Proper final-drive maintenance is key to ensuring your motorcycle operates smoothly and safely. Many of us keep a watchful eye on chain lubrication and tension but overlook rear wheel/sprocket alignment—a recipe for excess chain, sprocket, and countershaft-bearing wear.
The tool holds a sighting rod perfectly aligned to the sprocket, creating an accurate visual representation of the angle at which the sprocket meshes with the chain. If your rear wheel (and your sprocket along with it) is not perfectly in line with your chain, the deviation of the sighting rod will be easy for your eye to see. Once set, tighten the rear axle nut with the appropriate amount of torque and be on your way. Using the alignment tool might require the removal and replacement of your chain guard, but that’s usually a simple process.
Most thinking holds that lining up axle adjusters with indicators on the swingarm is “good enough.” Those graduated marks aren’t meant for finite adjustments, however, and there’s a chance they’re not identical from side to side. What’s needed is a remarkably accurate tool you already have and an extra frame of reference—that’s where your eyes and the Motion Pro Chain Alignment Tool comes into play. The device slips over the rear sprocket and clamps against its face, a nylon thumb screw holding it firmly in place. Your eye does the heavy lifting from there.The Chain Alignment Tool is designed well; the body is made of aluminum with an anodized finish, and both small thumb screws are plastic—sensible considering they’ll only ever be finger-tight. The sighting rod is made from steel for increased durability, details like this are what Motion Pro is known for.
The Motion Pro Chain Alignment Tool has become a go-to among the Rottweiler staff, especially at the racetrack where we’ll make multiple adjustments throughout the day. Inexpensive, well made, and simple to use—it doesn’t get any better than that.
Your bike's chain and sprockets have a tough job to do, and it's not like they get to work in a very clean environment. So even if you're diligent about cleaning and lubricating your chain as outlined in our last MC Garage video (How To Properly Lubricate Your Chain), your chain and sprockets will eventually wear out. When your drivechain wears out you can pay a shop to replace the parts or you can invest in a chain breaking and riveting tool like Motion Pro's PBR tool and tackle the job yourself. In this video from the MC Garage, Senior Road Test Editor Ari Henning will show you how to replace an endless sealed chain and front and rear sprockets. Included in this video are tips on replacing the sometimes difficult-to-remove countershaft sprocket as well as advice on master-link choice and how to properly rivet a new master link.
