On the new S4rs and i think the S2r 1000ds you can see a knock sensor thing in the side of the cat bulge on the left hand side. I guess the reason for these is emssions etc but will it help the bike to run better generally?
As i know when my dealer has been tweaking my s4r they stick a sensor in the little bung in the down pipes to check Co2 levels. Guess this will be like an onboard one I heard Bmw bikes and most cars have had them for ages can compensate for all sorts like lower ocatane fuel etc.
Anyone know mucho about them
