We’ve been monitoring the drive system on a twenty some year old “A” model KLR650 for several months and are astounded at how long the chain and sprockets have lasted.

The owner has just recently decided 48,000 miles is enough. Despite the fact that the components still have some life remaining, he subsequently installed two new sprockets (15/43) and top quality “O” ring rivet link chain. We here at Top Gun are hoping to study the old components and if successful will report on our findings later.

It’s obvious the owner of the KLR being discussed knows how to maintain a motorcycle and understands the importance of keeping a drive chain lubed and adjusted; which is why we gave him one of our first Chain Master upper chain control units to test early in the life of his 48,000 mile drive set. Since limiting drive chain slack contributes to longer chain life we believe, as does the owner, that our Chain Master had a positive impact on the high mileage numbers he attained.

The choice of a high quality O-ring chain, fifteen tooth “Supersprox” counter sprocket and JT 43 tooth steel rear sprocket were important ingredients leading to the high mileage that these drive components achieved The fact that the owner periodically adjusted his chain, cleaned it with WD-40 on a rag, and finally lubed it with Dupont chain lube also played a huge role. An additional aid to the long life of the drive system being discussed is the owner “flipped” the rear drive sprocket over at each rear tire change (great idea!!)

It’s a well-known fact that long travel bikes sustain more drive component wear over time than those with less rear wheel movement, especially when they are used off-road. The spectacular 48,000 miles of chain life achieved on his KLR650 must be considered in that context.

“Un Gran Bravo” for the KLR rider/maintainer who “pulled this one off”.
