Power and Speed Kit for Polaris Patriot 850 (Short Track Sleds) // SKU: 13-310-PS-ST

Primary Application: Polaris Indy, VR1, XCR, Pro-S, Pro-X, and Switchback Assault models equipped with 1.25" to 1.6" lug tracks.

Transform the performance of your short track Polaris Patriot 850 with the Bikeman Performance Power and Speed Kit. By pairing our industry-leading ECU digital tuning calibrations directly with our Stage 2 SNYPR Short Track Clutching package, this unified kit eliminates factory engine lag, unlocks broad mid-range pull, and delivers explosive corner-to-corner acceleration.

Stock engine maps and clutching calibrations are engineered for mass-market compromises, leaving valuable horsepower on the table and upshifting too conservatively. The Power and Speed Kit re-calibrates fuel, timing, and secondary backshift as a complete system—keeping your Patriot 850 pinned directly in its peak powerband while lowering operating temperatures and extending belt life.

1. Choose Your Digital Tuning Platform

Select your preferred tuning delivery method from the dropdown options on this page to load Bikeman's dyno-proven Patriot 850 performance calibration:

  • Option A: Torque Link Pro (Mobile Smartphone Tuning): The ultimate next-generation mobile tuning platform. Flash your Patriot 850 directly from your Apple or Android smartphone via Bluetooth/Wi-Fi with zero computer required. Grants full access to tune libraries, real-time diagnostic engine logging, and fault code clearing trailside.
    *REQUIRED POLARIS HARDWARE NOTE:* Flashing Polaris snowmobile ECUs via Torque Link requires both the Torque Link Data Cable AND the Polaris ECU Power Cable for proper communication and voltage supply during the flash process.

  • Option B: ECU Hard Flash (Send-In Bench Service): The seamless "set-it-and-forget-it" setup. Simply remove your ECU and mail it directly to our facility. Bikeman calibration specialists will flash our custom tune file directly to your module, clone your vehicle data, and ship it right back ready to plug in and ride.

Every Power and Speed Kit includes our complete, fully matched Stage 2 SNYPR Short Track Clutch Kit (SKU: 06-37-301):

Key Performance Features

  • Optimized Powerband Delivery: Refined ECU calibrations deliver crisp off-idle throttle response, eliminate low-end hesitation, and hold peak horsepower through full-throttle runs.

  • Lightning-Quick Trail Backshift: Instantly drops into the ideal drive ratio when chopping the throttle into turns, putting maximum power back on tap the moment you re-engage.

  • On-The-Fly Adjustable Weights: Infinitely tuneable using magnets and tungsten slugs through the side panel to easily dial in shift RPM for altitude changes or exhaust mods.

  • Short Track Optimized Secondary Ramp: Features custom multi-angle helix geometry designed specifically for hard-pack trails, crossover drag, and 1.25"–1.6" track lugs.

  • Cooler Operating Temperatures: Smooth-shift Teflon washers reduce internal spring binding and friction, lowering clutch temperatures and extending drive belt life.
