Very light!
CRF250L (MD47) I installed it in
Compared to the OEM, it is by far the lightest and has a superior texture.
Not flashy Gold, but casual.
I think the Bronze color is for the connoisseur's taste! I think.
Friction has been reduced or Chain movement has been reduced.
Heartwarming and light! I am glad I replaced it.

ONE ONE Rear Sprocket
Purchased because there were no OEM parts available for my 40 year old car. The quality is high and looks good. View detail
It is really cool
It's incredibly light in weight compared to other sprockets. I can definitely feel this and this one in both hands and compare. About a third compared to others. And powerful. Highly recommended! View detail

Fits: SUZUKI GSX-R1000, YAMAHA YZF-R7, YAMAHA YZF-R6, YAMAHA YZF-R1, YAMAHA YZF-R25, YAMAHA YZF-R3
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.

Very good
When you hold it for the first time, it feels very light and firm. In reality, it's almost 1/3 lighter than the previous Asay! View detail

Good looks and good precision!
[How is it used?
Touring
Was the one you received as per Image?
The Gold was just as elegant as I had expected.
I am satisfied with the quality and Large!
Was the installation difficult?
If you have ever removed a Rear tire, it is easy.
If you are concerned, we recommend that you let PRO take care of it.
How was your experience with it?
The low speed is naturally thinner two guns down from OEM, but I personally don't think it's enough to be a concern.

It's an austere color
It was strange that the NORMAL nut had to be removed. I had tightened it with the Torque, so after removing the rear tire, it was impossible to use the hand tool. I used the Impact Driver, but it might have been better to loosen it to some extent before removing the tire. View detail
The GEAR ratio was also decided.
Exhaust System, Air cleaner, Ignition, and Sub computer when
I was running comfortably on an F14R36.
After adding High Camshaft, I thought it would be better to set it to Long, so I set it back to NORMAL and it was doing well.
By the way, I tried F15R36, but as I drive a lot on mountain roads, it was not good for me as the Torque feeling was diminished.

Effect Large at 25R
First of all, the OEM of 25R is iron and 50T, which is ridiculously large, so the effect of aluminum conversion is Large.
It is almost 1 kg lighter, from OEM 1270 g to 375 g.
The color is also good, somewhere between Gold and Bronze, and not too flashy.
It feels light even when turned by hand.
AluminumSprocket is also used on Z900RS, but at 15,000 km, the valleys have decreased a little and the teeth are still there.
If it's a Motorcycle flight or something like that, or if it's about 45 hp and in normal use, you don't have to worry so much about the lifespan.

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.

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.

That was a good purchase
I'm new to ISA.
Design and colors are purchased in shades that are not assertive.
How does it compare to OEM?
Weighs less than half, 0.25 kg compared to OEM's 0.53 kg
The Cut of the groove of the mud play is also Parenthesis good.

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!

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.

People who want to enjoy Touring
In the OEM Sprocket, the engine was set to a higher number than acceleration, so the engine roars when touring or on the highway.
It was not good for me physically and mentally, so I changed to a 40th street and went from high speed to high speed.
Touring and highways have become much easier.
It is lighter and cooler looking than OEM.
Starting in first gear is no problem at all.

ISARear Sprocket
I ordered this for a SprocketSetting for a Circuit run, and since it was made-to-order, I was prepared for the possibility of not getting it in time, but the fast response was more than enough for me. Thank you very much.
Thanks to your help, we were able to improve acceleration and reduce weight.
