2026 Triumph Trident 660 vs. the middleweight nakeds

For 2026 the Trident's triple gained 17% more power — now 94 hp, matching the four-cylinder Honda and beating the twins — with ride-by-wire modes and a TFT, at a competitive price. Here's the honest look against the mainstream middleweights.

Why buy the Trident 660 from Empire

A characterful British triple that splits the middleweight difference — now with class-leading-tier power.

  • ✓
    The only triple in the class. Three cylinders give it the smooth top-end and midrange character the parallel-twins can't match — and it's not a peaky four, either.
  • ✓
    17% more power for 2026. Now 94 hp — level with the four-cylinder CB650R and well ahead of the MT-07 (72) and GSX-8S (82).
  • ✓
    Grown-up electronics. Ride-by-wire with rider modes, switchable traction control and a color TFT — genuinely premium at this price.
  • ●
    Straight talk. The MT-07 and Z650 cost less and are a touch lighter; the GSX-8S makes more torque (57 lb-ft) with a big TFT for less money; the CB650R matches the power with inline-four smoothness. The Trident's edge is triple character and Triumph finish.
A great real-road bike for the Inland Northwest. Enough torque and smoothness for a run down I-90 or the canyons toward Coeur d'Alene, light and friendly around Spokane Valley, and a fantastic step-up bike as skills grow.

And the price is the price. Our advertised number already includes freight, setup and our documentation fee — only sales tax and title/registration are added.
