• It probably wont work. 
  
  
  
  YFZ450 (Early 04-05) Left
  LT500R Right
  
  Shows how over-square and short stroke the high performance 4 stroke 450's are. Also is an indication on how much the LT500R is a beast.

• Not really the stroke its more like the length of the rod being how short the cylinder is on the yfz.

• If only the 500 had a smaller stroke would be able to rev way higher.

• I think advancements in metalurgy should allow engineers to re-design the crankshaft & connecting rod using lighter stronger materials to let the big 500 rev up higher than 9000 RPM.

  stock raptor 700 revs to 9000 as well and is a larger thumper. so i agree that zilla can be made to rev higher.

• Anyone have any input about using the CR500 rod to fix(help) the bad rod angle of the Lt500?

• Hey guys. The CR500R rod is 144mm long, and the KX500 rod is 145mm long. Not really worth doing. I got some contacts in case anyone wants to spend some major cheese and have some made...
