The Kayo K4 is an awesome midlevel dirt bike for all types of riders. The heart of this bike is a very reliable 250 cc air-cooled 4-stroke engine with an electric starter! This smooth engine has a 5-speed transmission to get the optimal power and torque from the engine. We design the frame to be strong yet light and we gave it inverted forks, a stable rear shock and disc brakes front and rear! The K4 has a front headlight and rear taillight.
