I started riding my new Ninja 250 I bought this bike to start riding my SL and to advance my setting in Circuit riding.
We are still in the first stage of the project. This is the first stage of the project, and we have not yet decided on the number of dong, so we need to prepare a number of dong.
Therefore, I bought Steel to lower the unit price per piece.
I don't worry about the accuracy, etc., because it is a reliable brand, and I don't feel any problems with Level.
It's steel, so it's heavy.
To get to the bottom of it, Material:It will be Aluminum, but I believe that is only after the Setting is decided in a particular Course.
If you have plenty of gold, you can use aluminum.
I'm happy with the cost of the Steel because I don't need to push it that far since I consider SL as a practice bike and don't plan to compete in races.
Also, steel is more durable.
For public road vehicles, Steel is the choice as long as LineUp is available.
I like SUNSTAR's Steel because it looks a little better than the OEM.

[Previous models reviving and evolving REAR STEEL]
■Feature 1: For those who care about superior durability and looks
The material is carbon steel (S45C) which is particular about hardness and durability.
It is designed to match the standard look of old vehicles.
■Feature 2: Considering not only looks and durability but also performance improvement
The stock chain size for vintage models is 630, but for modern chain performance, 530 is sufficient.
Therefore, the chain size is only converted to 530 size to reduce the weight while maintaining the same durability not only in terms of design but also in terms of performance.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.

Z900rs 520 chain conversion 42, 43, 44 tooth?
My 3rd Sunstar sprocket. Stock 525 chain has 15 42 tooth gearing. Not happy with power delivery so tried 520 chain with15 43. Still needed a bit more in 3rd, so I installed 15 44. Now where talking. That is the stock gearing on its Z900 brother. I also installed the Z900 complete motor into my Z900RS with high compression heag gasket. With 130bhp and 44 tooth rear sprocket It is an absolutely wicked retro now :)
