Triumph
Trident 660
The Trident 660 transfers Triumph's inline-triple character — the same architecture as the Street Triple — into an accessible 417-lb package at $9,395 new, $6,500–$8,500 used. The low-rev torque curve and 31.9-inch seat make it the most practical way into Triumph's engine lineup without stepping up to a full middleweight.
