In my last quick trip to Madrid I went to make a visit to Adolfo Calles, from Bonneville Motorworks. One of the most famous stores & workshops in Spain, who works and overcomes
through the years, since 1995 more or less. He is a true enthusiast of motorcycles and sick of speed.
They build radical racing bikes and clean custom motorcycles like "Cashmir"
with an S&S early Shovel engine, Roland Sands wheels, a modified "Chica" frame, painted by Bertrand Dubet in France... among numerous details.
They also have a great selection of helmets and cool stuff. So when you go to Madrid not hesitate to go Bonneville.
Thanks for your time, mate!!
