KP23 2-Piece Maxload USSSA Bat Overview
The 2026 Miken KP23 2-Piece Maxload USSSA Slowpitch Softball Bat (MSU6KP125L) pairs a 12.5" V2-Flex barrel with Miken's Maxload end-loaded swing weight and a stiff Pro Flex handle built for hitters who want raw power transfer over forgiveness. The two-piece construction isolates the handle from the barrel for a distinct connection point at contact, while the low-profile A1 knob keeps your bottom hand locked in through the swing. It's approved for USSSA slowpitch softball play as well as ISA and NSA leagues, backed by a 1-year manufacturer's warranty, and available in 25, 26, 27, and 28 oz.
Key Features of the KP23 125L Maxload
12.5" V2-Flex Barrel
V2-Flex barrel construction uses variable layups and exclusive resins to maximize the barrel's compression area at contact, extending the effective sweet spot across the full 12.5" hitting zone.
Pro Flex Handle
A stiff handle built for maximum power transfer. Where Miken's Mid Flex handles trade a little stiffness for reduced sting, the Pro Flex handle on this two-piece build keeps as much energy as possible moving straight into the barrel on contact.
A1 Knob
The A1 knob is a low-profile, ergonomic design that keeps the bottom hand anchored through the swing without adding bulk at the base of the handle — a small detail that helps maintain barrel control on the Maxload's heavier swing weight.
Maxload Swing Weight (.5 oz Endload)
A .5 oz endload shifts mass toward the barrel for hitters who want maximum pop on contact and are comfortable managing a heavier, end-loaded swing.

Frequently Asked Questions
What barrel size does the Miken KP23 MSU6KP125L have?
This bat features a 12.5" V2-Flex barrel — slightly shorter than the 12.75" barrel on the Miken KP23 1-Piece Maxload USSSA bat and longer than the 12" barrel on the KP23 Pro Maxload, using variable layups and exclusive resins to maximize the compression area at contact.
Is this bat one-piece or two-piece construction?
The MSU6KP125L is a two-piece design, so the barrel and handle connect at a distinct joint rather than acting as a single fused piece. That connection point changes swing feel compared to Miken's one-piece KP23 builds.
What does the "Pro Flex" handle do?
Pro Flex is a stiff handle designed for maximum power transfer into the barrel on contact. It trades some of the sting reduction you'd get from a Mid Flex handle for more direct energy transfer, so it's best for hitters who prioritize raw power. If you'd rather have more give, browse the Mid Flex builds in the Miken Slowpitch Softball Bats collection.
What does "Maxload" mean and who is it for?
Maxload means the bat carries a .5 oz endload, shifting weight toward the barrel for maximum pop on contact. It's best suited to experienced hitters who already generate strong bat speed and want more mass behind the ball, rather than first-time slowpitch players.
What weights is this bat available in?
The Miken KP23 125L Maxload is available in 25 oz, 26 oz, 27 oz, and 28 oz.
What certifications does this bat carry?
It's approved for USSSA, ISA, and NSA play. Note this is a USSSA-stamped bat, not a USA/ASA bat — if you play USA/ASA-sanctioned softball, see the Miken KP23 2-Piece Maxload USA/ASA Slowpitch Bat instead.
How does this compare to the standard KP23 or KP23 Pro?
This 12.5" two-piece build sits between the KP23 1-Piece Maxload (12.75" one-piece) and the KP23 Pro Maxload (12" one-piece) on barrel size, but is the only one of the three built as a two-piece bat with a stiff Pro Flex handle. All three share the same Maxload endload and USSSA certification.
What's the warranty on the Miken KP23 125L?
It's backed by Miken's 1-year manufacturer's warranty against defects in materials and workmanship.
