At 810mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with both feet flat on the 2025 Triumph Daytona 660, with a cramped knee angle of around 70 degrees and a forward-leaning riding position.

Assumes about 30mm of suspension sag once seated. This is an approximation from category-typical geometry, not a measurement of this bike or of you - sit on one before you buy.
