It is durable because it is made of steel, and while aluminum will wear out quickly, this product will last more than twice as long.
It doesn't look bad, and if you are not very particular, I think this will be enough.

**Design varies depending on the number of teeth, size and models.
*520 conversion size is available for DT125R / 200R, DT230 LANZA, TT250R RAID, KDX125SR, SX125R, JEBEL 125, DF125 and DR125.The stock model is 428, so please make sure you buy the right one.
*DT200WR, TT250R, WR250R / X, KLX125 / D-TRACKER125 require a taper sprocket bolt separately.
*If you want to change the size of your sprocket, you will need the correct chain for that size.
*Even if the number of teeth is selectable, it does not mean that all the parts can be installed.It may interfere with the vehicle body or other parts, or cause problems.If it is unavoidable to increase the number of teeth in the rear, reduce the number of teeth in the front so that the balance between the front and rear can be achieved.

* The image is only for reference. The image shown may differ from the actual product.
The durability is incomparable to that of aluminum by optimizing the material and heat treatment.
The design of the steel sprocket is made by high-precision laser cutting, and it has an excellent strength balance and is about 30% lighter than a standard steel sprocket.
