Also, I’ve just remembered. I took a Buell out for a test ride back in around 1996’ish.
That was belt driven plus reasonably powerful. It just wasn’t powerful enough for me at the time, coming off a triumph speed triple. I rode the Buell for around 50miles without any form of issue regarding the belt. I liked the bike generally, it simply wasn’t fast enough for me at the time. Hence I bought my second speed triple and not the Buell
