I've never felt mine slipping. While I tend to ride aggressively I don't generally do any hard launches, since this is a lot to get moving from a dead stop so I try not to abuse it. I know Moe's clutch was slipping when he left Florida to come here. I think he had 60k on it at the time. But he took it easy and made the whole trip without replacing it. Maybe he'll chime in and correct me because I'm sure I got part of that wrong.
