AlveyTech 40 41 420 Chain Review

Holes not aligned. Very dissatisfied with the quality of the product received, the layout is not centered, probably not balanced. I then had to pay the shipping cost to return the defective item that I received. A friend ordered the same product and had the same problem

The only problem is that they are not often in stock. The perfect upgrade for the Coleman CT200U, CT200U-EX and BT200X mini bikes when you also fit a torque converter and maybe even an 8 or 9 tooth pinion. Also, they used to be black, but now they are silver.

This sprocket is not concentric which results in the chain having very tight and very slack areas during one revolution. Bought about a month ago, installed over the weekend. The chain is brand new pre-stretched and the rear wheel and tensioner are perfectly aligned. I'll take it off and send it back. Unfortunately, QC seems to be low for them from start to start.

Baby here. Got this on my Colman ct200uex Baja Warrior and am ordering it for my second ct200uex. My ct200bt has 72 teeth. I found 60 teeth to be the best value for a torque converter pair with upgraded blue clutch springs and yellow driven pulley springs. Wheelies for a few days and still 48mph. It's not the heaviest and strongest brand in my opinion, but the price is amazing. It has withstood my heavily modified 196 and some 212 Predators. It is much easier to install than fixed sprockets.

Perfect for my Coleman BT200x. Even the circuit protection kicked back in. You will need a cutout/spoke sprocket like this one. Avoid the tough ones that are out there. Getting the nuts on the back of the hard ones is very difficult. Spokes make changing sprockets a lot easier (ask me how I know that haha). You need a new chain because the original chain is too short for the large sprocket. Lost a noticeable amount of top speed but gained significant torque. Now it lifts the front wheel when I…
