For the WIKI as I read this thread in whole like 9 years later....

I was all set on ordering NV125 parts. Turns out I had the LWX500.
The chain is the same. I did order from Cobra since I did call them and ask what are your thoughts on this magnetic strip. We had a conversation, they earned the business. The chain can be found for 25% less elsewhere...

The big difference was the seals for the LWX500. Buy the seals for this at your favorite OE dealer. It is cheaper.
