Worth the price.Ninja250SL/The OEMFork of the Z250SL is not the most comfortable to ride on the street, as it is soft and has a thrust to it that comes back to you during cornering. Still, the light weight of the vehicle can be deceiving. "I think I'll leave it as OEM - I'll just add a Preload Adjuster..." However, I took the plunge and purchased the Upgrade Kit, partly because I had replaced the Rear suspension with YSS.
For installation, since the fork cap is a C-ring type, an SST with a portion of the clamp cut off is required, but anyone who can change the fork oil can install it themselves.
In case of PD ValveUnit Purchase, many models require orifice modification, but in case of Z250SL, for some reason, there is no description about orifice modification even in Instruction Manual. Large enough to have little or no damping.
Normally, it is necessary to cut the collar for the PD Valve, but the Upgrade Kit comes with a pre-cut collar, so this work is not necessary. It is a hassle to cut the collars horizontally, so it is good that you can install the collars by yourself as long as you can remove the fork caps.
The kit included 30W Fork oil, and the instructions were to put in 300ml each. However, reading some of my predecessors' blogs, etc., I found that some people were installing the kit with the OEM specified 10-15W and the specified amount (about 350ml), so I tried setting it with the latter for the time being. If I feel it bottoms out or is too soft, I will change it to 30W.
The first thing you'll notice when you install it is It's kind of softening." I thought it would be harder because of the Reinforcement Spring, but it was softer in the beginning, and the thrust when riding on the street was drastically reduced and the ride quality was improved.
I went touring with it and attacked the descent of a certain Tsubaki Pass quite seriously, but it held firm against sudden braking and did not bottom out, allowing me to attack with confidence. Even a high degree of freedom in line taking is now even freer. No one rides this Motorcycle and says it can't turn. Cornering has become so much easier that it seems to be.
I also drove Izusuka after that, and to begin with, Izusuka with 250 is not fun because even if you are always at full throttle, you are left behind by the litters, but even at high speed cornering, the front does not come back during cornering, so the line is perfectly set and very comfortable. Of course, since it is an SL, the line can be changed freely even from full bank, but anyway, the increased sense of ground contact of the front gives me a feeling of security.
Preload AdjusterSingle Body was about 10,000, so 35,000 is a good price considering it includes PD Valve and Reinforcement Spring. I think it is worth it. If you are not sure about the price, you will not regret installing it.
The only drawback is that the PD Valve damping adjustment can only be made by draining the Fork oil and removing the PD Valve under the Spring. Although this is unavoidable due to the system of retrofit damping adjustment, the C-ring type top cap is troublesome to remove and install, so I only do it when I change the fork oil, and I do not feel like removing the fork and adjusting it again just because it is a little different after driving.
If you change the front and rear suspension and put on high grip tires around α13-SP It's hard to fall over on a public road unless you're doing it on purpose. It will be a CorneringMachine that makes you feel like you are a part of the world. It makes touring fun because you have a sense of security that you can definitely turn, and you may think that you have become good at it, but be careful, because just because it is a motorcycle that anyone can turn does not mean that you have become good at it.View Detail
