[forged steel FRONT]

■Feature 1: Chromium molybdenum steel casting material is used as material
The front sprocket receives the engine power directly, it should be strong enough.
Sunstar uses chromium molybdenum steel forging to increase the strength of this product.
*Some of them are not forged.

■Feature 2: Extensive offset lineup
Offsetting the chain line is essential when widening the rear wheel and installing larger tires.
The offset sprocket is a necessity to cope with this.
Sunstar offers a wide range of offset dimensions.
High precision Sunstar sprockets for advanced undercarriage customization.

■Feature 3: Convertible front sprocket for race use
Special sprocket for converting the chain size, which is common in racing vehicles.
This is a lightweight sprocket with lightweight holes drilled mainly for super sports vehicles.

Sprocket exchange with 525Conversion

Purchased for Chainfor Conversion.
It is a product that looks and feels very high performance.
The exchange is quite Large strange.
Side Cowl Left top, Left bottom, remove Computer base like PGM, remove Shift bar, Drain hose of some kind.
Two pieces were moved, and the Sprocket cover was removed to finally show them off.
I did not remove Coupler from Computer. I was afraid that an error might occur.
The cooling hose is in the way, but the hose can be replaced without removing the Sprocket.
It was my first time and it took less than two hours.
It is by far the lightest, and I am sure it will be good.
The exchange was Large strange and I forgot to take a picture after the exchange! Too bad...

Required to wear 17in.

(This part is required when replacing the rear wheel with a 17in.
I have no problem at all with the product, and it is the only choice I have.
I think the most Large strange way to replace it is to remove the Bolt from the Sprocket part.
I think the price is a little high.

Looks well made.

I put it on my VTVT250 SPADA and compared to the AFAM that I used for 20,000 km, I think the jingling sound is a little less.
Since it is an OEM-adopted Manufacturer, it is well made.
