For reasons unknown, Triumph had a difference in the frame at JBQ's mounting point for the 2011 R3 Roadster. The mounting bracket for the tube that supports the right foot peg has a very thick "spacer" as built into the mount.
The R3 JBQ will not fit this model / year.
2009 and earlier is OK; 2012 and later is OK; 2010 unknown.
