【KOHKEN (KOHKEN DENKA)】Radial Mount Off-set Collar (1 Set Of 4pcs.) Review

For GSX1300R HAYABUSA

[How is it used?
This has become necessary along with the replacement of the Caliper on the GSX1300R HAYABUSA.
I don't need OEMCaliper, but this RADIAL CALIPER needs a color.

At first I wasn't sure of the thickness of the color, so I tried different colors.
For SEA BASSOEMFront fork, 15mm is just right, not 18mm.

Was the one you received as per Image?

Compact, good quality.
The price is inexpensive for the solid quality of the product itself, and I think 6,600 yen for four is a bargain.
Four products from other Manufacturers cost more than 10,000 yen.

Was the installation difficult?
It is not difficult because it only needs to be placed between Caliper and Fork.

How was your experience with it?
Exactly.

[Included Parts:were they on?
There is none
Instruction Manual is not required, so you will know it when you see it.

[Was there anything that disappointed you?
I would like to see the compatible Size for each car model listed.

I tried various sizes, but I had to buy several sizes and try them one by one by myself because I couldn't find out what millimeter is the most appropriate on the Net. After all, 18mm is too high and 1/3 of Rotor is not pinched.

13mm is too low and Rotor will not be able to turn.
15mm fits perfectly View detail

To install a 320mm disc on a '21 ZX-6R!

From the first play with the Brakes in 2023 to the Master Cylinder, Brake line, Caliper, and Clutch replacement, it was finished. The only thing left was the disc, and I had a long-sought brembo at the summer We-BigSale.:I purchased a Floating Disc. 310mm OEMDisk size would have been fine with the 9mm PLOTOffset collar I have been using, but I purchased a 320mm…OEMSizeOver, so the Offset collar was also changed.
To select an offset collar, I borrowed an 11mm offset collar from a friend and measured it. However, when I selected 14mm, the measurement result showed that the pad contact surface slightly protruded from the disc. Therefore, we decided that 13mm Offset collar by KOKEN would be the best choice! I decided to go with the 13mm Offset collar by KOKEN. The color of the collar is black, and while PLOT's Offset collar is matte black, Koken's is glossy black. The OEM dwell pin fits perfectly, as expected of made in Japan quality. The only complaint I have is the cushioning material. It is a thin and thin Nylon cushioning material and I don't notice it even if it falls on the floor or table. The only complaint I have is that the thin, dusty Nylon cushioning material is too thin to notice if it falls on the floor or table. (Chuckles) View detail

Is this what you got? Too bad.

The color is totally different from the sample. I was aware of the slight error since it is a picture, but the color is totally different.
The package is listed as titaniumium gold, but the actual color is somewhere between gold and orange.
In addition, one of them is obviously a different color, so much so that I think it's the wrong Material. 。 I wonder if the electrolysis process took too long during anodizing. This product is not suitable for shops that charge for labor.
Since the work is not progressing, we will use it temporarily this time for now. View detail

Just right for an adjustment.

Bought this because I needed it for a Caliper replacement.
It's not a strength problem, so you can use it.

It's hard to get a better impression than that with a product like this. View detail

It is the best texture.

In attaching brembo to H2SXSE, it is absolutely necessary.
I had trouble wondering whether it was 8 mm or 10 mm, but made it the same as 10 mm for Z 900 RS.
Installation is easy!
Because it is uneven, it will be worn out OEM Color.
Mounting Bolt was easy to replace as it was OK with OEM diversion. View detail
