Overview
The 2026 Triumph Trident 660 is a naked motorcycle from a model family produced from 2021 to 2026. Its naturally aspirated, liquid-cooled 660 cm³ inline three-cylinder engine makes 93 hp (70 kW) and 68 Nm at 8,250 rpm; wet weight is 195 kg.
The 810 mm seat height may make it harder for shorter riders to put both feet down, while the 195 kg wet weight is something to manage when maneuvering at low speed. Torque peaks at 8,250 rpm, and the Showa rear shock lets riders adjust preload and rebound to suit their load and road conditions. Fuel consumption is 4.9 L/100 km, with a calculated full-tank range of about 286 km from the 14 L tank.

Pros and cons
Advantages
Adjustable rear suspension
Preload and rebound adjustment on the Showa rear shock let riders tailor its response to their load and preferred setup.
Slip-and-assist clutch
The clutch’s assist function reduces lever effort, while its slipper function helps calm the rear wheel during hard downshifts.
Things to consider
Chain final drive
The chain needs periodic cleaning, lubrication, and adjustment.
Seat height
At 810 mm, the seat may make it harder for shorter riders to get both feet down at stops.
