Authentic Kart Replica Kyosho 31315T1 BIREL R31-SE

The Kyosho 31315T1 recreates the compact profile and steering focus of a kart in a 1/5 scale Readyset. It aims to reproduce the essential driving dynamics of the R31-SE while remaining accessible to hobbyists stepping up from standard on-road models.

GZ15 Engine Layout and Dynamics

By placing the GZ15 engine beside the cockpit area, the model mirrors full-size kart balance and a low center of gravity. This layout supports crisp responses to steering inputs and steady behaviour through quick direction changes.

Kart-Style Steering Geometry and Brake System

Trail knuckles, a rigid non-differential rear axle and a straight muffler are included to match kart steering and scale appearance. The disk brake applies stopping force at the rear axle to provide consistent braking performance.
