I have the rivco risers on my 2014 Roadster.
They made a huge difference. Originally I thought I would want more pullback but after riding the bike on a 6000 Km trip to cape breton (which I recommend by the way) I wouldn't want it any further back or up. With the risers the wrist angle is just right and still gives me the right angle to lean in and ride aggressively with great control. If I pulled it back even 2 more inches it would be harder to control on tight switchbacks.
Just my thought.
The installation on the 2014 was ok but don't beleive the instructions: They say you don't need to disconnect the breakline but they lie, because of how things are made re-routing the break-line was needed. I don't have dealertool to bleed the ABS so I just paid my dealership $50 to move the breakline and I did the rest myself. Took me about and hour end to end, with an extra set of hands to help.
To be honest the cables are a little tight at a hard left. I will be replaceing them but it got me through the season with no issue.
Overall .... best $200 I ever spent, combined with the corbin seat and backrest it made a huge difference.
