How Much Power Does the 2025 Triumph Daytona 660 Make?

[Admin]

Triumph has returned to the supersport segment, reviving the Daytona name. But just as we’ve seen from other manufacturers, this new middleweight sportbike is not like those of the past. Today, this segment plays in a different field. One of practicality, comfort, and performance.

The 2025 Triumph Daytona 660 is based off the Trident and Tiger Sport 660. All three models share a 660cc DOHC liquid-cooled inline-three with a 240-degree firing order. But the Daytona engine receives a ton of modifications including new pistons, larger exhaust valves, a new crankshaft, and a new cylinder head. Triumph also granted the Daytona 660 a larger airbox with three 44mm throttle bodies.

The Daytona 660′s stainless steel perimeter frame is based on the Trident but revisions have been made to the geometry for more aggressive handling. Rake and trail are down from 24.6 degrees and 4.2 inches on the Trident, to 23.8 degrees and 3.2 inches on the Daytona. Suspension components include nonadjustable Showa SFF-BP fork offering 4.3 inches of travel and Showa shock with preload adjustment providing 5.1 inches of travel. A basic electronics suit offers three ride modes (Sport, Road, and Rain) and switchable traction control. Braking is by way of dual Triumph-branded four-piston calipers with 310mm rotors up front and a single-piston caliper with 220mm rotor out back.

Before rolling onto our in-house Dynojet 250i dynamometer, the Daytona hit 444 pounds on our automotive scales. On the Cycle World dyno, the 2025 Triumph Daytona 660 produced 85.1 hp at 11,330 rpm and 44.7 lb.-ft. of torque at 8,360 rpm. For reference, the 2023 Triumph Tiger Sport 660 made 71.8 hp and 40.8 lb.-ft. of torque and the 2021 Trident 660 churned out 72.1 hp and 42.9 lb.-ft. of torque on the Cycle World dyno. As with all of Triumph’s triples, the Daytona 660′s power curve increases at a near perfect 45-degree angle and the torque curve is flat like a dinner table. In our recent middleweight sportbike comparison with the 2025 Daytona 660, In-Market Editor Bradley Adams says it best, “The engine is incredibly smooth, with a blend of torque and top-end performance.” He continues, “The billiard table-smooth torque curve and unique sound help the Daytona 660 stand out from the competition.”
