The idea to turn his SR500 into a street tracker came to Italian Andrea Costantini after viewing some photos of a Kim Boyle creation. “I searched the bike spasmodically, because I loved the mechanics” he says. Luckily for Andrea his father is a mechanical engineer and has a small workshop at home with a horizontal lathe, a vertical mill and a grinding wheel. So with the help of his Dad, Andrea went about creating his dream street tracker. “I changed the stroke of the fork, creating a shorter spacer, a spacer for the brake disc which is a Ducati 996 because otherwise the caliper from a Ducati Hypermotard would have hit against the spokes of the rim. I bought the seat from Redmax Speed Shop and we made the plates to attach to the frame anchor points. I changed the bar tension and the rod brake to simplify the rear. The tank is off an old Yamaha GT80 and the footpegs were also made and designed by my father. The painting of the frame, tank and seat were all carried out on the terrace of my home in Rome”. You can check out loads more build shots of this sweet street tracker on Andrea’s Flickr page.
