Honda Brazil's successor to the NX 350 Sahara, using a 397 cc air-cooled RFVC single related to the XR400 engine, a five-speed box and disc brakes at both ends. It was a tough, road-friendly trail bike with a roughly 300 km range, widely used in Brazil including by the army. Tighter Brazilian emissions limits ended carburetted production in 2008.
