FZR Fork Vs Seca II Fork: The Differences
Posted: Wed Feb 29, 2012 10:54 pm
Here are the things I found which are different between the Seca II fork and the FZR600 fork internals.
The fork pistons on the FZR600 are about 2" longer than the fork pistons on the Seca II fork:

The damper rods on the FZR600 are about 1/2" shorter than the damper rods on the Seca II fork. Both damper rods have the same size and number of holes:

The FZR600 springs are shorter than the Seca II springs and the FZR spacers are longer than the Seca II spacers. The combined length of the FZR600 spring/spacer is longer than the Seca II spring/spacer (the FZR spring is on bottom; the stock Seca II spring is in the middle):
