Motoism’s Premiere: Honda GL500-JPN


When we visited the Custombike Show in Bad Salzuflen in December last year –  a show that is considered being the largest of its kind in Europe – we already got a first glimpse at Motoism’s nearly-finished first bike, a beautifully customised GL500 that had been customised to an outstanding level of detail. By that time, we were fully sold on the two brother’s work. I mean, look at that custom headlight, the upside-down fork, and that awesome rear in combination with those Conti tyres! The two brothers wanted to create an urban and sporty rider with a reminiscence to the 80s. Isn’t it just perfect?
