The 1988 Ducati 851 Superbike Tricolore still holds the claim as one of the most influential motorcycles of recent times, and not just for Ducati.
This model essentially paved the way for Ducati's future (now current) success in their family of superbikes.
A lot of this can be attributed to Italian engineer Massimo Bordi, who designed and engineered the Ducati 851. Bordi's thesis as a university student was centered around a Desmo 4-valve, and he eventually made this dream a reality. Besides being the architect of the Desmo 4-valve, Bordi is also the father of Ducati superbikes.
Two models of this motorcycle were initially available - the 851 Strada and the 851 Superbike Kit. The latter was produced to meet requirements for the World Superbike Championship.
The model in the Haas Moto Museum's Race Track is an 851 Strada. Only 311 of these were ever produced.
