Engine Type:
4-stroke, Single Cylinder, Liquid-Cooled (likely)
Displacement:
Approx. 375cc (Specific engine designation like 'H1' or similar internal Arctic Cat nomenclature might apply, often derived from or shared with Suzuki or Rotax in earlier models).
Bore X Stroke:
Specifics would be in the manual, but typical for this class would be around 80mm x 74mm.
Compression Ratio:
Typically around 9.0:1 to 10.5:1 for this engine class.
Horsepower:
Estimated 25-30 HP (at crankshaft, before drivetrain losses).
Torque:
Estimated 20-25 lb-ft (at crankshaft).
Fuel Delivery:
Carburetor (likely a Mikuni BSR series or similar).
Fuel Type:
Unleaded gasoline (Octane rating specified in manual, typically 87 or higher).
Ignition Type:
CDI (Capacitor Discharge Ignition) with electronic advance.
Cooling Method:
Liquid-cooled via radiator and fan.
Oil Type Recommendation:
Typically SAE 10W-40 or 20W-50 motorcycle/ATV specific oil, meeting API service classification SG or higher (specific grade and quantity in manual).
Type:
Automatic Continuously Variable Transmission (CVT) with engine braking.
Gears:
CVT provides infinite gear ratios. Typically includes High (H), Low (L), Neutral (N), and Reverse (R) selection via a single lever.
Drive System:
Selectable 2WD/4WD with Auto Locking Front Differential. The TRV often features a longer wheelbase for 2-up riding.
Cvt Fluid:
Specific CVT fluid or recommended ATF (Automatic Transmission Fluid) grade per Arctic Cat specifications (e.g., Arctic Cat Extreme Duty Belt Drive Fluid or equivalent). Capacity and type are critical and found in the manual.
Rollover Protection:
Standard ATV design with handlebar and bodywork providing inherent protection; no specific ROPS rating like a UTV.

Common Wear Items:
CVT belt wear, suspension bushings, wheel bearings, brake pads, and starter solenoid are common wear items for ATVs of this age and usage.
Potential Electrical Issues:
Stator failure, CDI unit issues, or wiring harness degradation can occur with age and exposure to elements. Detailed diagnostic procedures are in the manual.
Engine Reliability:
Generally robust engines, but proper maintenance (especially oil changes and air filter care) is crucial to prevent premature wear. Carburetor cleaning might be needed periodically due to fuel quality variability.
Heritage:
Arctic Cat has a long history in powersports, originally known for snowmobiles, expanding into ATVs in the late 1990s/early 2000s. They focused on performance and utility in their ATV lineup.
Model Line:
