2017 Honda CBR1000RR and CBR1000RR SP Review

About the only exotic materials you can see in this picture of the SP are the titanium exhaust canister and magnesium crankcase cover. But the quest for weight savings go far greater. Don’t forget the titanium fuel tank (steel on the standard model), aluminum subframe (which, granted, is partially visible), hollow transmission shafts, and even thinner fairings compared to the old bike.
