The 160hp number is probably at the crankshaft. That is the typical way factories give their HP numbers. It makes for better advertisements. Figure approximately 10 to 15% loss from the crank to the rear wheel. That would put the Duc at about 144 to 136hp at the rear wheel. So this one is putting 139 on pump gas, not bad at all. Watch how the hp numbers vary, as the bike gets out and about with the various media sources.
