My Mandello S is still running strong with absolutely no problems at 2500 miles.
The aspect of this bike that I do not hear enough about in owner reviews is the acceleration performance it offers. The thing gets up and GOES. It pulls hard in every gear. Even in 6th, a roll-on at 55mph is greeted by a noticeable surge forward with no hesitation or struggle. It's a very fun bike to ride and I have enjoyed it a lot. It also definitely has the Guzzi DNA from past machines that everyone loves.
I still haven’t tried a WFO standing start acceleration test using the quick shifter but rolling it on from below 5K RPMs it seems to pull like a two stroke. Pulls when you twist the throttle but then winds up to redline in a second or two.
If you aren’t ready for that in first gear it hits the rev limiter and cuts out for a second or two.
