Updated Suspension and Brakes
The redesigned front brake system features a new caliper and floating piston for improved stopping power. The lean bars have been upgraded with a bearing mount for better traction on hard surfaces. The Promoto platform also includes a fluid-filled friction chamber between the upper and lower head tube bearings, utilizing 500,000cSt fluid for enhanced steering stability and to control potential "head shake."
Three Driving Modes
The included DX3PM transmitter offers three distinct driving modes:
-
Dirt Mode – Allows aggressive riding with controlled wheelies.
-
Street Mode – Limits front-end lift for maximum acceleration on pavement.
-
Wheelie Control Mode – Lets you ride wheelies as long as you want with electronic assistance.
High-Performance Electronics
For a true gyroscopic feel, the Promoto-SM features a high-RPM flywheel motor mounted low in the chassis, spinning at over 22,000 RPM. The driving force comes from a Spektrum Firma 3652 3800kV 4-Pole Brushless Motor, powered by a Spektrum Firma 85A Brushless Smart Motorcycle ESC. Just drop in your battery and braap it up!
