There has been lots of talk about these 2 as well as some imported stuff from Japan. The Japan stuff has more pieces, not just upper lower, but removable smaller pieces, which is not my bag. The Catalyst and hotbodies are both great sets. The catalyst is a little smoother and rounded in the details, the Hotbodies is a little more crisp, so whichever style you like. The fit and finish are excellent with both. I live in San Diego so Hotbodies is local to me I've worked with them for a few years on little projects. After Catalyst and Hotbodies both released their sets and I rode the bike with the basic bodywork and stock seat, I helped Hotbodies design a separate piece that is a tank cover and incorporates a taller seat than stock for track riding/racing. When combined with lower clipons and higher rearsets, it really transforms the feel of the bike from a beginner street bike to a supersport race bike by completely changing the riding eronomics. So I use and sell the Hotbodies simpy because of the race seat, it makes all the difference.
edit: Also, I have a friend who raced an R25 for Factory Yamaha in Asia last year and they also run a taller race seat very similar to the Hotbodies one.
