Motion Pro PBR Chain Tool

Chain tools are nothing new. I suspect that their origins go back to about 15 minutes after the first functional roller chain was conceived in the late 1800s. But that hasn't prevented people from coming up with more practical and ingenious motorcycle chain tools for removing, installing and sizing motorcycle drive chains.

And that is precisely what Motion Pro ( has done with its new PBR chain tool (part #08-0470; $95.99). The tool's name is derived from its separate functions: "P" for pressing on a new side plate; "B" for breaking an endless chain or removing links; and "R" for riveting the master link on a new endless chain. The cleverness of this tool's design is in the little square anvil block that is repositioned for each of those separate operations. The anvil has the P, B and R letters on three of its four corners, and the matching "Press," "Break" and "Rivet" words are printed on the tool's main body. Each of the anvil's three working sides is specially shaped to carry out its intended function. The PBR also has two threaded pressing bolts, one inside the other, with a stout handle for holding the tool in place when the chain is still on the bike. The tool can be clamped in a vise for easy operation when the chain is off the bike.

To use the PBR, you place the anvil in the tool so the letter for the desired operation is adjacent to the corresponding word on the body, then put the chain in place. If you are breaking the chain, you first position the anvil with its “B” adjacent to the body’s “Break,” then screw the outer bolt down lightly against the side plate for stability. Using a 14mm wrench, turn the inner bolt until it completely forces the chain pin out the other side of the chain.

To install a side plate on a new chain, you first put the chain in the body with the master link slipped in place and its open end facing the press bolts, then lay the side plate on top of the exposed link pins. For this operation, put the anvil on top of the chain so the “P” is nearest to “Press,” then use a 17mm wrench to turn the outer bolt until the plate has been fully pressed into place.

Now to rivet the master link. You start by repositioning the anvil under the chain with the “R” adjacent to “Rivet” and the new side plate facing the press bolts. The PBR comes with two different riveting tips: a quad stake tip, used for solid link pins, and a hollow nose tip for hollow pins. You slip the prescribed tip onto the end of the outer press bolt and, one pin at a time, flare the tip of each pin using a 17mm wrench.

The PBR is designed for use only with 50-series chains (520, 525, 530), but it works equally with O-ring and non-O-ring types. Plus, it comes with instructions that are much more complete than those I have described here. This is a professional-quality tool that will serve just as faithfully in a bike shop as it can in a rider’s personal tool collection.
