Not compatible with YZF-R1 15-.

YZF-R1 Year:98-21, but not compatible with 2017. Probably not compatible from 15 years.
It is a strange conformity notation if you think about it, but I bought it without realizing it.
To begin with, the YZF-R1 (2015-) is a 5-hole, but this product is a 6-hole.

Please be aware that if you are from 2015 or later. View detail

Driven Sprocket Replacement

The Driven Sprocket had significant wear and had to be replaced.
I searched for the same item and found that SUNSTAR has discontinued (?) the same part number. I found the same part number in SUNSTAR.
What SUNSTAR has is Quantity with Driven Sprocket:Set product with only the OEM Standard 17T-44 gun combination.
After searching for a replacement, I finally found ISA's 43-dot.

The reason for the change in the number of Sprocket's Ding, in the Number of teeth on the OEM.
? The response is peaky and there are situations where it is difficult to handle.
Tight HairpinCorner cannot be held back in 2nd gear, and feels Torque deficient in 3rd gear.

By changing the number of pins, the Tight HairpinCorner can be used in either 2nd or 3rd gear, making it easier to handle.
Therefore, he chose ISA to maintain that setting.


However, it takes about two months for delivery, which is unavoidable due to the order-made nature of the product.
I placed an order on 3/9 and received emails on 3/10, 3/14, and 3/15 informing me that the order was being arranged.
No progress report for about a month after that. (This is not good.)
On 4/17, I received an email confirming that AFAM's Driven Sprocket, which I ordered at the same time, was either continued or cancelled because it was out of stock.
There was no alternative and we decided to continue ordering.

I received an email on 4/18 with a shipping notice (what the heck? This!!!!!!!!!!!!!!!!!!!!!!!!!!)

Arrived 4/19. (It took 40 days from order to arrival.)

4/27 installed at my favorite Motorcycle shop.
While replacing the Sprocket, we also decided to replace the Bearing, Dust Seal, and WheelDamper.
I thought about replacing it myself, but there was no SST and I gave up.


Impressions after the replacement are the same as before (laugh), easy to handle. View detail

Very light.

[How is it used?
For speed in Circuit and weight reduction under Spring.
Was the one you received as per Image?
Yes.
Was the installation difficult?
If you can remove the rear wheel, it is nothing.
How was your experience with it?
First, I was surprised when I held it.
It is so light that one wonders if this is not a Sprocket but a cookie.
I have been using Steel's Sprocket until now, but after replacing it, it clearly runs Quickly.
We replaced various suspension parts at the same time, but I think we had the most exchanges.
The weight under the Spring is Large. Especially for rotating parts, GYRO effect also works, so even a small weight reduction may be effective.
[Included Parts:were they on?
One Sticker.
[Was there anything that disappointed you?
None

XJR1300C's 520 for Conversion

[How is it used?
I introduced it to XJR1300C which I use for Touring and Main for city riding.
The OEM is 530 Size, but we have Converted it to 530 this time to save weight as well.
By the way, Front is SUNSTAR's Item number:395-18 was used.

Was the one you received as per Image?
As per Image, a beautifully processed product.
They say it is more accurate than SUNSTAR. I don't think it would make that much difference if you put it on a public road vehicle.
The reason why I chose ISA this time after always using SUNSTAR is because the anodized color of the decidedlySprocket is chic and matches the car body. (LOL).
I decided against SUNSTAR this time because SprocketChampagne gold is a bit too conspicuous for my vehicle.
And ISA's Sprocket was a nice Anodized Color as shown in the Image.

Was the installation difficult?
Nothing difficult, just loosen and tighten 6 Nuts.
The size of the nut is M14. When tightening the nut, be sure to tighten it diagonally and twice.
The service manual also says so.

How was your experience with it?
I have driven about 100 kilometers with no problems.
Anodized is also not worn out. The 50μm thick hard Anodized may be better than SUNSTAR's Anodized.

[Included Parts:were they on?
A single Large tight ISA Sticker was included.

[Was there anything that disappointed you?
It's not in the product itself, but the way Sticker is attached is a little too messy!
ISA... maybe you didn't have the Space to put it up.
I'm sure I could have put it up better! View detail
