We frothed over the DB4 back in 1999. Using a Ducati 900SS engine in an oval-section alloy tube frame, the DB4 was shorter, lighter and had racier geometry than Yamaha’s then-new R6, and its delicate steering, high-quality suspension and stability all impressed. So too did the V-twin, with Bimota’s own exhaust and carbs instead of the SS’S injection, which had a punchy midrange and great performance at realistic speeds. Standout styling, too. You could of course get the donor Ducati for several grand less than this 7000-mile bike from 2001. But it wouldn’t be a Bimota...
