OEM Kawasaki Z125 Pro Axle Flanged Lock Nut - 12mm

The axle bolt gets all the attention, but it's the nut on the other end that actually keeps your rear wheel from working loose. This is the genuine Kawasaki 12mm flanged lock nut, part# 92210-1513 — the factory fastener that threads onto your Z125 Pro's rear axle and holds the whole wheel assembly clamped tight.

The flange spreads clamping load across a wider surface so the nut seats evenly, and the locking feature helps it resist backing off under the constant vibration and load cycling of the drivetrain. That combination is exactly why you don't want to reuse a tired, rounded, or stretched lock nut — a fastener that won't hold torque on your rear axle is not the place to cut corners.

If you rounded the old one wrenching on a stubborn axle, or you're just refreshing hardware during a rear wheel, tire, or chain-and-sprocket service, this is the correct OEM piece: right 12mm thread, right flange, right locking spec. Thread it on, torque to spec, ride with confidence.

Genuine Kawasaki. Direct fit. The right nut for the job.
