Precision Auto ProductsRazor MX500 and MX650 Chain - Heavy Duty 132 Link Drive Chain - #25 Roller Chain 132L - Razor MX500 Electric Drive Chain - MX650 Dirt Bike - Razor SX500 - MiniMoto XRF500

Absolute junk. Installed on mx650. Broke in less than 3 minutes. Did not snap at the connector link. The actual chain broke in the middle.

I just got the chain installed, but there is a huge problem with this chain and it's simply too short. I was forced to rig it up with two bolts on the motor, as I was unable to put the third one in due to its length. I don't expect the chain to last long do to the strain and tension on the chain itself. I don't understand why the manufacturer did not add just a couple links more as there is a tensioner on the bike itself to pull out the slack. I can't recommend this product until the manufacturer adds more length to this product. The only thing I can't comment on is its durability and longevity of the product.

So far it has held up OK but the pins that stick through the links are longer and sharper than the OEM so when they slide past the chain tightener it makes a lot more noise and sounds like it will not hold up..

I have bought two of these for my kids MX500 and the first broke within a few weeks and the second broke in about two minutes. I know it was installed correctly as I have worked construction and do all my own mechanic work since I started driving and never have problems. Junk... The END

As with all the other 1 star reviews the chain was too short, which caused the chain to break immediately. Not made for the Razor MX650. Motor and wheel are in fixed position only chain tensioner can add proper tension so it was not due to an installation issue. Good news is the chain breaking saved me the time of taking everything apart to return the undersized chain
