 YFZ-450 to a 513cc Clawhammer

This kit will convert your YFZ-450 to a 513cc powerhouse.  This third generation kit is the best combination of power and durability.  Rather than bore out a stock cylinder, we use a completely new casting with heavier walls and larger water jackets.  This Tall Cylinder works with our Long Rod Billet Crank, but it doesn't need a spacer plate - the best of both worlds. 

Includes:

Falicon Billet Stroker Crank 68mm
Falicon Knife Rod - Long
Falicon Tall Cylinder - 98mm
Piston Kit (98mm) Stroker Compression
Wide Heavy Duty Cam Chain
SS-Y-450HD Adjustable Cam Sprocket
Shorter Top Motor Mount
Oil Line Extension kit
Longer Head Bolts (4)  

Please specify ATV-style (YFZ) Piston or Bike-style (YZ-450F) Piston.

YZF 450 Specifications:
These kits fit all 2003 to 2007 models and use the stock stroke. However, because the 2006-2007 models have a 1.4mm longer stroke the resulting displacement for a given piston size is increased according to the table below.
