The RIVCO ones are designed to fit the earlier Standard peg models 2004 to 2009 i.e not the 2010 onwards Roadsters with ABS which have a different foot pad and extension bar as do the R3Ts.
There was also the version for 2007 on R3s with factory footboards fitted like the R3 Classic and R3 Classic 'Tourer'. The 'Tourer' was a fully kitted out factory optioned version of the 'Classic'.
Pretty sure they are long out of production but I have Chrome one I tried to fit to my R3R.
Got it from Squaredeals motorcycle clearance in UK I think.
Yep, they still have them 2 years on!
