The sprocket is well made, after putting it on my moped its speed increased. I have done 500km and see no complaints so I am able to recommend this product.

Sprocket purchased to replace from 13z to 15z. Workmanship quality as it is a teething gear (a piece of metal ;)). Fits perfectly, I recommend

I own a 2011 Junak 901. In July 2017 it underwent a light tuning to a larger capacity 125ccm. I ordered a new, larger sprocket to increase top speed and lengthen the gears to make the trip pass more pleasantly. For the price of £10 you get a solidly made, heavy-duty part. I did not expect that for such a price we can get something so well made. Replacement is very easy and quick. My old sprocket already had play from the ground edges of the teeth. This one sits in place perfectly without the slightest movement. I recommend it to everyone!

The sprocket fit perfectly. Well, solidly made. It took me about 5 minutes to install. The bike gained some speed, which is what I had in mind when I bought the sprocket. Recommended for. Zumico GR 200
