Powertrain updates
Improved performance for 2026 Triumph Trident 660 and Tiger Sport 660 comes from some major tweaks to the engine hardware.

These work to improve combustion and power delivery. To handle the increased performance, the 2026 Trident 660 and Tiger Sport 660 use more robust cooling systems.

Exhaust setup has been updated with a new 3-into-1 header design. The bike has an updated catalytic converter and an underbelly exhaust. Changes have also been introduced to the 6-speed gearbox, including revised gear ratios and final drive. There’s a recalibrated Triumph Shift Assist and a new slip and assist clutch.
