Thats a bit more difficult. Don't have any experience with sliders, though that wil change soon. I'm going with the ones made by Cyclecat. Heard lots of good stuff about their products in general, if not specifically about the sliders. Again, Motowheels is a good source, I believe.
Oh, and no the Enzo ain't mine. Just a good picture I took at Ducati Day Daytona in '04.
