Honda TRX 500 FourTrax Foreman/Rubicon (2015–2019): A Legacy of Rugged Dependability

When Honda stamped the TRX 500 badge on its FourTrax Foreman and Rubicon ATVs, it wasn’t just building another utility quad—it was refining a legend. Between 2015 and 2019, this generation solidified Honda’s reputation for crafting machines that balance workhorse grit with trail-ready agility. After spending days testing a 2018 Foreman 4x4 EPS and a Rubicon model back-to-back, it’s clear why these ATVs remain sought-after even as newer models emerge. Let’s dive into what makes this generation stand out—and where MOTOPARTS.store can help you elevate its capabilities.

Design & Build Quality: Built to Outlast the Elements

The TRX 500’s design language screams “no-nonsense.” Its steel double-cradle frame, shrouded in durable plastic bodywork, feels like it could survive a tumble down a rocky incline—and probably has. The Foreman leans into utilitarian charm with blocky lines and functional racks, while the Rubicon adds subtle flair with color-matched accents and slightly more aggressive fender flares.

Color options ranged from understated Olive and Shale Blue to eye-catching Active Yellow and Honda Phantom Camo®, ensuring there’s a finish for every personality. Standout features include:
- Steel front/rear racks rated for 29 kg (64 lbs) and 59 kg (130 lbs) respectively
- 35W halogen headlights that cut through pre-dawn fog (upgradeable to LED via aftermarket kits)
- EPS (Electronic Power Steering) on higher trims, a game-changer for long days hauling feed or navigating root-choked trails

Engine & Performance: Carb vs. Fuel Injection Showdown

Honda offered two engine configurations during this generation:

| Specification | Foreman (Base) | Rubicon & Premium Trims |
|---------------------|----------------------------------|----------------------------------|
| Displacement | 475cc (28.98 cu in) | 499cc (30.45 cu in) |
| Fuel System | Keihin® 36mm Carburetor | PGM-FI Fuel Injection |
| Max Power | ~32 HP | ~38 HP |
| Transmission | 5-speed manual / Auto clutch | Automatic DCT / Hydro-Mechanical|

*Estimates based on comparable models; Honda rarely publishes ATV power figures.

The Carbureted Foreman rewards patience. Cold starts require finesse with the choke, but once warmed up, the 475cc mill delivers linear power perfect for steady trail pacing or pulling a small trailer. The manual transmission’s auto-clutch is a delight—shift without stalling, ideal for new riders.

The Fuel-Injected Rubicon is where things get interesting. Thumb the electric starter, and the 499cc engine barks to life instantly, even at -5°C (23°F). The DCT transmission (on select models) eliminates shifting entirely, letting you focus on picking lines through mud pits.

Both engines share a liquid-cooled design and semi-dry sump lubrication, critical for preventing overheating during slow crawls.

On & Off-Road Handling: Where the TRX 500 Shines

Suspension Setup

• Front: Independent double-wishbone with 185mm (7.3") travel
• Rear: Swingarm with single shock (Foreman) / Independent dual-arm (Rubicon) up to 215mm (8.5") travel

The base Foreman’s suspension feels tuned for hauling firewood—stiff but unflappable under load. The Rubicon’s upgraded rear suspension soaks up whoops and fallen logs with surprising composure.

Driveline Mastery

Honda’s TraxLok® system lets you switch between 2WD and 4WD on the fly. Lock the front differential, and the TRX 500 becomes a hill-climbing beast. We tested this on a 35° muddy slope—with EPS engaged, the front wheels dug in without wrestling the bars.

Ground clearance ranges from 191mm (7.5") on the Foreman to 249mm (9.8") on Aussie-spec models. Combined with 25x8-12 front / 25x10-12 rear tires (forecastle!), it straddled obstacles that stalled lesser quads.

Comfort & Ergonomics: All-Day Rideability

At 869mm (34.2") seat height, the TRX 500 accommodates riders from 160cm (5’3”) to 195cm (6’5”). The bench seat is firmer than a Polaris’ plush throne but prevents numb legs during marathon rides.

Standout ergonomic touches:
- Tilt-adjustable handlebars (on EPS models)
- LCD digital dash with fuel gauge and 4WD indicator
- Sealed drum brakes (rear) that avoid disc corrosion in swampy conditions

Competition: How the TRX 500 Stacks Up

• Differential Fluid: Annually or 3,200km (2,000mi)
• Valve Adjustment: Every 800hrs—Honda’s OHV design is famously low-maintenance

MOTOPARTS.store Upgrade Recommendations

2. SSR Slotted Brake Discs: Swap the front drums for better stopping power.
3. Adjustable Shock Kit: Transform the Foreman’s ride quality without Rubicon-level costs.

Final Thoughts: The Swiss Army Knife of ATVs

The 2015–2019 TRX 500 series doesn’t excel at any single thing—it masters the art of compromise. It’s capable enough for serious off-roading yet refined enough for daily chores. While rivals boast higher specs on paper, few match its bulletproof reliability.

Whether you’re reviving a weathered Foreman or optimizing a Rubicon for overlanding, MOTOPARTS.store has the upgrades to make your TRX 500 outlive, outwork, and outplay the competition. Now, go get it dirty.
