Yamaha N-max 155

"The reliable, underrated urban commuter that rewards a careful used buyer."

The N-Max 155 is probably the smartest used scooter buy under four grand right now. Yamaha got the fundamentals right — the VVA-equipped 155cc single pulls surprisingly hard once it hits 6,000rpm, the traction control actually works in the wet, and that keyless ignition system holds up remarkably well on older examples. Suspension is genuinely planted for a scooter this size, and the underseat storage swallows a full-face helmet without drama. That said, buy one and you're inheriting someone else's maintenance sins. Check the CVT belt religiously — most previous owners ignored the 12,000-mile service interval. Front brake fade is real if pads haven't been touched. The stock screen is basically decorative above 55mph, and you'll want to budget for an aftermarket unit immediately. Also inspect the ABS sensor wiring on anything pre-2020; it chafes against the frame and throws phantom fault codes. Overall though, this is a genuinely accomplished machine that ages well when maintained properly. Parts availability is solid, Yamaha dealers know them, and resale holds better than most competitors.
