2021 Triumph Trident 660 — Should You Buy One?

Typical asking price: $6,500–$8,500. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

A brilliant middleweight all-rounder — Triumph's characterful 660 triple, an approachable upright riding position, and genuinely premium build make the Trident one of the best value 'do-it-all' bikes going. Friendly for newer riders, satisfying for experienced ones. Reliable and well-priced. A clean Trident with records is a superb, versatile bike that punches well above its price; check consumables and for drops.
