Free Piston Kit for the replcement of KYB AOS (Twin Chamber) Front Fork
The material is an anodized aluminum alloy instead of the plastic of the stock product, which increases the strength and prevents breakage.

The stock type is designed to optimize the pressure balance so that it does not affect the feeling of the stock product.

LT type is as light as possible and has reduced friction.
By reviewing the pressure balance, a more comfortable feeling is achieved and the burden of riding is reduced.
In addition, the feeling can be changed to the same as stock by adjusting the amount of oil.
The whole movement also has a progressive feeling.

Points of Attention

* If there may be an instruction manual included, it will be written in Japanese.

Well made looks cool

I run sss forks on my 08 crf250. I was doing a complete rebuild and went ahead and upgraded the pistons as I figured they would be damaged. They indeed were cracked. After the rebuild the forks feel so much better. Very happy with these.Great free pistons. I've had race tech, and both types of zeta. If you like your ride a little more plush on the mid to bottom stroke, get the open cage design. If you like the stock feeling and a little more resistance through the stroke, get the closed design.
