Vehicle Information
Hisun Sector 550 Side-by-Side (2015-2023)
The Hisun Sector 550, produced from 2015 to 2023, is a robust side-by-side utility vehicle (UTV) known for its versatility and reliability across various terrains. Powered by a 546cc single-cylinder engine delivering approximately 30.2 horsepower, it offers consistent and ample power for utility tasks and recreational use. This model features an automatic Continuously Variable Transmission (CVT), selectable 2WD/4WD with a front locking differential, and independent dual A-arm suspension with hydraulic shocks, often nitrogen-assisted.
Throughout its production run, the Sector 550 maintained its 546cc engine displacement without major generational changes. However, continuous enhancements were introduced. Electronic Power Steering (EPS) progressively became a standard feature, often reflected in the model name as "Sector 550 EPS". In 2021, the vehicle received significant styling updates, including a new, more modern hood and front fascia, along with 27-inch Obor Crawler tires replacing the previous 26-inch ones, and Vision Wheels faux beadlock aluminum wheels from 2022.
