I sold my KTM 950 Adventure this past winter and bought a new RT. My wife and I put 45k 2up on that thing but only the last 4k on an aftermarket seat. Might still be riding it if not for inattentive 21 yr old who rear ended me. We had a Russell Day-long made and it was superb. But, that is the only experience I have with 2up custom seats. As with heat, shipping, suspension, etc it costs a grand plus. We are not iron-butters anymore so would love to hear from others about their experience with any other brands. The stock seat sucks.
