My first bike had a chain and it seemed to always need to be cleaned and lubed. I was just using "chain wax". It was part of the reason I decided for the NT instead of other bikes. I wanted a touring bike with a shaft. As many here know, I purchased a DR650. It has been incredibly easy to keep the chain lubed and clean. I attribute this to changing my routine. I discovered Dupont teflon in the blue can.

This stuff makes chain maint. about as easy as it can be. If your just riding asphalt then it doesn't seem to get dirty. When riding gravel and dirt roads the dirt and gravel dust just doesn't seem to stick to this teflon/silicone stuff. On my big trip this past summer, I only cleaned the chain every 3-4 days of street riding. At first I was worried I wasn't cleaning enough, but it hasn't shown any issues or wear. The chain and sprockets are the original ones with almost 10,000 miles and I don't think I will need to replace them anytime soon.
So I simply have not found touring with a chain a problem. It wasn't even an issue over 2.5 weeks of travel and 5300miles. I understand the prefernce for a shaft in a bike like the NT, but please, lets not exagerate the chain maintenace issue. Complaining about having to spray a little lube on a chain every so often is kind of a first world problem.
Having said that, I do find it interesting that Honda has not tried belt drive in more bikes. If HD, BMW, and others can do it..... I think belt drive is a great choice for street bikes.
