As a side note not mentioned the shaft check plate is great for outdoors with taller heavier riders. Short ligth riders dont like it and it is usually taken out. Also to mention is that there is a small ball and spring that has a check plate and the hole in the check plate can go from no bleed, .5mm .75mm . 1.0mm, 1.25mm, 1,5mm, 1.75mm all the way up to 3mm. RT has a poor mans version of this and is incorporated into the shaft nut. I have had several Showa Factory A-Kits and beign a talller rider I have kept a 1.5mm bleed for MX and a .5 for SX. Allows me to add more compress and not really effect the rebound as suggested. Also not mentioned was the pre-load adjuster is a click adjuster and rotates so the there is no coil binding when compressing making it smoother Also not mentioned all the clickers are 1/2 clicks so double what OEM has. Just makes it that much more tunable in combination having a larger dia shaft that will displace more oil into the stacks. Same think on Facty A-Kit forks that have 16-18mm dampner tubes...The BV finally become very tunable as the larger dampner rod displaces 3x time more oil into the BV.
Looks like A kit is a rip off. There's no reason they shouldn't be using this in stock bikes. These parts are not hard to make or expensive to make at all.
