Question: LT, I'm nervous about using aftermarket belts on my Ducati. Would you recommend against their use.
Answer: I've been using the Bucci brand aftermarket belts on my Ducs for years, and have never heard of a single belt failure when replaced at recommended intervals. I have no reason to believe that the newer ExactFit Brand belts are any less robust than the Bucci belts, so, in short, I'd use an aftermarket belt any day over the expensive OEM Gates belts.
