I've been looking at them for my YZ125.
I'll be going for the solid ones with both O-rings.
It's hard to believe that KYB would leave the pistons solid without the relief holes for 12 years, if having the piston solid wasn't for a reason. I'd really like to know that reason.
They have to be aware of the pistons exploding. Is the free piston the cheap part that prevents more expensive damage?
Is it solid for performance reasons?
What do they recommend? Holes or no holes, solid or open? 0-rings or no o-rings?
If anyone has a contact from KYB engineering that can answer these questions it would make it a lot easier to choose a free piston replacement.
And of lesser importance:
Why are the pistons open on some bikes, but solid on SSS? Is the solid piston a part of what makes SSS great?
There was a thread on this a while back with some suspension guys including ML chiming in.
I appreciate the feedback, and that drilling the holes mostly prevents the pistons from exploding, but it would be great to know from KYB what they recommend on the question above and why.
Have a great day!
