AEROX Full Matel Crankshaft 64.7mm(+6.0)

Longer stroke. Broader torque potential. Built for clean, repeatable fitment.

This Full-Coverage Long-Stroke Crankshaft is engineered for Yamaha AEROX builds targeting a 64.7 mm (+6.0) stroke. Full-coverage crank webs and precision-finished journals support sealing area and rigidity, while OEM-matched interfaces help the assembly drop in cleanly (with proper top-end setup). Pair with the correct cylinder/head stack and fueling to realize tractable low-to-mid pull.

Highlights
🔹 64.7 mm Long Stroke (+6.0) — Expands displacement potential for stronger low-to-mid response after proper setup.
🔹 Full-Coverage Webs — Broad cheek coverage supports crankcase sealing area and structural stiffness.
🔹 Precision Interfaces — Main journals and tapers finished for straight, true running and reliable alignment.
🔹 Build-Ready Geometry — OEM-fit mating surfaces ease assembly and shim/clearance checks.
🔹 Tuning Friendly — Designed to work with appropriate cylinder height, combustion chamber, cam/port timing, and fueling.

Installation Notes

• Verify cylinder height/stack (base gasket/spacer) and squish/compression to suit the +6.0 stroke.

• Re-set cam timing / port timing and fueling/ECU or jetting as required for the longer stroke.

• Confirm big-end/small-end dimensions and bearing specs match your piston/rod kit.

• Check crankcase clearances and oiling; torque to spec and inspect runout before final assembly.
