Suzuki LTR 450 Quad Racer Specs and Review 2022

Suzuki LTR 450 Quad Racer: In 2006, we saw the launch of the LTR 450 the high-performance machine designed to excel on the motocross course. 

Utilizing the skills from WPSA Pro ATV racer Doug Gust Suzuki’s team of experts began developing the four-wheeler that was to become the genesis of the next-generation sport quads. 

Suzuki LTR 450 QuadRacer

The result? A race-ready beast that was swift and agile, performed flawlessly and fueled by the adrenaline of the elated, brave riders.

The Suzuki LTR 450 (a.k.a. the QuadRacer LT-R450) is without doubt one of the best sport ATVs ever. 

With a 450cc RM-Z450 engine, a sturdy design, impressive suspension, and an aggressive design The purpose-built machine racked up authentic sport ATVs during the beginning of the 2000s.

The LTR 450 is the only vehicle that has performed better in replacing the compact but innovative LT250R. 

Similar to its sibling that it is based on, the LTR 450 has features that have been awarded and accolades that are etched in the books of history.

It also has successfully widened the sport riding market which was a niche that was first created by its predecessor almost four decades ago.

Read on to discover more about the specs and features, notable characteristics, and improvements to the design that are available on this model. Suzuki QuadRacer LTR 450.

Suzuki LTR 450 QuadRacer

Born for the Racetracks

Since its debut in 2006, the LTR 450 (Suzuki QuadRacer LT-R450) has proven itself to be an undisputed force within the realm of Motocross and GNCC racing, similar to how the champion racing driver Dustin Wimmer has commanded respect within the ATV Pro MX scene. 

From the beginning, the two Wimmer, as well as the machine that was specifically designed, have taken home back-to-back championships in the same series.

However, it wasn’t just Wimmer who contributed positively to the reputation of the four-wheeler. 

Race champion Doug Gust played a vital role in the research and development as did the factory Suzuki pilot Chris Borich triumphed over 10/13 rounds of the 2009 GNCC series riding the LTR 450.

Test riders can confirm that the Suzuki LT R450 is also able to excel on a variety of terrains beyond GNCC-style MX tracks including Trailways that are wooded or mud pits, as well as steep hills. 

The fuel-injected, four-stroke engine, a big stance the centered exhaust, and long-travel suspension make this possible even after it has just come off the floor of the dealership.

In contrast to other models, It doesn’t produce a sudden power like its competitors. The front end is able to lift off the ground easily thanks to its incredible throttle response.


It’s more than the power that makes the QuadRacer above other quads of the same class. 

While every quad claims to give consumers something different or distinctive but it is the LTR 450 was the only ATV with a sporty design at its time that broke out of the cliché.

It was race-ready, competitively-race-ready, and with no need for expensive suspension, chassis, and other bolt-on components. 

If it needed something, suggested add-ons could include LTR bar nerfs 450, Yoshimura Cherry Bomb, as well as a kill switch which is more aesthetic (or because of the preference of the rider) instead of enhancing performance.

2007 LTR450 QuadRacer Onwards

The improvements only increased with the LTR450 QuadRacer from 2007 and beyond and Suzuki focused on eliminating the weaknesses of 4x4s and enhancing its strengths. 

There aren’t any changes to the exterior. However, inside there are over 100 modifications made to its suspension and engine systems.

The most important changes are an improved power output at the low end as well as a resprung/revalved suspension that has been re other minor improvements. 

In the end, the QuadRacer was upgraded by 3 horsepower in claimed horsepower, more substantial suspension, and improved performance on the road.

Suzuki LTR 450 Specs & Features (QuadRacer LT-R450) Engine

A liquid-cooled, four-stroke DOHC engine that has a 95.5 x 62.8 millimeter (3.76 2.47 inches). 2.47 inches) bore-stroke ratio and 11.7:1 compression ratio bring this mid-sized sport ATV to life. 

Engine displacement is 450cm 3. (27.5 inches 3.) which is achieved through electronic fuel injection that is more efficient and responsive than a conventional carburetor.

The engine configuration allows for it a speed of 78 mph (125-km/h) max speed as well as the maximum horsepower of 41 horsepower (41.6 PS). For torque, it’s possible to conclude that the highest value for the LT R450 is approximately 43.9 Nm (4.48 kg-m, 32.44 ft-lb) +18% at 7,600 RPM in reference to the powerplant of the RM-Z450 parent.

Fuel & Lubrication

The Suzuki LTR450’s carburetion system uses fuel injection and an injector with multi-holes and a throttle body is 42 millimeters (size up to 43 millimeters in post-2007 models). 

Reserve capacity for fuel to 10- L/2.6 US gallons of unleaded gasoline that has a RON 90 or greater rating (RON 95 outside of North America) containing < five percent MBTE, less than 10 percent ethanol, or 5 % methanol.

It features a dry-sump system for lubrication that includes the use of a foam air filter made of polyurethane. The system for lubrication (called Suzuki Advanced Sump System) is brand new and incorporates two feed pumps,

one that supplies the transmission and a second scavenger pump that feeds the crankshaft, as well as other components of the engine. The use of two separate feed pumps results in less compact crankcases and improves the LTR 450’s clutch and shifting feeling.

On the other hand, the capacities of oil are as follows: 1.2 L/1.3 US quarts (change), 1.3 L/1.4 US quarts (filter change) as well as 1.4 L/1.5 US quarts (overhaul). 

The recommendation of the manufacturer is SAE 10W-40 Suzuki Performance 4-stroke oil with an API SJ+ grade that meets JASO T903MA standards. Based on the ambient temperature it is possible to select different viscosity grades such as SAE 10W-30 or 10W-50, 15W-40, 15W-50, or 20W-50.


Manual (close-ratio) 5-speed variable mesh return device (left-foot operated) as well as a wet multi-plate clutch assembly that has the pattern of a gearshift that is 1-down-4-up deliver motor power for the wheel. An RK the 520SMOZ10S chain (with the 96 links and a joint) manages wheel spin.

Fuel injection mapping re-mapping using the aid of a Yoshimura Cherry Bomb boosts the performance of the quad. 

The installation of this part is best done by altering the gearing, particularly moving to a 12-tooth rear sprocket.

This boosts lower-end torque and makes the car better to be used on trails, without having to sacrifice the ground clearance.

Primary Reduction Ratio 2.851 (77/27)
Final Reduction Ratio 2.571 (36/14)
Transmission Gear Ratio (Low) 2.076 (27/13)
Transmission Gear Ratio (2nd) 1.647 (28/17)
Transmission Gear Ratio (3rd) 1.333 (28/21)
Transmission Gear Ratio (4th) 1.095 (23/21)
Transmission Gear Ratio (Top) 0.913 (21/23)

Suzuki LTR 450 QuadRacer

Tires & Brakes

The stock rubber is made up of tubes of Dunlop KT381/KT385 compound tires that measure AT20 x 7 R10 in the front, and AT18 10 R8 (view on Amazon) at the rear. The rim sizes are 10 x 5.5 AT, and eight x 8.0 AT, with an 11/110 bolt pattern as well as 10 inches 1.25 mm for lug nuts. 

For airing the tires you should use 45 kPa as the pressure recommended (0.45 kg/cm2, 6.5 psi), in the event that the payload capacity doesn’t exceed 110 kg (243 pounds).

The front-wheel hubs are made of aluminum, with the rear hubs made of steel forged. 160 millimeter (6.3-inch) two hydraulic discs sporting 25.4-mm twin-piston Nissin calipers are attached to the hubs on the front. 

Additionally, a 190-mm (7.5-inch) hydraulic disc that has a single-piston 34-mm Nissin hydraulic caliper sits on the back axle. A parking brake operated by hand completes the braking system on the QuadRacer.


In the diamond-shaped metal frame of backbones is an independent double-wishbone that has oil-damped coil overs as well as an imposing rear swingarm, with piggyback reserve Kayaba air-oil shocks. 

Both shocks, front and back, can be adjusted, feature a stain-resistant coating, and offer wheel travel of 254mm (10 inches) and 277 millimeters (10.9 inches).

The angle of the steering is 41deg the angle of the caster is 8deg and the trail length of 30 millimeters (1.18 inches). 

The distance between both axles (wheelbase) is 1,285 mm/50.6 inches. The radius of rotation is 3.5 millimeters (11.5 feet) and the clearance to the ground is 240 millimeters (9.44 inches).

The suspension system on the LTR 450 is responsible for the vehicle’s low center of gravity and provides plenty of wheel travel across all four wheels. 

The spring preload and rebound damping can be completely adjusted, with both low and high-speed compression damping adjustable independently.

The material used for the swingarm provides the necessary rigidity required to make a racer and smooth operation over rough tough terrain. 

In all this Suzuki QuadRacer has the widest tracks with the longest wheelbase and travel, as well as the lowest seating heights and centers of gravity of its class.


The overall dimensions of the vehicle are 72.6 49 and 42.7 inches (1,845 1 245 x 1,085 millimeters, L W x H) which is the exact number of measurements used across all LTR 450 units that are released in all markets. 

The front and rear tracks measure 1,045 millimeters (41.1 inches) and 985 millimeters (38.8 inches) respectively.

The seat height is perfect for taller to medium-built riders with a height of 30.7 inches (780 millimeters). Dry mass is 167 kilos (368 pounds) which is slightly heavier, however still within the same category as its competitors such as that is the Honda TRX 150R and Yamaha YFZ450.


One of the factors that contribute to one of the main reasons for LTR 500‘s dry mass is the frame, which is made from high-tensile stainless steel (the same as the swingarm). 

Suzuki decided to keep the frame the same and not swap it out for an aluminum frame in spite of the market trend. 

Instead of altering the chassis the brace on the rear of the fender as well as the brake pedal came constructed of aluminum/forged aluminum. 

In the same way, the clutch, as well as the magneto cover, were constructed from magnesium alloy which was light that helped to reduce the weight.

Other weight savings efforts include components like the machine’s cylinder bore, plated with a nickel-phosphorus-silicon-carbide coating (a.k.a. SCEM or Suzuki Composite Electrochemical Material). 

SCEM plating is less heavy which results in weight reduction, plus improved heat transfer, more precise clearance between the piston and the cylinder, as well as improved wear reduction.


The riding posture is designed and is based on Doug Gust’s suggestions during the development of the LTR 450 in the year 2006. 

It is modeled after the racing style of professional racers and has a perfect relationship between the footpegs with a serrated 46mm and the traditional T-shaped seat and the handlebars.

The overall design is aggressive and is possible with Champion Yellow and White. In 2008, the Suzuki LT-R450, in particular, features the Limited Edition model that came with black frames, wheels and bodywork, and a red graphic package.

Room for Improvement

The Suzuki LTR450 QuadRacer’s admirable attributes outweigh its shortcomings and make it appear perfect. But, there are two notable items that users would like to see change within the unit.

  • First of all, it’s the largest width of 49 inches, which is a disadvantage with regards to the machine’s appeal to weekend riders who are casual.
  • The footpeg’s height is quite too high, which makes the 4×4 feel a bit heavy when turning.

Although the width of the QuadRacer is an established fact due to its motocross-specific design Nerf bars that have built-in pegs (two inches less than the stock) will easily fix the quad racers’ tendency for tipping over.

About Suzuki

Suzuki Motor Corporation is a Japanese firm that is well-known for its market-leading products such as Suzuki LTR 450

 Like many ATV manufacturers, Suzuki Motor Corporation is rich in story, but it didn’t begin its journey in the field of automotive. 

It was founded in 1909 and Suzuki began as an enterprise of weaving looms before it was transformed into the top automotive manufacturer it is today.

The company is known worldwide for its high-end motorbikes, automobiles 4WD, 4WD vehicles motors, wheelchairs along with internal combustion motors. 

With more than 133 distributors spread across 192 nations, Suzuki is currently one of the most profitable automakers in the world by its production.

Conclusion – Suzuki LTR 450 QuadRacer

The motivation behind the development of the LTR 450 is as noble as the car itself. 

Beyond developing an industry-leading ATV Suzuki’s goal is inclusion and bringing more people into racing by reducing the cost of buying an appropriate track-ready 4×4. 

Thanks to the enjoyment factor and ability to tear through the trails and jump high-height jumps it was difficult for novice recreational riders to refuse.

Despite its size, however, there are some who believe there is more to be gained from the LTR 450, even in its models post-2007. Some feel that its cost is expensive and is above what the average person is able to afford. 

Regarding its accessibility the quad is comparable to any other ATV which’s the impact on riding isn’t as significant as the manufacturer would like you to believe.

The questions are the same “Did Suzuki manage to create a best-in-class sports quad?”, “Did the sport riding community grow because of the QuadRacer’s existence?”. I’d think Suzuki did both.

How fast does a Suzuki LTR 450 go?

In stock form, the Suzuki LTR 450 top speed improved from 74 to 78 mph in its third year of production. This beats the YFZ450 by three mph. The speed rating is increased to 90 mph by putting the front sprocket 1 tooth ahead and adding a Yoshimura Cherry Bomb Chip and an open filter box lid.

Is the Suzuki LTR 450 good?

While the ltr is great for trails, I recommend that you use 22/20 tires, a 13t front sprocket, and a chassis with swingy skid plates. The narrow trails can make it difficult to use the width. You might be able to find someone who has one of each quad and ask them if they would let you test drive it and decide which one you like.

Why did Suzuki stop making the LTR 450?

After selling 25,396 units, Suzuki decided to stop importing the LT-R450 from Suzuki into the USA in 2009. The EPA fined Suzuki US$5,000 for emission control violations on the RMX450Z and the LT-R450.

What’s faster LTR 450 or YFZ 450?

The Yamaha YFZ450R has the fastest of the two. This is even after we took off the airbox lids to install the timing plug in the Suzuki. The YFZ is powerful and can be difficult to ride. The LT-R450 is smooth with the Dubach exhaust.

How do you check the oil on an LTR 450?

The correct method to test the level of oil would be by letting the motor run for around 3-4 minutes, at idle. Then turn it off and let it sit for a couple of minutes.

How fast does a Suzuki LTZ 250 go?

50-60 mph
In general, engine configurations contribute to the LTZ250’s top speed which is 50-60mph (80-96.6 kilometers/h) and 32.3 hp/32.7 PS (24.1 kW @ 4000 RPM) the power output advertised.

What quad size is for me?

For adults who are over 5’10” A smaller ATV (around 400cc) will be a good option unless you have particular reasons for wanting something with more power. If you’re taller we suggest looking at 500cc or more machines. For the best comfort on your bike, it is best to choose the right machine to fit your body.

How fast does a 450cc dirt bike go?

Typically, dirt bikes with engines of 450cc can achieve speeds of around 90mph. Keep in mind that this speed will be contingent upon other elements like the terrain.
