash them hard then skip oil changes. The VVA variable valve system makes a real difference above 7,500rpm, giving it a noticeable surge that keeps commuting actually fun. Used prices are holding stubbornly firm because everyone knows what they're getting. Don't pay anywhere near new money for anything over 15,000km. Inspect the exhaust headers for bluing and stress cracks — spirited owners push these hard. Fairings are expensive to replace and love getting dropped in parking lots, so check every panel edge carefully. Forks feel slightly underdamped with a pillion, and that narrow seat will remind you of its budget origins on anything over an hour's ride.
