Gif: there are some faster trikes around. They generally have skinny tires, 700C rear wheels, and a a more laid-back position. The ICE Sprint X comes to mind:

Also Bacchetta Carbon Trike, Greenspeed Aero, and Catrike 700. Trikes are always at a disadvantage in the speed department, due to multiple factors. If you want speed but are reluctant to chance a fall, I recommend a lowracer. Falling from 10 inches is a non-event - you may lose some skin but there's no impact damage.
