Best sprocket I've used

Sunstar works z stainless sprocket held up for over 45 hours on my 250f and still have many hours left when I sold the bike
It's thinner so it's lightweight and teeth are offset to make up the width
Very good sprocket. Ironman is only other that may last longer
Will definitely buy one for my 450 when oem wears down

Bada## set up

the rear sprocket teath are off set to keep the dirt and mud out of it and keep the chain from wiggling around.. just something I didn't know when I bought this kit.. pretty cool

Excellent Drive System

If you are sponsored by a chain and sprocket company that gives you these items, an aluminum sprocket is fine because you don't care about longevity. For the rest of us, this is the ultimate setup. The offset teeth keep the chain and rear sprocket clean from mud, dirt, and other debris while the MXR1 chain is as good as it gets. MotoSport sells this drive system cheaper than anyone else so look no farther. Make sure to order the master-link that matches your chain while you are at it.

Excellent purchase

This drive combo was the perfect setup, chain fit well, rear sprocket was 50% lighter than the stock sprocket on my YZ. The offset teeth kept sand and junk from accumulating. Front sprocket fit like a glove as well. Several riders with me are going to purchase this setup.Did not show any wear after 4 days on the sand.

Great set up

Great sprockets they have held up really well and perform very well. I wish they had different colors, that's about all.

A: Either chain can be ran on your Yamaha YZ250F bike. It is a personal preference as to which style of chain prefer.

A: Yes, the rear sprocket bolts are included with every Sunstar Works Z Sprocket. You would get the bolts with the chain and sprocket kit as well.

A: Yes it does include the sprocket bolts. MotoSport sells this as a kit but each piece is individually packaged in 1 box.
