I like it.

Many users seem to use the OEM release of the ZZr1400, but I chose this one. I replaced the clutch master with this one right after purchasing the car, and I also replaced the clutch master at the same time, so I am not sure if the clutch lightening effect was effective or not, but I had enough time for a downhill touring of about 200km without any grip fatigue. However, when combined with brembo 17RCSMASTER, I feel that the stroke is a little insufficient, but there is no trouble such as difficulty in entering the GEAR. The installation is not particularly difficult as all you have to do is remove the OEM and replace it with the new one. View detail

K-FACTORY Clutch release

We use a Radial master 5/8 made by Nisshin in combination with a short lever.

I used to use the old model Release made by KFACTORY, but I wanted to make the Clutch a little lighter.
I purchased the new Type Release. 。 The result was somewhat lighter.

If the MASTER side is also changed to Small diameter Type, it can be expected to be even lighter.

The design and build quality of the old model was better than the new one. I felt that the design and build quality of the old model was higher quality. View detail

ZrX1200 DAEG Clutch

I purchased this product to reduce the weight of my ZrX1200 DAEGClutch. The quality of the product is very good. The feel is lighter than OEM.
I was not sure how it would compare with other companies' products, but I chose Kfhaku because it was more expensive. View detail

This is not enough.

The diameter is almost the same as the NORMAL diameter, so there is no large difference, but the internal structure is the same as the NORMAL diameter.
The slippery construction is supposed to reduce operating resistance.
The fundamental solution is not possible without changing the MASTER, so the OEMMASTER of KawasakiH2Carbon and
It is being used in conjunction with the brembo. This makes it lighter than brembo. View detail

ZX14 remedy for heavy clutch lever.

The stock size of the piston on slave is 35.7mm. Small changes here have big gains. K-Factory slave is 36.4mm with teflon wear ring that reduces friction. This already gives a good gain. I went with combination of RCS(Ratio Click System) 18 or 20 mm on the master. This will give options and keeps the lever travel shorter as the bigger slave has the negative side effect of increasing the travel on the lever. This to keep the travelclose to stock and the piston design was the key for choosing K-Factory over Oberon that has whopping 38mm piston. That is way too much in my opinion but if you are only changing the slave then maybe but I think even so I would go with K-Factory. The quality appears lot better on K-Factory. View detail

Clutch is now much lighter!

When I replaced it with Nisshin's Radial master cylinder, the clutch became much lighter, but it became harder to turn off the clutch when touring long distances due to aging, getting used to the clutch, or losing grip due to age. There was no review of GSX1400, but I decided to buy it because it was highly rated by other companies.
My Motorcycle has a Sprocket cover replaced with Other Brand Product, so it was easy to replace it.
I chose Black because I have a Gold Sprocket cover and I thought Black would look good with Gold, and I was right!
The effect is much lighter, and I used to cut Clutch with three fingers, but now I can cut Quantity.:Even with 2pc it looks like it could run a long distance.
Looking forward to the next Touring! View detail

The Piston was sticking.

P.S..
I forgot to write something in my last post, so I'll add it.
I forgot about it because it's not a problem to worry about so much once the installation is done perfectly.
First of all, this Release was sent in a crimped Vinyl bag, but when I took it out of the bag, the Piston was stuck and would not move! I thought about it for a while, and then I tried to pneumatically pressurize it, but it wouldn't work! Then I sprayed it with CRC. Then I sprayed it with CRC, put on a plastic head that matched the size of the pistons, and used a gold hammer to delicately tap it. Then I put the head of the plastic that fit the size on the head.
Thanks to this, the Wound of the pliers came on before I used it.

Sorry for all the bad reviews, but I'm writing the facts.

If you don't apply Grease etc. when shipping, you should do something. If you don't have a process to apply the Grease, you should do something about it. View detail

You think a Type K is a bad idea for a ZrX1200R?

About 8 years ago, I used KFACTORY's Clutch releaseA?Type and K-FAQ's Sprocket cover, but after 10000km, the Release leaked fluid. The cause is that the rubber ring of the piston in the release is worn out, and the piston interferes with the outside parts and there is a gap.
After that I went back to NORMAL and used the 14R Release.
This time, I ordered kType to change back to Aluminum Cut-out for Sprocket. As a result, I couldn't cut the clutches with Type K even though Type A is just right. However, NORMAL Sprocket cover + Type K can be used.
KFACTORY, what I'm trying to say is that Release and Sprocket cover add up to a very high price! You should display the compatibility exactly.
It's not a matter of just being able to use it.
By the way, the bolt of Release is too short to be attached to KFACTORY's Sprocket cover. This means that KFACTORY has known about it from the beginning, but they didn't disclose it to the public. That's right!
If I knew that, I wouldn't have paid 28,000 for it.

KFACTORY's Axle Slider also had one short bolt and could not be installed at times.

My faith in KFACTORY is gone, which is a shame because the Design Sense is great. View detail

Used for ZX10

I bought it to reduce the burden of operating the clutch and for maintenance.
The ZX10 is not included in the compatible car models (it was mentioned in the manual that came with the car), so there was no guarantee that I could install it, but I took a gamble that it should be common for the same engine.

As far as I checked Piston diameter before purchase, KFACTORY's 36.4mm was the largest.
According to my calculations, the 19mm MASTER should be about 1.18 times more effective than the OEM.

I was able to install it without any trouble just because the Manual said I could.
It is the effect of the important thing, but it became light but not surprisingly, but that was as I imagined, so it was as I expected in a sense.
In my case, I am fully satisfied with the effect of the reduction and the fact that I was able to replace a part that had not been replaced for over 30 years with a new one.

The ZX14OEM (35.7mm) is the best choice, but if you want to get the best effect, this product is the best choice.
I like that it has more color line naps than the competition, and the fact that it comes with a crash washer is also helpful. View detail

At first, when I installed it, I didn't think it was so different from the Clutch, but when I went touring Left I was impressed that my hand is not numb But the price is high View detail

K-Factory slave cylinder on Bandit 1200

Beautiful and functional! I purchased this mostly for looks, but it indeed decreases lever pull. Installation is easy and it comes with fasteners and a bleeder. View detail
