KYMCO MXU 375 [2008-2013]: A Timeless Workhorse for the Rugged Explorer
Introduction
The KYMCO MXU 375, produced between 2008 and 2013, remains a standout in the mid-size utility ATV segment. Designed to balance rugged capability with everyday usability, this Taiwanese-built quad has earned a reputation as a dependable companion for farmers, hunters, and off-road enthusiasts. While newer models flood the market with flashy tech, the MXU 375’s straightforward engineering and mechanical grit keep it relevant. After spending a week traversing muddy trails, rocky inclines, and open fields on a well-maintained 2012 MXU 375i 4x4 IRS, it’s clear why this ATV still has a loyal following.
Design & Build Quality
The MXU 375’s design screams practicality. Its steel frame, measuring 2,108 mm (83 inches) in length and 1,191 mm (46.9 inches) in height, strikes a balance between compact maneuverability and stable proportions. The 254 mm (10 inches) of ground clearance lets you glide over logs and ruts without hesitation, while the 274.9 kg (606 lbs) dry weight gives it a planted feel—critical when hauling gear or towing.
Color options were limited to no-nonsense Red, Green, and Black, with matte finishes hiding scratches from bushwhacking. The digital dash (backlit for night rides) is refreshingly simple: speedometer, odometer, fuel gauge, and trip meter. No frills, no distractions. The seat height of 810 mm (31.9 inches) accommodates riders of most sizes, though taller users might wish for more legroom during long hauls.
Engine & Performance
At the heart of the MXU 375 is a 366.9 cc air-cooled single-cylinder engine, producing 26 HP (19 kW). While carbureted engines feel antiquated in 2024, the Mikuni carb on this ATV delivers predictable throttle response. Cold starts require patience (a few choke pulls are mandatory), but once warmed up, the engine hums reliably. The CVT automatic transmission shifts seamlessly between High and Low ranges, and the push-button 2WD/4WD toggle lets you adapt to terrain on the fly.
On gravel roads, the MXU 375 cruises comfortably at 55-60 km/h (34-37 mph). The shaft drive eliminates chain maintenance headaches, though it adds weight. Where this ATV shines is low-speed grunt: crawling up steep, rocky slopes in 4WD Low feels effortless, thanks to the torque-rich power delivery. The lack of fuel injection means altitude changes require manual adjustments, but for sea-level riders, it’s a non-issue.
On the Trail: Riding Experience
Comfort: The independent dual A-arm suspension (178 mm / 7 inches of travel front and rear) absorbs trail chatter better than many rivals. It’s no luxury cruiser—hard impacts still jolt the spine—but for a work-oriented ATV, it’s surprisingly plush.
Handling: The 1,217 mm (47.9-inch) wheelbase and 23-24” tires (23/8-12 front, 24/10-12 rear on later models) provide a stable platform. In tight forest trails, the MXU 375 pivots with minimal understeer, though the non-adjustable steering feels heavy at walking speeds.
Braking: Hydraulic discs (dual 180mm up front, single at the rear) offer strong stopping power, even when descending muddy hills. Aftermarket brake pads from MOTOPARTS.store can reduce fade during aggressive use.
Utility: The front and rear racks (rated for ~45 kg / 100 lbs combined) handle everything from firewood to hunting gear. Adding a MOTOPARTS.store aluminum cargo box transforms it into a mobile toolkit.
Competition
The MXU 375’s rivals in the 350-400cc utility class include:
- Honda FourTrax Rancher: Honda’s legendary reliability comes at a higher price. The Rancher’s fuel-injected engine starts easier in cold weather, but its solid rear axle can’t match the MXU’s independent suspension comfort.
- Yamaha Grizzly 350: Lighter and nimbler, the Grizzly excels in technical terrain. However, its chain drive demands more maintenance, and the cargo capacity falls short of KYMCO’s racks.
- Suzuki KingQuad 400: More power (32 HP) and a smoother transmission, but the Suzuki’s complexity leads to costlier repairs. The MXU’s carburetor is far easier to rebuild trailside.
The MXU 375’s sweet spot? Owners who value mechanical simplicity and don’t mind trading a few horsepower for lower long-term costs.
Maintenance: Keeping Your MXU 375 Thriving
1. Carburetor Care
The Mikuni carb is robust but sensitive to stale fuel. Use ethanol-free gasoline when possible, and install a MOTOPARTS.store inline fuel filter. For cold climates, a carb heater kit ($45) prevents icing.
2. Air Filter Vigilance
The foam air filter clogs quickly in dusty conditions. Clean it every 20 hours of riding, and upgrade to a high-flow K&N filter (available at MOTOPARTS.store) for improved airflow.
3. Shaft Drive Service
Change the gear oil every 1,000 km (600 miles). Look for metal shavings—a sign of worn bearings.
4. Suspension Lubrication
Grease the A-arm bushings quarterly. Stiff suspension? MOTOPARTS.store offers greaseable pivot kits for smoother articulation.
5. Tire Upgrades
The stock CST tires are decent, but swapping to Maxxis Bighorns (26x9-12 front, 26x11-12 rear) adds traction in mud and snow.
Conclusion
The KYMCO MXU 375 isn’t about cutting-edge specs—it’s about getting the job done without fuss. Its carbureted engine and steel frame might seem old-school, but that’s precisely why it endures: fewer electronics mean fewer failures. Whether you’re maintaining a ranch or exploring backcountry trails, this ATV rewards those who treat it right. And when it’s time to replace parts or add accessories, MOTOPARTS.store has everything from OEM-spec bolts to winch mounts. The MXU 375 proves that sometimes, “outdated” is just another word for “dependable.”
