I'm someone who likes to open up the air for FFork on a regular basis.
Purchased for air breeder purpose.
Because you don't have to remove the fork cap every time you want to release the air pressure.
It is easy to open the air.
By the way, FFork air opening is a recommended maintenance.
By opening the air when the FFork is extended by Jack or other
Cornering's FFork movement calms down.

[Preload Adjustable Range]
・-5mm - +10mm
Front suspension preload can be adjusted by replacing the stock top cap.
The preload adjustment range is set from -5mm to +10mm, which is suitable for various situations such as off-road riding or setting to suit your weight.
By applying an initial force to the spring, the nose dive caused by sudden braking is reduced.
Equipped with an air bleeder that allows high pressure air that builds up inside the suspension due to high speed or heavy riding to escape without the use of tools.

The installation was done reliably by checking the video etc
After a month or two of wearing it, when you start to wear the Front up
Immediately there was an Oil leak at the point of pulling the Air out
I couldn't fix it by hardening it or softening it or OHing the Fork
I've reverted to the OEM Cap

SEROW is also often driven on the on-road, and the soft Front is inevitably Stop & It becomes a Stress on the go, but I wonder if it's reduced after installation?
IIRC, I'm going to replace the Tire with a Two-Ten next time, so it might work better for me
Button without Air (?) When you push the button, the air is released and I found out that air can accumulate unexpectedly
A few drawbacks of the product
When installing the top cap, use the 27mm glasses wrench or the Socket You need a wrench It's a size you don't get to use very often, so it's better to get a motorcycle shop to do it for you It may be cheaper than buying tools
Also, the product is not very strong, or soft, and it scratches quickly, and Adjuster a few times The beautiful gold will be torn to shreds if you use Wrench
It's more comfortable to use the OEM colors to put in the Fork as they are in a certain Racer imprint I've read that it comes, and I'd like to try it eventually

I put it on a bit as I often ride two people
-This product can be adjusted in the range of +5 to +10mm
In the meantime, don't make it the strongest, give it +5mm, and extend the suspension and air bleeders
When I adjusted it, I was surprised at how many different looks it made
Motorcycle habits change, so I'm sure people will have different opinions
I found it to be very good for me
If you think it's too expensive, you can apply 5mm of washer first and see how it goes
