Glad I traded up!
Since I rode with Len BarrelMotorcycle to purchase the GSX-S125, I felt that the Front suspension was soft, but the Rear suspension was stiff!
I bought the GSX-S125 because the engine is the best, but I was still disappointed with the stiffness of the rear suspension.
This time, we finally decided to take the plunge and replace the rear suspension spring!
The reviews on the Net are controversial, but after a day of testing today, I wish I had replaced it sooner! I wish I had replaced it sooner!
I've felt this before. "A feeling of a sudden bump on bumps and uneven road surfaces! on bumps and uneven surfaces. is now very Mild, and the Rear suspension has changed to the feeling that it is working well!
Moreover, no other minus factors were particularly felt.
We may not know for sure until we have been on it for a while, but at this point, we only have good things to say about it.
Although the price is slightly high and there is a Large oddity of replacing it by yourself, I think you will be quite satisfied if you replace it.
However, since I am a light person weighing 60 kg, my impression may be different depending on the person.
In case you are wondering, the Spring compressor I found on this site made it easy for me to replace it!
I did not cut the bump rubber because it was not mentioned in m-tech's Instruction Manual, but I will check it out in the future.
I did not feel any particular sense of bottoming out so far today.

Less thrust compared to OEM, but still feels lumpy.
The OEM rear suspension of the GSX-R125 tended to cause the rear to bounce when riding around town. For the purpose of improvement, m-tech's Spring (Color:The OEM pre-road was about 13mm, while the m-tech one was almost zero with a free length of 130mm. After struggling to hold the spring with PPBand using Pantograph jack for four-wheeled vehicles, we replaced it. The spring did not fit well in the lower spring holder. I checked to see if I had the upper and lower springs wrong, but the instructions were correct. It may be due to the grinding process of setting. I thought it would be fixed if I put a load on it and finished assembling it.
Checked Spring's fit into the receiver due to running load. As expected, it fit well under load.
Impression is that the OEM Damper was bouncing with Gap, but it is not bouncing anymore, but the Damper feels like it is sticking out. However, Damper's movement is not as good as OEM Damper's. However, the movement of the Damper is better than the OEM Damper, and the Rear of the Damper feels more stable in the Corner, which I personally feel is easier to ride.
The OEM sag is about 15.5kg and the m-tech sag is about 25kg, which is +10.5kg. The front end of the car feels more straight. I would like to fine-tune it after driving.
I think that the price of Spring alone should be a little lower than the price of OEM Damper, although it has been replaced by OEM Damper and its maneuverability has been improved. I guess it can't be helped because it is a motorcycle that is close to the local spec. in a foreign country...
