1975 Yamaha RD125 twostroke

The RD125 was Yamaha's scrappy two-stroke answer to European dominance in the '70s—peppy, bulletproof, and now genuinely rare with a freshly rebuilt engine at $3,300. If you understand that "slow bike fast" beats a garage full of complicated modern machines, this is the kind of genuine vintage commuter that actually gets ridden instead of posing.
