We took a short test ride on a new FLRT with the M8 motor.
First impression is that it'll run out from under you but that is mostly due to (too?) quick throttle response. Rolling on once moving is faster but not much. Can't expect miracles from a 10% boost. It felt like it rode a bit softer and steered a tad easier but that could be just handlebar position and tires. New motor is definitely smoother and tranny clunks less thanks to clutch releasing better. Very nice trike but not sure it's $10,000 better than my 2015. Maybe later .....
