Hi Pekes, I recently purchased a 2017 VX300 and looking to change the rear tire and possibly the gearing to do the same as you, lower engine speeds at cruising speed. I noticed the suggestion of Shinko 705 130/90-17 and wondered if you were still happy with the change? I currently have 15/46 gearing and stock tire on rear and fairly happy with engine speeds but wonder if I couldn't get a little more with a 44 or 43 tooth rear sprocket WITHOUT the ECU alarm issues. I hope these questions aren't terribly redundant as I've searched the last 3 or 4 days. Thanks; Ken or Bullwinkle or anyone else please feel free to respond with your experiences.
