Built by Moto Honda da Amazonia in Brazil, the CB450DX (sold as the CB450N in some markets) used a 447 cc six-valve twin derived from the Superdream CB400N. It mixed hydraulic discs at both ends and a balancer shaft with conservative styling. Cheap to run and durable, it sold strongly in South America but little elsewhere, and was replaced by the CB500 twin in 1994.
