Do you know the piston sizes vs the two calipers?

I just serviced my rear brake...well, I initially just went to slip in new pads, but it turned in to more when I saw that the pin that the caliper floats on as bent. Witness marks shows that it's been bent for a long time. I always thought the stock rear brake felt pretty good, now after fixing that pin, it's very, very strong. Just tossing that out there.

Good luck on the swap and keep us in the loop on what's up.

Yes it has been done IIRC.....back when the :"$21 mod" first came out. There wasn't a ton of uptake because there is nowhere near the improvement that there is with the front brake.

I don't know if you have a Gen1 or Gen2......I certainly wouldn't bother upgrading a Gen2 rear brake. As far as the Gen1 goes, mine are stock except for pads and a S/S line and I can lock up the rear on dry pavement at will so I decided that any time/expense on an upgrade was a waste......that said, my use is lightly loaded and I run knobbies; it's possible that with street tires and/or a heavy load or 2 up that the benefits may warrant the upgrade. ....In that case, it may be simpler to go with the Gen2 caliper and swingarm and there are other benefits to that (better chain adjusters, etc.)

....anyhow, that's the history.

The caliper need to be shave a little in the back to fit but even after removing 1/4 there still a lot more meat then the stock caliper .

Tommy,
The rear brake pedal on a KLR650 generally has to stroke pretty far down with the single piston caliper.
How is the pedal travel with the twin piston caliper?
