WISECO WCA128 — CRANKSHAFT ASSEMBLY
KTM 85SX 2018-2025

The WCA128 is the same crankshaft assembly supplied in Wiseco's bottom-end and engine rebuild kits, available here as a standalone
unit. Suitable for partial rebuilds where the bearings, seals and gaskets are being reused or sourced separately.

CONSTRUCTION
Precision machined crank webs developed and tested for ultimate strength and durability. Run-out and critical dimensions held to
strict tolerances. Timing keyway inspected for accuracy before leaving the factory.

CONNECTING ROD
Copper-plated and heat-treated to optimise material properties and maximise bearing wear resistance. Surface treatment removes
residual stress risers and smooths surface blends for improved load resistance and service life.
