Stock 690 APTC Adler slipper clutches are a fantastic piece of gear for a stock bike. When you start to tinker with the motor and increase the torque to the clutch their design weakness become apparent, they don't grip. A standard 690 with one of our big bore kits and a cam will smoke the clutch out of it in no time flat. This fantastic product from Rekluse is good for about 20% more motor output with no slipping! Rekluse's TorqDrive Clutch Replacement Kit for your 690 is a complete redesign from what you're used to. The TorqDrive increased the number of friction disks over your stock set up affording you more consistent clutch actuation and torque. The kit also includes hardened sleeves that slide onto your stock clutch basket and protects from notching caused by the clutch plates slamming into the clutch hub when the clutch is engaged. This dramatically increases your stock clutch basket life and aids in clutch engagement and disengagement. More Friction Disks = More Torque CapacityTorqDrive technology features thin friction disks and protective basket sleeves. Developed over years of testing in professional racing, the thinner friction disks allow more disks to fit into the clutch, dramatically increasing performance and durability. Tuning options are expanded to maximize power transfer and reduce clutch lever pull effort. Riders feel improved acceleration, drive, and control. Basket Sleeves Eliminate NotchingTo protect and extend the life of the basket, TorqDrive includes steel lining sleeves to eliminate basket wear and notching. Friction Pad Design Aids Oil Flow and Reduces DragThe result is clean disengagement at the lever, improved modulation, and improved clutch control. TorqDrive disks utilize a steel core, while OEM disks use aluminum. When heated, steel expands less than half the amount of aluminum. This means clutch fade is virtually eliminated. Friction Material Provides Superior Grip and DurabilityThrough years of research and testing, we have identified the best friction material for motorcycle applications considering functionality, grip, and durability. This means our friction material can take more abuse than others before losing performance. We’ve seen up to 4 times the life compared to other clutches.
