sport bikes for the keys grind, but handling needs a full rework or it's dead money

Sport class, no question. The Keys highway bridges are long straights with sweeping curves. You want top speed and lean angle to shave seconds off every sale run. Cruisers look nice but you're losing $2K–$4K per hour in slower deliveries. Dirt bikes are for off-road shortcuts that might not even exist on those causeways.
But none of it matters if the handling model is copy-pasted from V. Bikes in V have that weird mid-corner wobble and zero weight transfer. You can't trail brake properly. A full physics rework is the difference between a bike being a fun alternative and a meta tool for grinding. If a sport bike can't hold a line at 120+ without twitching, I'm back in a car and my MC business profit-per-hour drops 15% minimum. Simple math.

Trailer 1 runs 1:31 with zero handling demos. (Dec 2023) Your 15% drop assumes a speed cap we don't have.
