Engineered by Access for the atv motorcycle segment, the 2024 Access Xtreme Enduro SP300S utilizes a 280.4 cc (17.1 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 18.8 HP (13.7 kW), transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 67 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Xtreme Enduro SP300S measures 225 kg (496 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (11.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control. The 14.8-liter (3.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
