It was time to change. Reliable SUNSTAR
I thought it was time to replace the FrontSprocket, so I replaced it at the same time as the Rear sprocket and Chain.
Although it is not visible, we chose MADE IN SUNSTAR, which is also used by OEMs for peace of mind.
I managed to get the suppression nut off with Impact wrench.
Now I can run comfortably again.

Why is the same number of Ding as OEMs so expensive….
What made you decide to buy?
I have been working on the ZX-6R for 3 years now, and the mileage is about 10,000 km. I thought it was too early to replace them, but since all the parts were available during the spring sale, I decided to replace them.
[How was the installation?
I found information that the Torque of the Engine Sprocket nut fixing the front sprocket was halfway tight, so I loosened the Engine Sprocket nut using an electric Impact wrench from Tirefor Replacement. After that, I tightened the rear brake with the torque wrench at the specified torque of 147Nm, and finally, I bent the washer over the nut using the water pump pliers to prevent it from loosening.
*We are planning to describe this replacement work in our maintenance diary. Please take a look if you like.
How was your experience with it?
At first I was not sure whether to go with 16T or not, but I liked the ride quality of the OEM, so I decided to go with 15T, the same as the OEM. So there was no change between before and after the replacement. The normal specifications list on the product page says 16T, but the 21-year ZX-6R has 15T Front, 43 Rear, 2.866 reduction ratio, and 112 Chain links.

Optimized with Front1Down
[How is it used?
This is an IMPRESSION with 100% Circuit running.
Was the one you received as per Image?
Yes.
This time, we dared to choose 525 without 520Conversion, but even though Steel is the same as OEM, it is MADE IN SUNSTAR. (OEM may be SUNSTAR as well.) is lightweight due to the lack of meat removal and the RubberDamper, which is present on the OEM.
Was the installation difficult?
The shop is in charge of the front replacement, so the process is basically to loosen the axle of the rear wheel, lower the tension of the chain, and then remove and install the front sprocket. The front sprocket nut has a high torque of 140Nm and the OEM is very tight, so it may be difficult to remove the front sprocket without a proper tool.
How was your experience with it?
The OEM YZF-R1/M has a secondary reduction ratio of F16/R41, but even in Circuit, it rarely goes into 6th gear, and most people change it Large. Most people change the ratio to a large one. Unless you want to adapt it to a specific Circuit, it can run in any Circuit to some extent.:As for the Set, I think Front1Down is the best solution, running with the OEM GEAR ratio, In second gear, it's hard to ride at high rpm, and in third gear it's a little heavy." You can drive comfortably in 3rd gear on the Point where you feel like you are in the middle of the road. The appearance does not change at all, but expensive Parts (Exhaust System, Suspension, etc.) I think it is more expensive and outstanding than replacing the

Used for Restore on TW200
It is a little more expensive than other manufacturers, but I trust them.
The one that came with it so far was terrible.
In case of TW200, it is necessary to remove the Left cover to replace the FrontSprocket.
I'll have to buy Packing at the same time.

Front sprocket replacement
Changed Front from 14T to 16T and Rear Sprocket from 48T to 46T.
I thought it would be sluggish at the start because the GEAR ratio was quite low, but I don't mind that much.
It is easy to handle for long touring and city driving.

It works without any problems.
Replaced at the same time as Chain.
After the replacement, I do not notice any change, but it seems to be working fine.
