Very nice!

Good price and good quality!

Good sprockets for the high gearing setup.

Perfect fit

Good product, excellent customer service

Awesome product for a good price.

Sprocket looks & performs good as any on the market! The sprocket fit well. I've put 6-8 hours of ride time on it & I have zero issues with the sprocket!

Highly recommended them

Fit my 74 perfectly and since my bike is now white and black and gold, this black sprocket looks great with a gold chain.

Cheap, solid. Definitely will be ordering again when this one kicks the bucket. '07 KX250F

Best part about it is the cheap price for a product that lasts a very long time. I had used an aluminum one previously and it lasted for about 2 months. I will easily go the whole year with this sprocket.
