Stage 2 SNYPR Clutch Kit for Polaris Patriot 650 (Short Track Sleds) // SKU: 06-37-309
⚙️ REQUIRED KIT SELECTIONS: Please configure your kit options using the dropdown menus above:
-
Secondary Clutch Helix Style:
- Standard TSS-4 Helix (SKU: 05-TSS-4): Precision-machined dual-cut billet helix engineered for aggressive shift-out and instantaneous backshift response on high-speed trail systems.
- Lightweight TSS-4C Helix (SKU: 05-TSS-4C): Precision CNC-pocketed design that sheds almost 20% (nearly 18%) of rotational mass to reduce drivetrain inertia and provide faster throttle pickup.
-
Secondary Spring Anti-Binding Hardware:
- Smooth Shift Teflon Washers: Maintenance-free, budget-friendly teflon washers that isolate spring rotation and eliminate binding under compression.
- TSS-04 Secondary Roller Bearing: Premium needle-bearing assembly delivering near-zero rotational friction under heavy loads for ultra-fast backshifting and cooler clutch operation.
SKU: 06-37-309
Primary Application: Polaris Indy, VR1, XCR, Pro-S, Pro-X, and Switchback Assault 650 models equipped with 1.25" to 1.6" lug tracks.
Transform the power delivery of your short track Polaris Patriot 650 with the Bikeman Performance Stage 2 SNYPR Short Track Clutch Kit. While stock Patriot 650 clutching is decent, Bikeman dyno and field testing proved this engine demands to be loaded harder to unlock its true potential. This kit optimizes primary and secondary clutching to eliminate lag, transfer more horsepower to the track, and deliver explosive corner-to-corner acceleration.
The standout feature of this short track kit is its lightning-fast backshift. When you chop the throttle into a sharp bend and hit it on exit, power is instantly on tap with zero hesitation. Featuring fully adjustable SNYPR primary weights, your choice of standard or lightweight short track helix profiles, and secondary anti-binding hardware, this kit allows you to easily fine-tune shift RPM for stock setups, aftermarket pipes, or altered gearing across various elevations.
Key Performance Features
- Lightning-Quick Backshift: Delivers instant belt recovery and throttle response when cycling the throttle through aggressive cornering and trail turns.
- Rotational Mass Reduction Option: Choose the lightweight TSS-4C helix to cut secondary rotating weight by almost 20% for razor-sharp throttle snap out of turns.
- Hard-Loading Acceleration Profile: Optimizes force curves to keep the Patriot 650 engine locked in its peak powerband for maximum acceleration and top-end speed.
- On-The-Fly Adjustable Weights: Infinitely tunable using magnets, set screws, and tungsten slugs right through the clutch inspection hole—no need to remove the clutch cover or main spring.
- Short Track Custom Helix: Engineered specifically for short track gear ratios, lower lug heights (1.25"–1.6"), and short track chassis resistance profiles.
- Customizable Anti-Binding Performance: Choose between low-maintenance Teflon Washers or high-performance TSS-04 Needle Roller Bearings to eliminate secondary spring bind, smooth out upshifts, and lower belt heat.
- Optimized Engagement: Provides slightly higher engagement RPM over stock for crisp initial launches without aggressive track spin.
Critical Fitment & Roller Compatibility Note
⚠️ IMPORTANT OEM CLUTCH ROLLER FITMENT NOTE: Both the standard and lightweight secondary helix options in this kit require small secondary clutch rollers for bind-free operation.
Polaris introduced a larger OEM secondary roller on select models beginning in 2021. These larger factory rollers are NOT compatible with this helix profile. This kit includes our Small Secondary Clutch Rollers (TP-460079K) to ensure seamless conversion, bind-free helix operation, and optimal performance on all 2021+ models.
Kit Components Included
- SNYPR Magnetic Adjustable Primary Weights (SKU: 05-HAW-5889): Includes set screws, magnetic tuning discs, and tungsten slugs for fine-tuning.
- Primary Drive Clutch Spring 140-320 (SKU: 05-140-320)
- Secondary Driven Clutch Spring 140-220 (SKU: 05-140-220)
- Secondary Clutch Helix Choice (Select Above):
- Small Secondary Clutch Rollers (SKU: TP-460079K): Mandatory small-diameter rollers for bind-free dual-cut helix clearance.
- Secondary Anti-Binding Selection (Select Above):
- Comprehensive Clutch Setup Guide: Baseline calibrations for stock, piped, and modified setups.
