Blue mini bike has a big block Tecumseh h50 motor runs and rides newer build and paint, and has the ability to have handle bar killswitch hooked up. I personally didn't hook up wires being the motor has it's own. Seat has seen better days.
The red one has a 3hp briggs and stratton engine also fresh build along with paint and new tires rims and seat are original to the 70s eltigre frame runs and rides older engine around same period as frame seat has small tear as you can see in picture. Has foot brake.
