  • You WERE listening to only a half a V4 Ducati engine…

I recently returned to riding following a 25+ year break after selling my first bike, a 1993 BMW K75S when I left the USMC in 1999. My uncle is responsible for getting me on a motorcycle initially and with this recent return. I’m very fortunate to have purchased my dream bike in the summer of 2024, a 2023 Triumph Speed Triple 1200RR, and I’m well aware of my limita... more
