Kawasaki H2 with a modified Vanhool exhaust cannot be ridden on the road. Whether it's a car or a motorcycle, any modification is illegal. Permitted modifications include: small and micro passenger cars installing front and rear anti-collision devices; cargo motor vehicles adding windshields, water tanks, toolboxes, spare tire racks, etc.; interior decorations of motor vehicles can also be enhanced. Prohibited modifications include: altering tires and rims, adding spoilers, changing lights, modifying exhaust pipes, etc., all of which are considered illegal modifications. After such modifications, the vehicle must be restored to its original condition to pass inspection. Additionally, penalties such as fines and license suspension may be imposed.
