I just changed the countershaft sprocket on my 2010 F650GS. I added a tooth. The only place I could find an 18 tooth sprocket was Tourtech. I have put about 500 miles on since changing it, and I have dropped about 500 rpm. When I added the Tourtech saddle bags, I gave up several miles per gallon. Their boxes hang out on the side like mini walls. I am pleased to report interstate mileage has increased 4 miles a gallon. I have not noticed any struggle to take off from a stop. Now if I could find a 38 tooth rear sprocket.........
