Components:
Drive clutch (primary), driven clutch (secondary), drive belt, chaincase (for final drive).
Gear Ratios:
CVT system provides infinite ratios within its operating range; specific gear reduction ratios for the chaincase would be detailed in the manual.
Clutch Adjustment:
Manual will detail primary and secondary clutch calibration, belt tension, and sheave alignment.
Chaincase Oil Type:
API GL-4 or GL-5 gear oil, specific viscosity (e.g., 75W-90 or 80W-90) as per manual.
Chaincase Oil Capacity:
Typically around 8-12 oz (235-355 ml), check manual for exact capacity.
Length:
Approx. 90-100 inches (228-254 cm) - varies by specific model.
Width:
Approx. 35-40 inches (89-102 cm) - varies by specific model.

Dry Weight:
Approx. 350-450 lbs (159-204 kg) - varies by specific model and engine.
Gross Vehicle Weight Rating:
Not typically specified as a GVWR in the same way as cars, but relates to rider and cargo capacity.
Crash Test Results:
N/A (Snowmobiles are not subjected to automotive crash testing standards).
Braking System:
Hydraulic disc brake system on the drive clutch or a brake caliper acting on the jackshaft/drive axle.
Throttle Control:
Thumb throttle with return spring mechanism.
Kill Switch:
Emergency engine stop switch, often with a tether.
Lighting:
Headlight, taillight, brake light (if equipped).
Oil Change Chaincase:
Every 100-150 hours of operation or annually. Check manual for exact interval and procedure.
Spark Plug Replacement:
As recommended, typically every 2,500-5,000 miles or annually, depending on usage and plug type. Consult manual for specific recommendations.
Belt Inspection:
Inspect drive belt for wear, cracks, and proper tension at the beginning of each season and periodically during use.
Clutch Maintenance:
Annual inspection and cleaning of primary and secondary clutches, checking for worn buttons, rollers, and springs.
2 Stroke Oil Type:
Specific 2-stroke oil injection fluid or pre-mix, meeting Polaris recommendations or industry standards for air-cooled 2-stroke engines (e.g., TC-W3 certified oil, though specific automotive 2-stroke oil is often preferred).
Coolant Type:
Not applicable (air-cooled engine).
Clutch Wear:
Worn clutch components (weights, rollers, bushings, belt) leading to poor performance, slippage, or engagement issues.
Carburetor Icing:
