After it first debuted in Indonesia last October, the Honda SFA concept motorcycle seems to be getting serious, as Honda will be showing the up-market bike at this weekend’s Osaka Motorcycle Show and next weekend’s Tokyo Motorcycle Show.

While Honda only mentions that the SFA concept is a “street-fighter style light-weight motorcycle with a single cylinder engine mounted on a trellis frame,” sources in Indonesia say the fetching small-displacement machine is built around the 150cc CB150R for that market.
