2021 Yamaha EX Sport — Should You Buy One?

Typical asking price: $7,000–$9,500. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

The value entry into Yamaha's lineup — the EX Sport uses the reliable, naturally aspirated TR-1 engine (no supercharger to service) in a light, friendly, easy-to-tow hull that's perfect for new riders and families. It's not fast, but it's dependable and cheap to run. A low-hour, freshwater EX Sport with clean compression is one of the smartest first-ski buys; verify hours, flushing, and pump condition.
