If you look about 2/3 way down in the following link under the title “PICTURE #4” it says 57001-112-1 supersedes 57001-532. I don’t know if that is true or not, but it may be worth asking a dealer if that is a true statement.



If it is true, and if tool #57001-112-1 will work on your KZ1000, you may want to check out the auction below. It seems to me you could buy and use the tool and if you no longer needed it you could sell it and probably not take much, if any, loss. Ed

All of the inline 4 bangers in the world and this tool is an elusive little fella.

The part numbers are as provided in the respective FSMs.

Am thinking the 57001-532 was designed to fit the KZ1000's larger pistons.

The Partzilla listing for 57001-532 specifies its use for KZ1000 models.

Good Fortune!

The T57001-112 works only on the 66mm or so pistons. The curvature of the actual pieces that butt up against the piston don't come close to matching the 70mm pistons of the KZ1000 motor.

The T57001-532 ring compressor I have used on up to 73mm pistons in KZ1000 motors.

If you have ever used one of these ring compressors, you would never go back to anything else. I could put the cylinder down on the pistons in about 10 minutes by myself!!!!

When I was going through some very serious health problems a few years back I sold mine.

WHAT A MISTAKE I MADE!!!!

I have one for the 900 and wish I had the +72mm one... darn it.
below is the result of using my 112-1 compressor on an old KZ1000A1 piston.
yes it is tight enough that the points of the cups might be digging into the aluminum of the piston.
Note the giant gaps in the center of the compression cups.... and how the piston rings are not compressed into their grooves!!! I'm afraid I'd break the rings trying to shove the cylinder block down on four pistons...





I wish I knew how to use this on the larger bores.... I have a 1075 Wiseco kit with a different cylinder block bored, honed, piston fitted and ready to use on my bike, but I am not risking breaking rings with the 112-1 compressor.

What's wrong with aluminum strips cut from beer cans and hose clamps?

I found that the thin aluminum made it passed the edge of the cylinder wall and caused problems.
I just deburred my hose clamps and used them by there selves with a lot of motor oil and kept loosening them unit they slipped easily.
I also used thin metal barbeque skewers to hold the pistons level.
Work great

I do them 2 at a time. When the aluminum is just in the bores, I rotate the crank and the pistons slide right in. Still a PITA.
