Release and generation details
Release and generation details	Announced 22 January 2026, with maker-planned dealer availability in March 2026. Exact updated 95 PS models are now in stock at UK dealers; an independently confirmed first retail month was not found. This is the revised 2026 generation, distinct from the earlier 81 PS Trident 660	Substantive 2024 redesign announced on 1 November 2023, documented in Yamaha's retrospective 2024 exhibition and retained in the current UK range. Japan's 14 March announcement scheduled sale for 17 April 2024; this does not establish the earliest worldwide retail day, so year precision is retained. Main specifications and Ice Storm images use the current UK 2025 model-year listing of this generation. Y-AMT is a later transmission option, not a separate paint-year model. The available 2024-named UK fact sheet has been updated to mention Y-AMT weight; it is not treated as an untouched launch sheet.
