The FX 650 Vigor was the reworked version of Honda's Spanish-built SLR 650 road-going single, launched at the end of 1998. It kept the air-cooled 644 cc four-valve engine and chassis but gained a rev counter, a small cockpit fairing, a new seat with side and tail panels, and an XR-style tank. It is a characterful, torquey big single for back roads and town rather than a fast bike.
