For me, the chance to ride a prototype street version at Misano was a trip down memory lane. The newest version is better than the original Tesi 1D, mainly because the air/oil-cooled desmo engine is the right tool for the job, and the Double System air shocks front and rear deliver more compliance and control than the 1D's conventional Oehlins hardware. Free of the weight and bulk of the previous eight-valve desmo V-twin, the new-generation 2D is smaller, shorter, lighter and refreshingly agile. Propelling its 339 pounds (dry) with 77 rear-wheel horsepower, the Bimota accelerates with enthusiasm up to 9000 rpm with very little vibration. After remembering you can trail-brake a Tesi hard into a turn without losing the front end, I started enjoying myself more and more until I ran out of petrol.
