Now let’s dive deeper into the key performance specs and capabilities of the T-BOSS 550…
Massimo T-BOSS 550 Engine And Transmission
Powering the T-BOSS 550 is a 493cc single overhead cam (SOHC) single-cylinder engine that puts out a strong 33HP. This gives it one of the highest horsepower ratings in the mid-sized UTV segment dominated by 1000cc class models.
The liquid-cooled motor uses electronic fuel injection for optimal fuel mapping and throttle response. It provides potent low-end torque and power through the RPM range, which is essential for conquering tough trails and hill climbs.
All that power is transferred to the wheels via a shaft-driven automatic CVT transmission with high, low, neutral, reverse, and parking. The CVT behaves like an automatic car transmission, keeping the engine in the optimal RPM range and adjusting ratios seamlessly based on speed and load. This makes the T-BOSS easy and convenient to drive without having to shift.
Throttle response is smooth and linear thanks to the electronic fuel injection. Whether rock crawling at low speeds or running wide open across sand dunes, the powertrain offers reliable performance. For those looking for a little more engine braking downhill, the transmission does have a L gear mode.
True Top Speed Of The Massimo T-BOSS 550
One of the most common questions asked by potential T-BOSS 550 buyers is “how fast does it go flat out?”
Based on owner reports, with two average-sized adults onboard, the real world top speed of the Massimo 550 is between 35 to 45 MPH at full throttle depending on the model year.
Its 33 horsepower engine has enough power to push the side-by-side up to these speeds across hard packed dirt or gravel. But engine speed and RPMs will be very high at that road-worthy pace.
For more relaxed trail riding and cruising around off-road, a more reasonable speed is between 35 to 45 MPH, allowing the engine to work less hard. Towing a trailer will also reduce overall top speed.
While it may not match the top speeds of some of its rivals in the same class, the T-Boss has plenty of acceleration and speed capability for recreational off-road fun.
T-BOSS 550 Suspension And Handling
A key part of what makes UTVs so capable off-road is the suspension. The Massimo T-BOSS 550 comes equipped with a fully independent double A-arm suspension setup with adjustable preload shocks.
This provides 9.25 inches of ground clearance and a plush ride quality even over rough terrain. Double A-arms allow each wheel to move independently for greater articulation and traction.
Up front are twin A-arms with preload adjustable shocks offering 10.5″ of travel. The rear also gets a double A-arm design with preload adjustable shocks providing 10.5″ of rear wheel travel.
This allows the T-BOSS to soak up bumps and ruts effectively while maintaining stability. Preload adjustment allows owners to stiffen or soften the suspension.
The 550 puts power down via 25” tires on 12” wheels front and rear. The tread pattern provides plenty of bite for traversing mud, dirt, gravel, and rocks.
Steering components include a rack and pinion system for responsive and accurate steering out on the trails.
Overall the nimble T-BOSS 550 offers great handling for technical off-road conditions as well as high speed desert running thanks to quality suspension components.
Rugged Chassis And Protection
In addition to its off-road optimized suspension, the T-BOSS 550 construction includes a heavy duty steel frame and protective skid plates for tackling rugged terrain.
The frame uses 1.5” diameter steel tubing to provide rigidity and strength without excessive weight. Integrated skid plates shield vital components like the front differential, CVT case, and lower A-arms from impacts underneath.
Other standard protection features include:
- Aluminum front bumper
- Mid-frame Rock Sliders
- Front & Rear A-Arm Guards
So while not loaded with high end protection accessories, the chassis and skids allow T-BOSS 550 owners to drive with confidence off-road knowing it can take some abuse.

Towing, Cargo And Storage
While built for off-road excitement, the T-BOSS 550 also offers great utility for worksites and farms with its cargo and towing capabilities.
The steel tilting cargo bed measures 36 x 47 x 12 inches providing ample room to haul equipment, tools, or hunting gear weighing up to 500 pounds. A manual tilt dump lever makes unloading easy.
Standard 2″ hitch receiver allows the 550 to tow up to 1200 pounds. So it can easily pull small trailers or work tools around the property or campsite. A rear storage box gives you extra secured space for smaller items.
Overall the T-BOSS combines versatile utility and storage with its fun-to-drive performance for both work and play.
Comfort And Convenience Features
The T-BOSS 550 isn’t loaded with all the premium amenities of a Can-Am or Polaris model that can cost twice as much. But Massimo did include some nice comfort and convenience features for the price:
- Tilt Steering – Helps find the optimal driving position
- LED Headlights – Bright illumination on night rides
- 4-Point Harnesses – Keep occupants secure off-road
- Glove Box – Provides in-cab storage
- 2″ Receiver Hitch – Standard towing capability
- Occupant Nets – Help keep legs/knees contained
While it misses extras like power steering, roof, winch, and sound system – the core essentials are covered for a comfortable ride. Considering its sub-$12K price, the T-BOSS 550 offers good basic comfort for side-by-side enthusiasts.

What Owners Are Saying About the Massimo T-BOSS 550
What Owners Are Saying About The Massimo T-BOSS 550
With over 500 miles on my Massimo T-BOSS 550 so far, I’m really impressed at the power and capabilities this affordable side-by-side offers. The 33 horsepower single-cylinder engine has tons of torque for hill climbing, without sacrificing top end speed. I’ve had it up to 45 MPH across some straightaways.
The independent suspension soaks up trails really well and the 25-inch tires provide great traction. My only complaint is the lack of power steering. It really requires manhandling at low speeds or when winching. But the tilt steering helps get it dialed in. For the price, very happy with the speed, utility, and performance of the 550. It’s a lot of bang-for-your-buck!
Brandon S., Massachusetts
I bought the T-BOSS 550 as my first side-by-side. As a ranch hand, I needed something affordable but still rugged and powerful enough for daily chores. The Massimo 550 has worked out great for hauling feed, wrangling cattle, and reaching remote parts of our 500 acre South Texas property.
The 33 horsepower single-cylinder engine has plenty of low end torque for pulling and towing. Switching between 2WD and 4WD is seamless. My only upgrades were adding better shocks and a windshield to keep trail debris down. Hard to beat this side-by-side value under $12K. It just keeps taking the ranch abuse I dish out daily.
Wyatt D., Texas
As an avid hunter and outdoorsman on a budget, the Massimo 550 was the perfect UTV choice for me. I outfitted mine with a winch, roof, windshield and other accessories to be the ultimate hunting rig. It has no problem traversing swamps and rough terrain to reach my remote blind locations.
The big fuel tank provides long range. And the tilting cargo bed with 500 pound capacity carries my deer after a successful hunt. Couldn’t be happier with this affordable, mid-sized side-by-side. Much smoother and faster than my old ATV.
Hunter D., Louisiana
In Summary, Owners Praise The T-BOSS 550 For Its:
- Strong performance from 33HP 493cc single-cylinder engine
- Excellent suspension for off-road handling
- Ample cargo and towing capacities
- Affordability and value compared to rivals
- Surprisingly quick acceleration and 45 MPH top speed
The most common complaints relate to lack of features like power steering. But overall for a sub-$12K sporty UTV, owners agree you get fantastic performance and capability with the Massimo T-BOSS 550.
Massimo T-BOSS 550 Pricing by Year
When the T-BOSS 550 first launched in 2019, it carried an MSRP just under $9,000. But as performance side-by-sides have grown in popularity, strong demand has driven prices up each model year.
The 2023 Massimo 550 now costs $11,299 – a $2,300 or 25% increase over 4 years. Compared to rivals from Polaris, Can-Am, and Honda that all cost over $15K, the T-BOSS remains thousands less despite price hikes.
Bargain hunters may be able to find leftover 2022 models still on dealer lots for under $11K. But expect to pay MSRP or more for the 2023 550. Overall it’s still an affordable performance UTV. But prices are trending upwards like most powersports vehicles.
What is the Best Price for a Used T-BOSS 550?
Since the T-BOSS 550 is still a newer side-by-side model, there are not a huge number of used units for sale currently. But UTV enthusiasts on a tight budget may want to consider a pre-owned 550 to save some money upfront.
Based on market prices, here are typical asking prices for used T-BOSS models:
- 2019-2020: $7,500 – $9,000
- 2021: $9,000 – $11,000
- 2022: $10,000 – $12,000
As with any used vehicle purchase, be sure to thoroughly inspect the machine, get a test drive in, and check for proper maintenance and any damage or abuse before buying.
But for at least $2,000+ less than new, you can potentially get a lightly used Massimo 550 side-by-side in good shape if you don’t mind it being 1-3 years old.
Massimo T-BOSS 550 Top Alternatives
The T-BOSS 550 competes in the hotly contested mid-sized performance UTV segment against models like:
- Polaris RZR XP 1000 – 925cc twin, 72HP, Fox shocks, $15,399
- Can-Am Maverick Sport – 976cc triple, 74HP, Smart-Shox, $13,349
- Honda Talon 1000R – 999cc twin, 64HP, FOX Live Valve shocks, $20,249
- CFMoto UForce 1000 – 963cc V-twin, 64HP, $12,599
So while the Massimo only makes 48HP, it’s priced thousands below rivals. Buyers get 75-90% of their performance at 50-60% of the cost.
The CFMoto UForce 1000 is the closest cross-shop comparison providing similar power (64HP), capacity, and pricing ($12,599) to the value-focused 550. Owners praise its reliability too.
So shoppers should test drive the T-BOSS 550 and CFMoto 1000 back-to-back. But it’s hard to beat the Massimo’s mix of power, handling, and affordability in stock form.
Common Mods and Upgrades
While the bone stock T-BOSS 550 delivers great value and performance right off the showroom floor, there are a few common mods owners make to tailor and enhance their side-by-side:
- Suspension Upgrade – Swap stock shocks for better FOX, KYB or KING units
- Power Steering – Add an electric PS kit to reduce low speed steering effort
- Roof – Add cab enclosure or roof for protection from sun and rain
- Audio – Install side-by-side audio system with Bluetooth for tunes
- Lighting – Upgrade stock lighting with LED light bars and whips
- Winch – Equip a quality winch for self-recovery capability
As a budget-priced UTV, owners don’t expect a lot of bells and whistles from the factory. But the abundant aftermarket for 550 accessories lets buyers upgrade and customize their T-BOSS to their exact needs and style.
What Problems Do T-BOSS 550 Owners Experience?
Overall the Massimo T-BOSS 550 has proven to be a very reliable side-by-side, especially considering its value price point. But a few common owner complaints have emerged:
- CVT Belt Failures – Premature CVT belt breakage or shreds have been reported. Replacing with a high quality belt alleviates this.
- Overheating Issues – Some owners report engine overheating in very slow, technical riding. Upgrading radiator improves cooling.
- Leaking Shocks – Stock shock seals may leak over time. Quality aftermarket shocks fix this nuisance problem.
- Loose Fasteners – Periodically re-tightening chassis bolts and fasteners helps prevent rattling.
- Poor Low-Beam Lights – Switching to higher output headlight bulbs or auxiliary LEDs improves night vision.
- Noisy Drive Chain – Lubing the drive chain periodically reduces noise and wear.
Overall, the T-BOSS 550 has proven to be a reliable and durable machine for owners. But periodic maintenance and fixing minor issues promptly goes a long way towards extended trouble-free operation.
Is the Massimo T-BOSS 550 Still Worth Buying?
In the $10K to $15K sport UTV market, the Massimo T-BOSS 550 remains one of the best values available in 2023. You’d be hard pressed to find more power, performance, and capability for under $12,000 new.
While it lacks some of the premium finish and luxury features of pricier Polaris, Can-Am and Honda models, you still get an incredibly fun, quick, and rugged side-by-side for thousands less.
If you don’t need track-level components and the biggest motor, the bargain 550 has all the grunt and suspension most recreational riders will ever need. New owners consistently rave about the punchy 48HP twin and smooth power delivery both on trail and at high speeds.
So despite the recent price hikes, the Massimo T-BOSS 550 retains its crown as a leading value buy in the hotly contested UTV segment. It’s a proven high-performance side-by-side at an affordable price.
