I have decided to stay with the original size front sprocket to maintain the original pull of the bike. In terms of durability, Sunstar has excellent quality control and fit was excellent. I trust it.

The synergistic effect of high hardness by high level quenching and anti-corrosive treatment that does not deteriorate the material boasts excellent durability.When carburizing and nitriding heat treatment is applied to steel materials, it is very difficult to maintain high-precision dimensions because of the different expansion and contraction rates.Sunstar applies a special heat treatment process using its own facilities and technology.

Sprocket exchange almost every time I use it. There is no problem. Those thinking of replacing Sprocket think that you can use it without worry.

I changed it together with Rear exchange.
I changed the Rear wheel to 0 Offset so I had to flip the Front so I exchanged it as soon as I removed it.
Installation's Nut is terrible and hard.
It is not something that can be relaxed manually, so we recommend exchanging it at Impact store in super BigTorque.

Beware has play on main output shaft
My old sprocket has zero play, Sunstar has movement on the splines. Splines over time will be destroyed if installed. Bought OEM to avoid another bad purchase. Also bought a brand new main output shaft for future engine overhaul, same result (play on splines)
