These upgrades are intended exclusively for use on private, closed-off property or in racing. A higher top speed can mean that the vehicle no longer complies with road traffic regulations (e.g. German StVO/eKFV) and that its type approval and insurance cover become void. Warranty and guarantee claims may lapse. You are responsible for lawful use. Wear suitable protective gear at higher speeds. Digital license codes cannot be exchanged.
