A brand-new Campagna T-Rex 16S carries an MSRP of $56,900. That puts it squarely in sports car territory, and out of reach for most riders shopping on a real budget. But on the used market, older T-Rex models regularly sell for $12,000 to $19,000. Sometimes less. The catch: you need to know which model years hold up, where listings actually appear, and which "deals" are just cosmetically patched wrecks with hidden frame damage.
If you're searching for a T-Rex motorcycle for sale under $20,000, this guide covers real sold pricing by generation, the five best places to find one, and exactly what to inspect before signing anything. For the full model-by-model breakdown (including current-production pricing), see our complete T-Rex buyer's guide.
What Is a T-Rex, and Why Are They So Expensive New?
The Campagna T-Rex is a three-wheeled, open-cockpit vehicle built by Campagna Motors in Boucherville, Quebec. Two wheels up front, one in the rear, and a motorcycle engine bolted into a chromoly tubular steel frame. It weighs roughly 1,100 lbs, hits 60 mph in about 3.9 seconds, and gets registered as a motorcycle in most US states.
New T-Rex 16S models use the BMW K1600 inline-six (1,649cc, around 160 hp). The 16SP adds adjustable suspension and upgraded bodywork, pushing past $65,000. Hand-built production in small batches is the main reason for the sticker price. Campagna produces roughly 200 to 300 units per year, so dealer inventory is always thin.
That limited production also means used values drop faster than most motorcycles. Few buyers are willing to pay near-new prices for a niche vehicle with limited parts distribution and specialized insurance requirements. That depreciation is your window into ownership under $20,000.
T-Rex Models That Actually Sell Under $20,000
Not every T-Rex qualifies. The 16S and 16SP from 2015 onward almost always trade above $25,000. To land under twenty grand, you're shopping for earlier Kawasaki-powered generations.
2003 to 2007: Kawasaki ZX-12R Engine (1,200cc)
These first-generation production T-Rex models used the Kawasaki ZX-12R inline-four making 178 hp. They're the most affordable T-Rex you'll find, typically selling between $9,000 and $15,000 depending on mileage and cosmetic condition. The ZX-12R engine is proven across hundreds of thousands of sport bikes, and parts are still widely available through any Kawasaki dealer.
2008 to 2012: Kawasaki ZX-14R Engine (1,400cc)
Campagna upgraded to the Kawasaki ZX-14R (197 hp) around 2008. These sell for $14,000 to $22,000. Low-mileage examples under 5,000 miles tend to hold above $20,000, but anything with 8,000 or more miles and minor cosmetic wear regularly drops into the high teens. This is the sweet spot for a sub-$20K T-Rex with serious power.
2013 to 2014: Early BMW K1600 Transition
Campagna started fitting the BMW K1600 inline-six around 2013. These transition-year models occasionally appear under $20,000 with higher mileage (12,000+ miles), but most sell in the $19,000 to $24,000 range. If your budget has some flex, a 2013 with the BMW engine offers a smoother, more refined powerplant.
Used T-Rex Motorcycle Pricing: What They Actually Sell For
Asking prices on Craigslist and Facebook Marketplace typically run 10 to 20 percent higher than what sellers actually accept. Here's what used T-Rex three-wheelers have sold for in 2025 and 2026 based on completed auction and private-sale data.
| Model Year | Engine | Typical Mileage | Sold Price Range |
|---|---|---|---|
| 2003 to 2005 | Kawasaki ZX-12R (1,200cc) | 8,000 to 15,000 mi | $9,000 to $14,000 |
| 2006 to 2007 | Kawasaki ZX-12R (1,200cc) | 5,000 to 12,000 mi | $12,000 to $16,000 |
| 2008 to 2010 | Kawasaki ZX-14R (1,400cc) | 6,000 to 15,000 mi | $14,000 to $19,000 |
| 2011 to 2012 | Kawasaki ZX-14R (1,400cc) | 4,000 to 10,000 mi | $16,000 to $22,000 |
| 2013 to 2014 | BMW K1600 (1,649cc) | 5,000 to 12,000 mi | $17,000 to $24,000 |
| 2015 and newer (16S) | BMW K1600 (1,649cc) | Any | $25,000+ |
The best value under $20,000 is a 2006 to 2010 model with the Kawasaki engine, under 12,000 miles, in solid mechanical condition with a clean title.
Where to Find a T-Rex Motorcycle for Sale
T-Rex three-wheelers are not sitting on the floor at your local Harley dealership. Finding one takes targeted, regular searching across multiple platforms.
Cycle Trader and AutoTrader
Both platforms list T-Rex models under "three-wheelers" or "trikes." Filter by price ($0 to $20,000) and sort by distance. Inventory is thin. Expect 5 to 15 listings nationwide at any given time. Check weekly and set up email alerts.
Facebook Marketplace and Craigslist
Private sellers list T-Rex motorcycles here more than anywhere else. Search "T-Rex motorcycle," "Campagna T-Rex," and "T-Rex trike for sale." Most private-sale T-Rex units move within two to three weeks of listing, so saved-search alerts are essential.
Bring a Trailer and Cars and Bids
Online auction platforms occasionally feature T-Rex listings. Bidding is transparent, with verified photos and maintenance records. Sold prices here tend to reflect fair market value, making these auctions a good pricing benchmark even if you don't bid.
T-Rex Owner Communities
The Campagna T-Rex owners' group on Facebook runs an active classifieds section. Sellers in these groups tend to be enthusiasts who maintained their vehicles properly, and prices often come in below dealer asks. The CampagnaMotors.com forum is another spot to watch.
Salvage Auctions (Copart and IAAI)
Copart and IAAI occasionally list T-Rex vehicles after minor collisions, often selling for $6,000 to $10,000. The risk: salvage-title T-Rex units are nearly impossible to get full-coverage insurance on, and resale value drops to almost nothing. Only go this route if you have the mechanical knowledge to assess frame damage yourself.
What to Inspect Before Buying a Used T-Rex
A T-Rex is not a standard motorcycle purchase. It combines car-like suspension components, a motorcycle drivetrain, and a hand-welded frame. Here's what matters most during a pre-purchase inspection.
Frame and Chassis
The T-Rex frame is welded chromoly steel tubing. Look for cracks around the engine mounts and front suspension pickup points. Any visible weld repairs near the main frame rails signal a significant prior impact. Walk away from repaired frames unless you can verify the shop that did the work and see documentation.
Engine Health
Both the Kawasaki and BMW engines are mass-production motorcycle powerplants with proven durability. A properly maintained ZX-14R engine runs 40,000+ miles without major issues. Check for oil leaks around the valve cover gaskets (common on higher-mileage Kawasaki engines) and listen for timing chain rattle on cold start. Ask for service records showing oil changes every 3,000 to 5,000 miles.
Suspension and Steering
The front suspension uses unequal-length A-arms with coilover shocks, similar to a formula car setup. Jack up the front end and grab each wheel at 12 and 6 o'clock. Any clunking or play means worn ball joints, which cost $300 to $500 per side to replace at a shop familiar with the platform.
Final Drive Belt
Most T-Rex models use a belt final drive. Inspect for cracking, missing teeth, or glazing on the belt surface. A replacement Gates belt costs roughly $120 for the part, but labor adds $200 to $400 if you're not doing it yourself.
Title and Registration
Verify the title reads "motorcycle" or "autocycle" for your state. Classification varies by state. Some states require a motorcycle endorsement to operate a T-Rex. Others allow a standard driver's license. Confirm with your local DMV before you commit, and get an insurance quote before you close the deal.
Three-Wheeler Alternatives Under $20,000
If T-Rex inventory is dry in your area, two alternatives deliver a similar open-air driving experience under the same budget. Neither matches the T-Rex's raw performance, but both are easier to find and cheaper to insure.
| Vehicle | Engine | New MSRP | Used Under $20K? | Key Difference |
|---|---|---|---|---|
| Campagna T-Rex (used) | Kawasaki/BMW 4 or 6-cyl | $56,900+ | Yes (pre-2013) | Open cockpit, track-focused |
| Polaris Slingshot | ProStar 2.0L 4-cyl (203 hp) | $22,499+ | Yes (2015 to 2020) | Side-by-side seating, more common |
| Can-Am Spyder (used) | Rotax 1330cc triple (115 hp) | $18,499+ | Yes (2014 to 2019) | Touring-oriented, Y-frame layout |
A 2017 to 2019 Polaris Slingshot SL with 10,000 miles typically sells for $13,000 to $17,000. It's the closest alternative to a T-Rex in raw driving feel, with far easier parts sourcing and lower insurance premiums.
Common Mistakes When Shopping for a T-Rex Under $20,000
Skipping the insurance quote. T-Rex insurance runs $1,500 to $3,000 per year for full coverage, depending on your state and driving record. Some carriers refuse to cover them at all. Call your insurer before you shake hands on a deal.
Buying a salvage title to save $5,000. A salvage-title T-Rex might look tempting at $8,000, but full-coverage insurance is nearly impossible to obtain. Resale value drops to almost nothing. You also cannot verify whether the frame was straightened properly without a professional jig check.
Skipping the pre-purchase inspection. A $200 PPI at a shop familiar with three-wheelers (or sport bike mechanics at minimum) catches deferred maintenance before it becomes your problem. The engine is standard Kawasaki or BMW, so any competent motorcycle mechanic can assess it.
Overpaying for low miles on a sitting vehicle. A T-Rex with 2,000 miles that sat in a garage for six years often needs more work than one with 12,000 regularly ridden miles. Dried seals, corroded brake lines, and degraded fuel system components are more expensive to fix than normal wear items on a used T-Rex that was actually ridden.
Forgetting about riding gear. The T-Rex is an open-cockpit vehicle. Most models have no windshield. At 70 mph, road debris and wind are constant. You need a DOT-rated motorcycle helmet, wrap-around riding glasses or goggles, and a solid pair of leather gloves at minimum.
Gear Up Before Your First T-Rex Ride
Owning a T-Rex under $20,000 is realistic if you target pre-2013 Kawasaki-powered models, search consistently across multiple platforms, and inspect carefully before buying. Budget another $300 to $600 for proper riding gear if you don't already have it. The open cockpit makes a quality helmet and eye protection non-optional, not just nice to have. If you're building a rider kit from scratch, our helmet collection is a solid starting point.
