Duke 390 - Front Sprocket Install-

Today I'm installing a 16T front sprocket on my 2018 Duke 390. The stock gearing runs a 15t up front and a 45t in the rear. Going +1 on the front sprocket with make the gearing slightly taller. This should mean less revs per mph than normal. While crusing 80mph the stock gearing usually has engine revs of 8000rpm. With the 16t front sprocket the revs should fall approximately 500-600rpm. This means the revs should now be ~7400rpm while at 80mph. Buy your 16T sprocket here: https://www.2wheel.com/driven-racing-...
