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
It is the best sproket!
This is insane ! Its weight is really light! If u compare this with oem sprocket, u may feel what i told. And this looks so cool so my bike looks more beautiful View detail
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!

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.

Good texture and cool colors!
I really liked the colors anyway!
The downside is that it took quite a few days to arrive,

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.

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.

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.

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.

Functional beauty!
I replaced the ISADriven Sprocket with the Driven Sprocket as a press-up, and I could feel the direct response to the throttle operation. As a conclusion, the Driven Sprocket was not able to feel the goodness at all when riding after the replacement. However, I am satisfied with the beauty of the machining and the high quality of the parts themselves. By the way, for wr250x, there is no hole for weight reduction, but the reverse side was cut out by cutting. View detail
