Motoism presents: the Honda GL500-JPN.

Past and present collide in this bike, which we consider a quite successful 1980s freshing up. A down-to-earth motorcycle meets uncontrived design and racetrack technology. Thereby we kept it raw and simple. In the end, it is the completion of a basis that itself was promising already. The bike’s new name is a homage to its homeland Japan. The Honda GL500-JPN was originally limited to a number of 10 pieces. Due the high amount of requests Motoism is now manufacturing 16 bikes in total.
