    PROJECT DEVELOPMENT

    • The KB4 targets are simply to achieve : easy ride, torquey and lightweight bike.
    • Thinking about a friendly, new category bike – what should we do?
    • Engine, Wheels, Seat, Controls.
    • The most compact connection between the rider and the ground.
    • The most lightweight connection between the vehicle and the rider.
    • The concept for the KB4 uses a machined light alloy swing arm, directly connected to the most friendly engine on the market, to make an easy feeling between the rider and the front and rear wheels.
    • It also uses solid carbon fiber bodywork for the lightest support for the rider,it must be “EXCITING to see” and “AMUSING to ride”.
    • When you go through the corners – you get excited by the unmatched handling performance!
    • If you twist the throttle you feel the smooth engine response, strong and fluid!
    • Our dream – give the customer EXCITEMENT! – both in the way that the motorcycle looks and the way that it rides!!
