The 2026 Trident 660 is a performance-focused update with roughly 14 PS more power, a higher redline, new throttle bodies, airbox, cylinder head and gearbox ratios. It also gets wider bars, a revised frame, new bodywork with a wider tank, and a rebound-adjustable rear shock. It stays A2-compatible via a restrictor kit in Europe.
