Understanding the Legacy: Why the ’87 Trail Boss Still Matters

Before we talk dollars and cents, let’s appreciate what we’re looking at. The 1987 Trail Boss 250 wasn’t just another quad; it was a game-changer. This was one of the very first American-made 4×4 ATVs with an automatic transmission (the Polaris Variable Transmission, or PVT) and MacPherson strut front suspension.

It was tough, simple, and reliable. For many riders, this was the machine that defined utility and fun in the 80s. That history is a big part of its appeal today. Collectors love it for its place in ATV history, and new riders appreciate its straightforward, easy-to-ride nature.

Understanding this gives you context. You’re not just evaluating an old machine; you’re assessing a piece of off-road history. This heritage provides one of the core benefits of 1987 polaris trail boss 250 value holding steady for machines in good condition.

The Definitive 1987 Polaris Trail Boss 250 Value Checklist

Ready to get your hands dirty? This is our comprehensive 1987 polaris trail boss 250 value guide. Grab a flashlight and a notepad, and let’s walk through the machine piece by piece. A machine’s value is the sum of its parts and condition, so don’t skip any steps.

Engine and Drivetrain: The Heart of the Machine

The 2-stroke, single-cylinder engine is the soul of the Trail Boss. Its condition is the single biggest factor in the quad’s value.

Compression Test: This is non-negotiable. Get a simple compression tester. A healthy 2-stroke should be reading 110-130 PSI. Anything under 100 PSI suggests a worn top end (piston and rings), which is a significant repair cost that will lower the value.
Cold Start: Does it fire up easily from a cold start with the choke? Hesitation or difficulty starting can point to carburetor issues or low compression.
Smoke Signals: A little blue smoke on startup is normal for a 2-stroke. However, excessive, continuous blue smoke means it’s burning too much oil (bad crank seals or oil pump issues). White smoke could indicate water getting into the cylinder.
PVT Clutch Engagement: Put the ATV in gear. Does it engage smoothly without jerking or making loud clunking noises? A worn-out clutch is a common and costly fix.

Frame and Suspension: The Backbone of the Ride

A solid frame is critical for safety and value. A compromised frame can turn an otherwise decent quad into a parts machine instantly.

Inspect for Cracks: Carefully check all frame welds, especially around the A-arm mounts, steering stem, and rear axle carrier. Look for hairline cracks or evidence of sloppy re-welding.
Check for Bends: Look down the length of the frame from the front and back. Does everything look straight and symmetrical? A bent frame from a hard impact is a deal-breaker for most buyers.
Suspension and Bushings: Push down hard on the front and rear racks. The suspension should compress and rebound smoothly. Grab the wheels and try to wiggle them side-to-side. Excessive play indicates worn-out wheel bearings or A-arm bushings.

Plastics and Cosmetics: The First Impression

While mechanical health is key, cosmetics are what people see first. Good plastic can dramatically increase perceived value.

Cracks and Breaks: Original, uncracked fenders are rare and valuable. Look for stress marks (white lines in the plastic) and zip-tie repairs.
Fading and Shine: Has the plastic been stored indoors, or is it chalky and faded from the sun? Some of this can be restored, but original shine is a huge plus.
Original Decals: Believe it or not, having the original 1987 graphics and warning labels intact is a big deal for collectors and adds a surprising amount to the value.
Seat Condition: Check for rips, tears, or a waterlogged foam cushion. A new seat cover is an easy fix, but it’s a cost you need to factor in.

Brakes, Tires, and Controls: The Safety Essentials

These components tell you a lot about how the ATV was maintained. This is where our 1987 polaris trail boss 250 value tips focus on safety.

Squeeze the brake levers. Do they feel firm or spongy? Spongy brakes mean air in the lines or a failing master cylinder. Check the tire tread depth and look for dry rot (cracks in the sidewalls). A matching set of tires with good tread is a great selling point.

Condition Tiers: From Project Quad to Showroom Classic

So, where does your Trail Boss land? We’ve broken it down into four general value tiers. Note: These are estimated 2023-2024 market ranges and can vary by location.

Tier 1: Parts Machine / Major Project ($100 – $400)

This quad is not running. It may have a seized engine, a bent frame, or is missing major components. Its value lies solely in its usable parts like wheels, plastics, or transmission components.

Tier 2: Rough Rider ($400 – $800)

It runs and rides, but it’s not pretty. The engine might be tired (low compression), the plastics are likely cracked or faded, and the brakes and suspension need work. This is a functional machine but requires significant TLC. This is often where you find the most common problems with 1987 polaris trail boss 250 value degradation.

Tier 3: Solid Trail-Ready Quad ($800 – $1,500)

This is the sweet spot for many. The engine starts easily and has good compression. The plastics are intact, maybe with a few scratches. The brakes, tires, and 4WD all work as they should. It’s been maintained and is ready to hit the trail today.

Tier 4: Restored / Survivor ($1,500 – $2,500+)

This is a rare find. It’s either an extremely low-hour, all-original “survivor” with pristine plastics and decals, or a meticulously restored machine. Everything works perfectly, it’s cosmetically near-perfect, and it likely has a title. These command a premium from collectors.

Common Problems That Tank Your 1987 Polaris Trail Boss 250 Value

When you’re trying to figure out how to 1987 polaris trail boss 250 value your machine, knowing what to run away from is just as important as knowing what to look for. Here are the biggest value-killers:

Failed 2-Stroke Oil Injection: The oil pump can fail, starving the engine of oil and seizing it. Many owners pre-mix fuel as a safety measure. If it’s still on the injector, verify it works or factor in a top-end rebuild.
Cracked or Rusted Frame: As mentioned, this is a major safety issue and almost always relegates the quad to “parts machine” status.
Transmission Noises: Whining, grinding, or difficulty shifting are red flags for serious internal transmission problems, which are labor-intensive to fix.
Electrical Gremlins: Brittle, corroded wiring can cause endless headaches with lighting, charging, and ignition systems. Check that the lights work and the battery holds a charge.

Sustainable Value: The Long-Term 1987 Polaris Trail Boss 250 Value Care Guide

Maintaining or increasing your ATV’s value is all about consistent care. Adopting a sustainable 1987 polaris trail boss 250 value mindset means focusing on preservation and proper maintenance, which is also the most eco-friendly approach.

This is more than just a machine; it’s a classic. Following a good 1987 polaris trail boss 250 value care guide is crucial.

Use Quality 2-Stroke Oil: Don’t cheap out. A quality TC-W3 rated oil prevents carbon buildup and protects engine internals, preserving that all-important compression.
Keep it Clean and Covered: The number one enemy of plastic and decals is UV radiation from the sun. Storing the quad indoors or under a quality cover is the best way to prevent fading and cracking.
Address Small Issues Promptly: A small oil leak or a frayed cable will only get worse. Following maintenance best practices means fixing things as they pop up, preventing a small problem from becoming a major, value-killing failure.
Proper Fluid Disposal: Being an eco-friendly 1987 polaris trail boss 250 value owner means responsibly disposing of used gear oil and other fluids at a proper recycling facility.

Frequently Asked Questions About the 1987 Polaris Trail Boss 250 Value

Is a 1987 Polaris Trail Boss 250 a good beginner ATV?

Absolutely. Its automatic transmission, manageable power, and sturdy build make it an excellent choice for new riders. Its simplicity also makes it a great machine for someone wanting to learn basic ATV maintenance.

Are parts still available for a 1987 Trail Boss 250?

Yes, but it’s a mix. Many common maintenance parts like brake pads, carburetor kits, and bearings are readily available from aftermarket suppliers.
