2007 and 2011 KLR 650

I am a new member and want to know if it is best to change the rear sprocket on these bikes to lower RPM when in 5th gear or change the counter shaft sprocket, which I have done on other bikes. I am new to KLRs and want to cruise at a lower RPM on either bike. Recommendations? On both of my bikes, with the stock sprocket they tach 4K at 60 mph. John

The larger the front sprocket the slower the chain will wear, due to diameter of the sprockets.

1 tooth on the front (up or down) is about equal to 3 teeth on or Off of the rear sprocket.
Have fun.

I run a 16 tooth when traveling a lot on the road and a 14 tooth for extreme off road with the stock rear sprocket.

The countershaft sprocket cost less and is easier to change than the rear. Also, easier to carry a spare in case you want to change gearing on a trip. I suggest a prevailing torque nut (lock nut) from Eagle Mfg & Eng to make changing easy - no more bending that big lock washer.

I recommend the front as well. The front sprocket wears out a lot faster anyway chances are your front sprocket is close to needing replaced anyway. As long as you keep fresh front sprockets on there your chain will last longer
