As they are in business for more than 40 years, you can be sure that they know all ins and outs of clutches. They developed their Carbonite clutch kits specifically for High-Performance applications. This carbon fiber and nitrated-steel clutch set (hence the name "Carbonite") offers an enhanced initial friction value and enhanced lockup. The Carbonite's steel plates get the same special nitrate treatment as the cores from the bonded friction plates, aimed at preventing them from warping. The nitrated steel also cools and lubricates the clutch, improving the overall feel and performance. Carbonite clutch kits can be used wet or dry, but it's really best suited to wet applications. All kits feature an extra friction disc and an extra steel plate for increased torque taking capacity. Fits 1990-1997 Big Twin, 1991-2004 XL Sportster and 1991-2002 Buell 711752 Complete clutch pack, contains 10 externally splined single sided Carbonite frictions, 10 internally splined single sided Carbonite frictions and 1 double sided Carbonite friction Fits 2005 and later XL Sportster & air cooled Buell 789858 Complete clutch pack, contains 8 externally splined single sided Carbonite frictions, 8 internally splined single sided Carbonite frictions and 1 double sided Carbonite friction Barnett has always been number 1 of technology designing innovative clutches to meet the specific demands of street and racing motorcycles. The latest innovations are these Carbon Fiber clutches that provide high static and dynamic friction coefficient for smooth, positive engagement and release. They are designed for use in conjunction with OEM or Barnett steel drive plates. Available as kits that fit like stock, but also as "Extra-Plate" kits for use in High Performance applications. Fits 1991 to present Sportster and 1991-2002 Buell. Extra-Plate kit does not fit XR1200 721921 Performance clutch kit, 8 Barnett Carbon friction discs 721922 High Performance "Extra Plate" kit with 9 Carbon Fiber lined friction discs and 8 steel drive plates for 12% friction area increase 2707 "SERIESK96" KEVLAR CLUTCH KITS Barnett is leading the wave of the future with the development of these smooth working, long lasting "Series-K96 Kevlar" clutches. Test results show that Barnett's asbestos free "Series-K96" clutches lasted 12 times longer than asbestos clutches and 3 times longer than semi-metallic. All the advantages from the new "Series-K96 Kevlar" material and more. Barnett has developed these kits for performance motors and those who need extra clutch control. The "trick" is to increase the friction surface by adding an extra friction and drive plate. And when there is space enough, Barnett has even increased the friction surface per plate as well. "Extra-Plate" clutch kits install like a stock clutch and include all required parts. Fits 1991 to present XL Sportster & 1991-2002 Buell.
