初心者の自分がサスを変えてどうなると思いつつの交換でした
I'm looking forward to touring in the future
How was the MC22 before it was installed?
It was fluffy and had a sensation of slipping in the corners.
How long did you wear it and run?
80km
What has changed since you put it on?
There was a feeling that the car body became lighter, and the anxiety in the corner was reduced.
Did you compare it with other products?
The rear suspension of CBR250RR was not sold by others, so there is no comparison.
Please give a message to those who are wondering whether to purchase from now on.
It was an exchange while I was a beginner thinking about what would happen if I changed the suspension, but I am very satisfied with the change.
I'm looking forward to touring in the future.

またがった瞬間から、しなやかなサスの動きを感じることができました
From the moment I straddled, I could feel the supple movement of the suspension.
How was the MC22 before it was installed?
I used to OH the normal, but I could not deny the feeling of lowering because it was flat, so I was riding with the preload as the strongest.
However, at the strongest preload, I was worried because I couldn't make a sufficient stroke with my weight of 67kg.
How long did you wear it and run?
About 20km
What has changed since you put it on?
From the moment I straddled, I could feel the supple movement of the suspension.
I didn't feel an extreme buttock, and I felt that the balance with the F suspension was good.
Please give a message to those who are wondering whether to purchase from now on.
I think it is a very well-balanced product in terms of price, performance, and ease of installation.

まるで路面に吸い付いているかの様です
It's like sticking to the road surface
How was the MC22 before it was installed?
I was afraid that the rear suspension was pulled out and the ass bounced on a fine uneven road surface. I couldn't beat it.
How long did you wear it and run?
I finally ran 500km because the cab was in trouble (^^)
What has changed since you put it on?
There is no sensation of the ass bouncing and playing, as if they were sticking to the road surface. The preload is also adjusted from our weight at the shipping stage, and I am looking forward to riding it.
Please give a message to those who are wondering whether to purchase from now on.
If anyone is riding the genuine product, we definitely recommend replacing it. If it is genuine, it will be a player for about 30 years, so it's refreshing! !!

リアサスペンションがへたってきた時のサイン
Sign when the rear suspension is worn out
・ During cornering, the car body becomes fluffy and the behavior becomes unstable.
・ The feeling of contact with the road surface is weak, and it swells due to cornering.
・ The bike bounces due to uneven road surface or deceleration zone, so you cannot run with confidence.
・ I feel that the car body is twisted at highway corners and highway seams.
・ Seat height drops too much when riding
・ Almost no effect can be felt even if the preload is adjusted.
For rear suspensions that have not been overhauled for years, the damage inside may be severe and OH may be difficult or the OH cost to restore the original performance may be high.
ダンパー（減衰装置）の劣化が主な原因です。サスペンションは新車時（新品）をピークに、ダンパーの中にあるオイルや、部品が劣化していきます。
一般的に、ストリートでの使用を前提とした場合、10,000kmから20,000km（または２年に１度）のオーバーホール or 交換が推奨されています。
（純正・社外品を問わず同じです）
もちろん使用環境によって個人差はありますが、何十年、何万キロも使うことを前提に設計されていないのです。
同じバイク、同じライダー、同じ環境でおこなった高負荷走行テスト。
走行距離が伸びるにつれて、オイルの汚れがひどくなり、オイル粘度が低下します。いわゆる水っぽい状態（シャバシャバな状態）になるわけです。
するとダンパー本来の役割が果たせなくなり、サスペンションが急激に伸び・縮みしたり、路面の凹凸を通過した際、バイクが跳ね続けて不安定になります。
これがダンパーが劣化した状態、リアサスがへたった状態です。
乗り心地が悪くなるだけではなく、バイクの運動性能（安全性）におおきく影響します。
グレーの写真はフロントフォークオイルですが、リアサスのダンパーオイルも最終的に同じような状態になります。

Ride for a while, and once you get used to it, you can adjust it yourself and enjoy the changes.
Spindle rod (damper rod)
The spindle rod, which requires abrasion resistance and smooth stroke, is made by heat-treating the highest quality high-tensile steel to achieve outstanding strength and durability.
The surface is polished and mirror-finished in micron units, and then hard chrome-plated to increase the surface hardness.
spring
Uses evenly spaced springs that do not change the rate during strokes and make it easy to adjust the settings.
Designed to achieve both light weight and long life, the high-precision springs produced under quality control that meets international standards continue to perform as specified even under harsh usage conditions.
The material is the finest silicon chrome steel. Corrosion resistance and long surface hardness have been achieved by powder coating, which is resistant to scratches and has excellent flexibility.
