Navy from knob to end cap, with KP23 in red across the barrel. This limited colorway of the Miken KP23 Maxload One Piece is a hard bat to track down, which is exactly why it lives in our Rare Finds section! The KP23 is Kyle Pearson’s signature model, a bat line built around a hitter known for consistency, and this version is the stiff, no-nonsense one-piece of the family. Dark navy blue finish, red Miken logo down the back, a navy grip that blends right into the handle. It looks clean, it swings honest, and there aren’t many of them around.

The one-piece composite design is the heart of this bat. Handle and barrel are a single stiff unit with no joint between them, so nothing flexes or gives at contact and the energy from your swing goes straight into the ball. Hitters who like to feel exactly what they hit tend to love that. The Maxload swing weight adds a 0.5 oz end load, enough extra barrel mass to boost power and distance without making the bat a chore to get around. The barrel is 12.75 inches, a mid-length design that keeps the sweet spot balanced and the bat responsive through the zone. Put together, it’s a setup that suits a strong, repeatable swing more than a big hack. This KP23 is approved for USSSA, ISA, and NSA slowpitch play, comes in 25 oz and 26 oz, and carries a one-year limited manufacturer warranty.

Limited colorways like this are the reason our Rare Finds section exists. LongballBats.com has been the Bat Performance Experts since 2016, and with more than 100 years of combined baseball and softball experience on staff and tens of thousands of bats sold, we know which bats are worth chasing down. We carry one of the largest selections of the brands we sell, plus sold-out and limited edition models you won’t find sitting on most shelves. If you’re deciding between this one-piece KP23 and something with more end load, like the Miken DC41 XTREME Supermax, we can walk you through how they actually differ in the hands. Contact us and we’ll help you pick, while this one is still here!

QUESTION: Should I order this bat stock/untouched or Heat Rolled with Progressive Pressure?
ANSWER: If you order your new bat Heat Rolled with Progressive Pressure, it will be delivered to you completely and evenly broken in. This process adds 20-40ft of distance to your solid hits, increases consistency, improves durability and adds 2-3 business days of lead time to your order. If you plan to use the bat in an official game or event, please verify the legality of our process with your league or sanctioning body before use. We (LongballBats.com) do not encourage the use of a Heat Rolled bat in any game or event where it is against the rules. Click here for details about our process!

QUESTION: Is a one-piece or two-piece bat better for slowpitch?
ANSWER: Neither is better. They’re different tools! A one-piece like this KP23 (or its original colorway) is stiff the whole way through, so you get a direct, solid feel and immediate feedback on where you hit the ball. Hitters with a compact, strong swing and good barrel control usually prefer that, because nothing is flexing behind the ball. A two-piece has a joint that lets the handle whip a bit and softens the feel on mishits. If you like a bat that feels like one solid piece of lumber and you square the ball up consistently, go one-piece. If your hands sting easily or you like some whip, look at a two-piece.

QUESTION: Why does the KP23 have a 12.75 inch barrel?
ANSWER: It’s a middle ground, and a deliberate one. Longer barrels in the 13.5 to 14 inch range give you more hitting surface. Shorter 12 inch barrels pack the performance into a tighter area. At 12.75 inches, this KP23 keeps most of the forgiveness of a longer barrel while staying quick and well balanced through the zone. Paired with a half-ounce load instead of a full ounce, it makes for a bat that hits with authority but still goes where you point it. That fits the consistent, line-drive style the KP23 name is associated with.

QUESTION: Is this Miken KP23 Maxload One Piece legal in USA/ASA or senior leagues?
ANSWER: This version is approved for USSSA, ISA, and NSA slowpitch. It is not a USA/ASA bat and doesn’t carry that stamp, so it can’t be used in USA Softball leagues or tournaments. It also isn’t a senior bat. Miken makes the KP23 in other versions for other associations, so be sure you’re matching the stamp to your league before you buy. If you contact us and tell us where you play, we’ll confirm whether this one works (or point you to the version that does!)

QUESTION: Should I swing the 25 oz or 26 oz KP23?
ANSWER: With a half-ounce Maxload, the answer is closer to your normal weight than it would be on a heavily loaded bat. If you swing a 26 oz balanced bat now, the 26 oz KP23 will feel a touch heavier out front but very manageable, and the 25 oz will feel almost identical to what you’re used to. Hitters who rely on bat speed and placement should lean toward the 25. Stronger hitters who want a little more behind the ball can take the 26. Since this is a limited colorway, it's smart to act quickly if the weight you want is still available!
