Five years ago, Bjorklund set a 1,000cc A-AG (altered frame, normally aspirated engine, pump gas) record of 166.360 mph on the Team Super Rat Ducati Monster S4RS. He didn’t begin building his next bike, the double-engine machine seen here, until 2014. “I was planning on using a single engine. Then, I thought, ‘What if I put two Ducatis together?’ I’d be going after the 2,000cc A-AG record, which would mean I wasn’t trying to beat my own 1,000 A-AG speed.” Bjorklund built a jig to bolt the 128-hp V-twins together using new frame lugs he machined to mirror factory lugs. He welded gussets to the front steer tubes and ran bolts through to center those on the frame table. Then he measured his body to determine wheelbase—11 feet.
