Rode a 2017 yesterday about 15 miles - I noticed:
*My hands were tingling from the vibration after about 10 minutes of twisties at moderate rpms.
*The digital display for tach, gear indicator, and speed were so tiny as to be illegible without reading glasses for anyone with less than 20-20 vision. I don't intend to be wearing bifocals to ride just so I can see the instruments -- that is absolutely the stupidest design flaw I think any half-witted engineer could possibly overlook.
Besides that, it was a fun ride the pea-sized digits on the instruments alone were enough of a deal-breaker for me. I'll be sticking with the K75 probably for life.
