Here we are revealing in front of you the images of 1970s racing motorcycle by Bobby Costello. Bobby is bike builder, mechanic, and fabricator specialist. He also works for Costello Fabrications, a workshop that will build anything from exhaust headers through to bike frames to furniture. He purchased this RD125 from the Barber swapmeet for 200 dollars. After getting it, he added a Yamaha 80 tank to hide the electronic component of the bike. To updated the front brake by fitting an RD350 brake drum. Small capacity engines and pizza cutter tyres added a wonderful impact of this bike.
