1/5

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

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

5/5

Good color.

Used on ZX-10R/2019 OEM marque, not compatible but it worked normally.
The combination with the gold chain gives it a nice accent with a slight bronze tinge.
It weighs only about 300g, compared to about 725g for the OEM39T.
The 10R was very careful to start due to the low idling, but after the replacement, the Torque feeling increased due to the change in the number of cylinders, and it became easier to handle.
The design is different from the product image, with two small holes between the Large holes.

Chain increased from 114L to 116L due to change in Ding number.

The durability has not yet been evaluated as it has only been replaced for a short time. View detail

High-performance Sprocket that combines performance and strength used by Works

[How is it used?
He mainly rides around town and occasionally goes on touring trips.

How was your experience with it?
Since the 520Conversion is a 520Conversion from the 525, the Chain is also lighter, and rolling resistance seems to have been dramatically reduced.

How did it compare to other products?
Other companies' products have NameValue and bright colors, and many people use them, but if they are too flashy, isa is Recommendation.
The most important factors for Sprocket are low friction, strength, and light weight, since it is the part that rotates. This is proven by the fact that Works uses it.

Note that the number of pieces differs depending on the Spec. of the reimportation. The North American Spec. is 43.

[ITEMS TO BUY TOGETHER
Simultaneous exchange with 520 Chain.
The Japanese specification is 530, so making it 520 will make it much lighter. View detail

Sprocket is an ISA

I've used ISA Sprocket on other cars and it seems to hold up really well. It looks exactly the same as it did when it was new for a while after I started using it.
I think there are a lot of people around who use it for Motocross.
There is a wide range of settings for the number of pages, and I think there is enough for any scene. View detail

High durability Sprocket without being too flashy

It installs it in SEROW250 when the running distance of the paved road running center is about 30,000km.
I was curious about the difference between the OEM Sprocket with and without the RubberDamper, so I kept the FSprocket and Chain from new and replaced the Rear Sprocket with a 48 ISA Sprocket which has the same number of teeth as the OEM.
If you replace the SEROW250 by yourself, you should pay attention to the tightening torque with 6 Stud bolts and Nut.

As for the Damper, it is the difference by the existence of this Parts which is small of the capacity, but when I sharpened the nerve, I felt that the direct feeling of the beginning of opening Axel went up, but at the time of the embrasure by AxelOff and Downshift, I did not understand the difference almost.
Personally, I don't think I could do without it.
I didn't notice any difference in weight savings to me.
I replaced it almost 20,000km after I installed it, but I was able to still use it because I replaced it at the end of the life of the Chain which ran 50,000km.

For an Aluminum Sprocket, it is quite durable and has a beautiful finish and high quality.
If your goal is to reduce weight and you don't want to use SprocketAdapter, this is the one choice.

redundancy
I measured after removal and the ISA tooth thickness is 7.3mm and the collar is 10.5mm, the OEM tooth is 7mm and the collar is 9.6mm (The thickness that hits the collar of DRC SprocketAdapter is 10.0mm) 。
I think the OEM has a RubberDamper so the center part where the Bolt goes moves very slightly.
Damper can be bought individually. (About $1,700 × 6 pieces!) It's not going to be easy to move.
The center of the thickness of the teeth is 14.15mm and 13.1mm respectively, which is about 1mm difference.
I did not feel any discomfort when I turned the tire by hand, and there was no abnormal wear on the teeth, so both may be the correct answer, but why? View detail

light (i.e. not heavy)

Got it cheaper at a physical store, so I traded it!

I thought the product was light in my hands, and when I held the NORMAL that I replaced it with, I felt the lightness even more.

The drive unit is lighter, so it may be lighter to drive.

I've only done a little riding around the neighborhood, I'd love to go touring somewhere. View detail

4/5

Good texture.

This is for Motocross course only.
Shot peening has been applied to the surface treatment.
It would be nice if the durability was a little better.
The shape and the three-dimensional pattern are high quality.

I'm using SUNSTAR's Aluminum Sprocket.
It was worn out and had to be replaced.
At some point the hub mounting bolt nut started to come loose.
I've had to retighten them at least twice in the morning and afternoon for each day of driving.
I'm sure the direct cause is due to vibration.
It was unclear why it had suddenly started happening.
I thought the wear on the teeth could use a little more work.
I was wondering if the looseness could possibly be caused by wear? So I thought.
Since SUNSTAR was discontinued, I replaced it.
I chose this one because of its reputation for accuracy.
As a result, the looseness is gone.
Has wear changed the resonance point of the vibration, or is it the performance of the ISA Sprocket?
I can't judge, but I'm glad anyway.
I'm running low on options, so if it's not a problem, I'll choose this one next time around. View detail
