Air-Cooled Scooter Engines | Urban commuting, short trips | Air-cooled system (no coolant required) ▲ Aluminum alloy body (200 kg/m³) 150cc displacement (ISO 286-1) | Lightweight (easier handling) Low maintenance (no coolant checks) Cost-effective | Higher heat buildup (may reduce longevity) Lower power output (suitable only for light loads) |
Liquid-Cooled Sport Engines | High-speed touring, track racing | Liquid-cooled (ISO 9920) 250-400cc displacement (ISO 286-1) High RPM capability (10,000 RPM+) | Better thermal management (longer engine life) Higher power output (superior acceleration) | Heavier (reduces agility) Complex cooling system (higher maintenance) |
Off-Road 4-Stroke Engines | Trail riding, off-road adventures | 4-stroke cycle (EPA-compliant) Rugged aluminum frame (ASTM B221) 125-250cc (ISO 286-1) | Durability (withstands harsh terrain) Lower emissions (meets EPA standards) | Heavier frame (reduces fuel efficiency) Less suitable for urban use |
Electric Motorcycle Motors | Zero-emission commuting, city riding | Brushless motor (ISO 14308) 4 kWh battery pack (IEC 62660-2) 0-60 mph in 4 sec (SAE J1349) | Zero emissions (environmentally friendly) Instant torque (responsive acceleration) | Limited range (80-120 miles) Charging infrastructure dependency |
High-Performance V-Twin Engines | Cruiser bikes, long-distance touring | V-twin configuration (60° angle) 1,200cc+ displacement (ISO 286-1) Smooth power delivery (low-end torque) | Iconic sound (rich exhaust note) High torque (superior towing capacity) | Higher weight (reduces maneuverability) Higher cost (premium components) |
Compact Commuter Engines | Daily urban commuting, short-distance travel | 50-125cc displacement (ISO 286-1) Lightweight frame (150 kg/m³) Fuel-efficient (40+ MPG) | Fuel efficiency (low operating costs) Easy parking (small footprint) | Limited power (unsuitable for highways) Less durable (lightweight materials) |
