Triumph Trident 660 Motorcycle - Street (2021-2026)
The Triumph Trident 660, launched in 2021, is an accessible middleweight roadster powered by a liquid-cooled, DOHC, 660cc inline-triple engine. Initially, from 2021 to 2024, this engine produced 80 horsepower and 64 Nm of torque, with 90% of peak torque available from 3,600 rpm. These early models featured standard ABS, switchable traction control, two riding modes, and a TFT display. Significant updates arrived in 2025 and 2026. The 2025 model year introduced major technological enhancements, including Optimized Cornering ABS and Traction Control with a six-axis IMU, Triumph Shift Assist (quickshifter), cruise control, and a new Sport riding mode. The suspension was also upgraded with Showa SFF-BF forks. For 2026, the 660cc engine received a performance boost, increasing power to 94-95 horsepower and 68 Nm of torque, with a raised redline. This year also brought new bodywork, a redesigned fuel tank, and a new split seat. Throughout its production from 2021 to 2026, the Trident 660 has primarily offered various color schemes, alongside special editions like the 2025 Triple Tribute, which included a quickshifter and specific graphics.
