This plan for a smaller adventure bike was recently uploaded on MoreBikes and yes it could be the plans for the Africa Twin Sport Concept.
From the drawing, you can see a new two part switch located on the left handlebar. Maybe this extra module will be used for ride mode selection. The luggage rack and dual passenger seat certainly looks similar to the full sized AT too. It also looked to have the proportions of a mid to large sized bike, something along the lines of the Honda NX650 Dominator but with the styling of the Africa Twin.
The new Africa Twin Sport Concept is set to be unveiled at the upcoming 2016 Osaka Motorcycle show this weekend along with a few other models. We don’t know much about it but Honda says it will take the CRF1000L Africa Twin base model to a whole new level.
