In most parts DOT branded tires are a requirement for road certification. 250cc is almost a defacto standard for off-road, they offer an excellent balance of power to weight and suited to entry level off road competition. For experienced riders and road riding beyond city and rural roads, large displacement singles are far better suited. The current model 450cc singles, given tire, gearing and suspension modifications, even make an excellent platform for GP style road racing. see: http://www.450gp.com/EN/
