HOT RODS complete crankshaft for KTM SX 125 from 2007 to 2011

HOT RODS offers this complete crankshaft for KTM SX 125 from 2007 to 2011. The crankshaft is the engine’s main shaft: the rod turns it and it drives the clutch and gearbox.

Why a complete crankshaft?

The benefits:

• Ready to fit, no specialist needed to press in a rod.
• Bottom end renewed in one go.
• Often cheaper than rebuilding a badly worn crank.

Why choose HOT RODS?

Hot Rods crankshafts come assembled and trued: double-forged 8620 steel rod and hardened crankpin (58-62 HRC), a ready-to-fit bottom-end rebuild.

When should you replace the crankshaft on your KTM SX 125?

Unusual vibration, a deep knock that follows engine speed or play in the con-rod: the bottom end needs a rebuild.

The manufacturer publishes no hour interval for this model: have the con-rod play checked at every piston change. Cross-Mania guideline: rebuild the bottom end every 2 to 3 top-end rebuilds.
