2011 (only) model year.
This model year has a new secondary clutch and we include new primary / secondary springs and flyweight calibrations.

Sportsman 850 clutch kits can be set up for different terrain and tires sizes/elevations. This means accurate clutch tuning for your situation. Improved acceleration as well as better backshifting as the vehicle comes under load.

Kits include Dalton's patented "Quick Adjust" flyweight system that allows you to add or subtract weight from the flyweights without even removing the flyweights from the drive clutch. This is a great feature for those who run different tires in alternate seasons! The new "Quick Adjust" SP850 flyweights included have a different curvature, and location of mass which allows superior belt grip and RPM control.

• Easy RPM control (can be easily adjusted)
• Stock tires or oversized
• Altitude adjustable
• New custom SP 850 specific flyweight profile
• Set up manual includes set up instructions for above applications
• Year / model specific kits*
