The R3T began production in 2008 and has remained relatively unchanged. Since ABS was not available back then, Triumph has spent its development dollors (pounds?) elsewhere. The R3 Roadster was a minor update to the earlier Std and Classic models so while they had the can open, they threw in the ABS functionality. It will most likely be standard on the R3T soon since it costs Triumph more to offer it as an option rather than just putting it on all of them.
