Description
The M12 started a revolution. Fueled by a passion for true offroad styling, we engineered this timeless design to truly accent ANY make or model ATV or UTV on the market. Eight symmetrical spokes are highlighted by simple machining accents that elongate the spokes to the edge of the rim. No other wheel style in our industry is more recognized and adored than the M12 Diesel. Attempts have been made to duplicate this style, but M12 Diesel is a MSA Wheels classic and nothing compares to the original. Gloss black paint and just the right amount of micro-machined highlights, own what most consider the best looking ATV wheel ever made.

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.
