My Triumph is not a bagger. The tools I carry say Verizon on them. If my chain breaks, Mr. Tow driver can get me with the Harleys, cause I am not going anywhere either.
If your chain breaks you have other worries. 1- Are you still upright and alive. 2- How far down the road is it to walk to get it? 3- Is it in a condition to be broken and master linked? 4- Do you have a full tool kit, breaker, extra links, and a replacement chain?
The new chains are fabulously reliable and long lasting. Belts last 3x longer, are quiet, clean, and no maintenance.
To respectfully disagree, belts are the best technology for the money available today. Many engineers would even rate belt drive well above shafts for performance and economy.

You are correct though that you can break a chain and fix it on the side of the road.
