I found that basic info as well, but it is for 2012 models, calls them out as Enduro and Supermoto and specifically reference the 630's.
All non-modified 600cc+ displacement Enduro and Supermoto models come with a one-year/unlimited mileage warranty against manufacturing defects and workmanship that covers parts and labor.
This includes both the TE630 and SMS630 models.
While this may still hold true for the 2013 TR650's, I would like to know for sure what it really is.
24 months would be nice.
