Given that usable torque is available over a huge speed range, I'm still struggling to understand the benefits of a 4-speed gearbox. I would prefer to shed some weight instead. More power? I only ride on the green map anyway, and I doubt there are many people using the red at all. Personally, coming from the background of owning a '21 race and riding easy route, my wishlist would be:
Less weight
No need for a clutch, but keep the rest of the Race powertrain
More ground clearance
A way of getting a super-smooth low-power mode for tight slippery turns but also a sharp snap off the bottom to lift the front over obstacles (maybe EM-connect does that)
Better paint quality
Better fit of plastics
Better prop-stand
Lower price!
