I definitely had to play the spacer game to get mine to fit without rubbing the plastics. I also had to flip the brake linkage to the outside of the brake lever to get it to fit without seriously rubbing the body work. I managed to get things to where only the shifter linkage rubs ever so slightly. I would have thought a rear set designed for a specific bike, would not have fit issues.
I also find the lever arms to be way too thin, if I start getting a little aggressive on the shifting, I can feel the lever twisting a little. I looked down at one point and saw it deflecting. This issue might be aggravated by the fact the linkages are not 100% in line with the lever (because of the body clearance arrangement), or it could be due to the fact I couldn't get the peg screw on that side to the specified torque (26ft-lb), I haven't taken the peg off yet, but it feels like the rear nut is stripping its seat.
I wanted to put up a full post of the pros and cons I have seen so far, but I leave for vacation tomorrow. I really love the design of the Speedymoto set, they look awesome on the bike, and the shifting is so smooth I some times don't even feel the shift, but I'm surprised by some of the glaring cons. The Speedymoto top triple is/was my next purchase for the bike, I hope that works out better.
