Hi Vincent. What engine and bike are you considering installing these cams in, what is your intended use of the bike, and what other modifications are you planning to do to support the cams? This all factors into a cam choice.

Good questions here; I had a built 103 with a 260 cam. The only two good things about the build were the sound of the idle and the performance above 4k rpm. Other than that, it was kind of an unimpressive cam.
I think there's a bike around locally with a 120r and a 260 cam - also kind of lackluster. Again, cool idle sound but I'm not sure it's really the best cam in it's family.
My 117 kit came with a 259E cam. It's a little smoother, more well behaved down low and has a little quieter valve train. Not much though.
I don't think that helps.
I can say with confidence that I wouldn't swap either into a 110 without other supporting mods.
