The downloadable owner’s manual from the Ducati web site lists a Yuasa YT7-BS which is an AGM not Lithium chemistry. Not sure if there is a difference between the base, S and Corse models. Andy
Maybe it’s just like the 959 (std) with normal and the 959 Corse which has a lithium as a little extra weight saving. Pretty sure it’s safe to use either as long as you use the correct charger...
