Kawasaki Brute Force 750 4x4i (2015-2022): A Workhorse with Refined Muscle

When Kawasaki introduced the Brute Force 750 4x4i in 2015, it wasn’t just launching another utility ATV – it was refining a legend. Having spent considerable time with this machine across varied terrain, from muddy trails to rocky inclines, I can confidently say this generation strikes a remarkable balance between raw capability and modern rider comforts. Let’s dive into what makes this ATV a standout in its class.

First Impressions: Commanding Presence Meets Practical Design

The Brute Force 750 4x4i doesn’t whisper – it announces itself. The double-cradle steel frame gives it a purposeful, industrial aesthetic, while color options like Fragment Camo Gray (post-2017 models) or Vibrant Blue add flair to its work-ready demeanor. At 317 kg (699 lbs) wet weight, it’s substantial but never feels unwieldy once you’re in motion.

The cockpit layout deserves praise. The digital dash – featuring a fuel gauge, engine temp readout, and 2WD/4WD indicator – is logically arranged. Kawasaki’s choice to include an hour meter (perfect for maintenance tracking) and dual trip meters shows they understand their audience’s practical needs.

Riding Experience: Where Power Meets Precision

Engine Performance

The 749cc liquid-cooled V-twin is the star here. With 50 HP @ 6,750 RPM and torque peaking between 57.9-59 Nm (42.7-43.5 lb-ft) depending on model year, this engine delivers power in a distinctly Kawasaki way – assertive but controlled. The DFI injection system with dual 36mm Mikuni throttle bodies ensures crisp throttle response whether you’re crawling through mud or accelerating across open fields.

What surprised me most was the engine’s versatility. The automatic transmission (with selectable 2WD/4WD) eliminates gear hunting in technical sections, while the shaft drive maintains reliability. On steep inclines, the engine’s torque curve feels perfectly tailored – no dramatic power surges, just consistent pull.

Handling & Comfort

Kawasaki’s Speed-sensitive Electric Power Steering (EPS) transforms the experience. In tight woods, the steering lightens beautifully at low speeds, reducing arm fatigue. At higher velocities, it firms up appropriately – a smart system that never feels artificial.

Suspension travel (170mm front/191mm rear) handles moderate jumps and whoops with composure. The 5-way adjustable preload (on later models) lets you dial in stiffness for payloads. While not a desert racer, it maintains composure at trail-appropriate speeds.

Ground clearance of 239-240mm (9.4") proved sufficient for most obstacles. I tested it side-by-side with a 2020 Camo model through rocky creek beds – the steel skid plates (aftermarket upgrade recommended for severe use) held up admirably.

Design & Build Quality: Built for the Long Haul

Kawasaki’s choice of high-tensile steel for the frame pays dividends in durability. After 6 years of production (2015-2022), these machines have developed a reputation for resisting frame fatigue – a critical factor for buyers who actually use their ATVs for work.

The 25-inch tires (25/8-12 front, 25/10-12 rear) offer a great balance: enough sidewall for cushioning without excessive squirm. Braking performance from the dual front discs and sealed rear multidiscs inspires confidence, especially when descending with a load.

The Tech That Matters: Thoughtful Additions

While not overloaded with gadgets, the Brute Force 750 4x4i includes smart features:

• Variable Front Differential Control: Switches between open diff for smooth turns and locked for maximum traction
• Hour Meter: Essential for tracking maintenance intervals
• Dual Trip Meters: Perfect for mapping hunting grounds or worksites
• Engine Temp Gauge: Critical for preventing overheating during slow, heavy work

The 35W headlights (upgradeable to LED via aftermarket) provide adequate night vision, though serious night riders might want auxiliary lights.

Competition: How It Stacks Up

Honda Rubicon vs Brute Force 750

Honda’s Rubicon matches Kawasaki in reliability but uses a smaller 518cc engine. While smoother, it lacks the Brute Force’s low-end grunt for towing. Kawasaki’s EPS system also feels more refined than Honda’s mechanical steering.

Yamaha Grizzly 700

Yamaha’s Ultramatic transmission is superior in technical terrain, but the Brute Force counters with better heat management during prolonged heavy loads. The KVF’s V-twin character appeals to those wanting traditional engine feedback.

Can-Am Outlander 650

Can-Am offers more tech (like ECO/Sport modes) and superior suspension. However, the Brute Force’s simpler design translates to lower long-term maintenance costs – a key factor for commercial users.

Maintenance: Keeping the Beast Happy

Critical Service Points

1. Oil Changes: Every 100 operating hours or 6 months with Kawasaki 10W-40 (or equivalent synthetic)
2. Air Filter: Clean every 20-25 hours in dusty conditions (consider oiled foam upgrades)
3. Drive Belt: Inspect every 200 hours – premature wear indicates misalignment
4. Front Diff Fluid: Often overlooked – change every 300 hours
5. EPS System: Annual steering stem bearing lubrication prevents stiffening

Common Upgrades

• Winch Capacity: The stock 1,500 lb winch handles light work, but 2,500 lb aftermarket kits are popular
• Skid Plates: Upgrade to 3/8” aluminum for rocky terrain
• Tire Options: While the 25s work well, many users switch to 27” tires (+2” lift recommended)

The Verdict: More Than Just a Name

The Brute Force 750 4x4i isn’t about being the lightest or fastest – it’s about capability you can trust. That V-twin’s distinctive growl becomes addictive, while the EPS system makes long days manageable. For those needing an ATV that transitions seamlessly from hauling firewood to weekend trail riding, this Kawasaki remains a compelling choice years after its debut.
