FALICON produces The Supercrank:
This particular Super High
Performance crankshaft (moderate lighten, balance & polish) is the
“ultimate” modification for knife-edge performance.
The OEM crankshaft is blueprinted to the best combination of oil clearance,
moderate lightening and precise tolerance for your specific application. The
crank throws are contoured and polished to a mirror finish, improving oil flow
and reducing crankcase turbulence. Each crankshaft is custom balanced to the
reciprocating weight and intended rpm range, for use with or without the OEM
counterbalance (on some models).
APPLICATION: HONDA CRF 450 R 2010 – 2012
