About the RTR Promoto-SM
Updated Suspension and Brakes
The front brake has received major updates with a redesigned caliper and floating piston to apply pressure to a larger surface area. The lean bars have also been updated and are mounted on a bearing allowing for better traction on hard surfaces. The Promoto platform is a fluid-filled friction chamber between the upper and lower head tube bearings. The chamber is filled with heavy 500,000cSt which dampens the servo saver well and helps to control any possible "head shake.”
Three Driving Modes
The included DX3PM transmitter comes from the factory with three distinct modes. Using the toggle on the side of the transmitter, you can change between Dirt Mode, Street Mode, and Wheelie Control. Dirt Mode gives the bike enough power to rip around and ride the back tire without "Wheelie-Overs". Street Mode senses when the bike starts to pitch up and clips the throttle quickly ensuring maximum acceleration. Wheelie Control Mode lets you Braap it up by keeping the front tire off the ground for as long as you want.
Electronics
To give the bike a real gyroscopic feel, a motor is placed at the bottom of the chassis spinning a flywheel at over 22,000 RPM. The driving motor is a Spektrum Firma 3652 3800kV 4-Pole Brushless Motor powered by a Spektrum Firma 85A Brushless Smart Motorcycle ESC. Slap your battery in this Supermoto and get out and braap it up!
