The SL350 was the off-road styled member of Honda's 350 twin family, sharing the CB350's 326 cc SOHC twin but with high-level exhausts, a 19-inch front wheel and trail-oriented tyres. Rarely seen in Europe, it sold well in the USA, where early-1970s revisions to valve timing, fork damping and seat comfort gave it more low-down pull and better manners.
