How Fast Does a Suzuki LTR 450 Go?

Sport ATVs like Suzuki LTR 450 are among the best made. In the early 2000s, this purpose-built ATV with a 450-cc RM-Z450 engine, sturdy chassis, outstanding suspension, and aggressive style rallied authentic sport ATVs. Smaller-displacement, but groundbreaking LT250R’s successor couldn’t have done better. The LTR 450, like its twin, has a slew of awards and award-winning features to its name.

Even more critically, though, it effectively expanded the sport riding niche that its ancestor pioneered over four decades ago. Aside from Dustin Widmer’s ATV Pro MX success, the 2006 LTR has positioned itself as the dominant vehicle in the motocross & GNCC racing worlds since its inception. Both Widmer and the custom-built vehicle have won back-to-back titles in the series above from the beginning. In this article, we will acknowledge everything regarding Suzuki LTR 450.

How Fast Does a Suzuki LTR 450 Go?

The Suzuki LTR 450 has a top speed of 74-78 mph. In its 3rd year of production, the Suzuki LTR 450 improved its speed by 3 mph.

This year, Suzuki’s LTR 450 peak speed increased from 74 – 78 miles per hour, outpacing Yamaha’s LZ450 by 3 miles. Installing a Yoshimura Cherry Bomb chip and an open filter box lid to the front sprocket increases the speed rating to 90 mph. Riders who have put the Suzuki LT-R450 through its paces can vouch for its abilities on various terrains, including woodland trails, mud pits, and steep inclines.

Despite its brand new status, this is achievable because of the machine’s powerful 4-stroke fuel-injected RM-Z450 engine and long-travel suspension. As a result, it does not create sudden bursts of power, unlike its competitors. Despite this, the front end can rise off the ground owing to its excellent throttle response.

The Quad Racer has a lot more going for it than just brute might. Several stock sport ATVs claim to be distinctive or unusual, but just one, the LTR 450, defied the stereotypes of its day. Race-ready without pricey chassis and suspension upgrades and other aftermarket bolt-on components. We would propose a Yoshimura Cherry Bomb, Yoshimura Nerf bars, and an on/off button for cosmetic reasons (or rider preference) rather than performance enhancement.

How Much Horsepower Does a Suzuki LTR 450 Have?

The Suzuki LTR 450 has 41 horsepower. With just 369 lbs, the Suzuki LTR 450 is swift for an average rider.

This 2006-2008 Suzuki LTR 450 Quad Racer is designed from the ground up to be a race-ready factory hotrod. It’s no different today. Motocross Champion Doug Gust and Suzuki engineers collaborated on creating a powerful, track-ready quad that was predictable and comfortable to ride. Front and rear suspensions were utterly adjustable, allowing the rider to fine-tune it to their weight and the track conditions.

The engine and center-of-gravity were maintained low using a unique lightweight frame. Fuel injection and 41 screaming horsepower were among the race-inspired, 450-cc engine features. Nevertheless, the Suzuki Quad Racer LTR450 is quick enough for the typical rider despite its lightweight 368 lbs (dry). The K&N 57-1128 FIPK Performance Air Intake System, on the other hand, may boost your quad’s performance by about 2.7 horsepower and make it more competitive on the track.

The K&N 57-1128 FIPK Performance Intake System gives the engine a more direct airflow channel to recover some lost horsepower’s. The throttle body is directly linked to the enlarged K&N high-flow air filter using a more extensive, aerodynamic HDPE intake tube. It ensures that the 450cc cylinder receives a steady supply of fresh air without navigating a series of twists. The factory air box is replaced with a robust powder-coated heat barrier, which keeps heated engine air out of the intake system. In addition, you may rapidly clean reusable gauze air filters to ensure optimal airflow after a race.

What is a 2007 LTR 450 Worth?

The average price of 2007 LTR 450 is worth $7,399. Therefore, the retail price of 2007 LTR 450 is $3,870.

Auction bids for the LTR 450 range from $1,500 to more than $12,800 based on the model year or trim level. An average of $4,500 is paid for a used car with many add-ons or aftermarket items. For example, Nerf bars, heel and frame protectors, Pro taper fat bars, custom graphics, or a custom-made graphics package are included in the price of near-mint units. Not only that, but several previously-owned LTRs have been powder-coated and are now street-legal.

In addition to the 2006 and 2009 versions, a few 2007 LTR 450s with Champion Yellow and White are for sale. The ’07 QuadRacers appear to be the most cost-effective option among the others. Unlike most sports ATVs, these vehicles aren’t hard to come by. A well-maintained quad may be yours if you know where to look and have the money to invest. Suzuki’s LTR 450 is easy to service, despite its electronic fuel injection and an electric start system. As simple as filling up the gas tank, performing routine oil changes and chain adjustments requires a few essential tools and your trusty repair handbook.

Why Did Suzuki Quit Making the LTR 450?

The EPA Authorities concluded that the LTR 450 doesn’t fulfill EPA emission regulations. Thus Suzuki quit making the ltr 450.

For the time being, Suzuki has said that they will no longer be producing the vehicle, citing EPA regulations that are becoming more rigorous. Although this theory has some merit, we believe that the economy significantly impacted this tragic circumstance. Once Suzuki first debuted the Quad racer 450 in 2006, the economy was robust enough to allow yearly improvements. Unfortunately, during this time, as the OEM 450 race machine movement was gaining strength, the economy began to sink in 2008.

To begin with, there was no longer an annual upgrade, and it now looks the actual cessation of models is a legitimate issue as a result. For example, consider the following: There were just a few new Suzuki LTRs imported to the US in 2011 although they were still 2009s. So it’s no surprise that the LT450R was dropped from the line in 2012 due to a lack of inventory, stricter lending conditions, and EPA issues. For those who want Suzuki back in this class, the Zook crew has options other than a total model redesign or further limiting the machine’s capability, such as exclusively selling the ATV like a closed-circuit race vehicle.

Does Suzuki LTR 450 Have Reverse?

No, the Suzuki LTR 450 does not have reverse.

Suzuki’s “ECM Logics System” keeps track of the pace at which the throttle and engine RPMs are being pressed. Another function of the system is to determine how quickly a rider is reacting so that it may change the amount of traction control spray that is used. Improved handling resulted from the additional control provided by the somewhat higher tires.

When designing the LTR 450 in 2006, Doug Gust provided feedback on the riding posture, which is highly developed and based on his comments. The 46-mm serrated footpads, conventional T-shape seat, and handlebars establish an excellent connection, mimicking the riding style of a professional racer. You can’t go wrong with a Champion Yellow and White option for the overall look. Suzuki included All-black wheels, chassis, and bodywork with red graphics on the Limited Edition version of the 2008 Suzuki LT-R450.

How Many Gears Does an LTR 450 Have?

Suzuki LTR 450 has 5 gears.

A manual 5-speed gearboxes return mechanism and a wet, multi-plate clutch unit send power to the wheels. Wheelspin is handled by an RK 520SMOZ10S O-ring chain (96 links + joint). A Yoshimura Cherry Bomb fuel injection re-mapping improves the quad’s power delivery. To get the most out of this component, you need to upgrade to a 12-tooth front sprocket, which boosts low-end oomph and enhances ground clearance without compromising performance.

What Kind of Oil Does an LTR 450 Take?

Suzuki LT-450 takes AMSOIL synthetic oil. AMSOIL synthetic oil can withstand high temperatures and stress from intense riding. In addition, they extend the lifespan of the Suzuki LT-450 by providing superior damage prevention and engine cleaning.

With a 42-mm throttle body, the Suzuki LTR 450 has a multi-hole injector for fuel injection. 10 liters/2.6 US-gallons of unleaded gasoline (RON 90 or above) with no more than 5 percent by weight (MBTE), 10 percent by volume (ethanol), or 5 percent by weight (methanol) in it, plus a 5 liter/2.6 US-gallons of the reserve.

It has a rigid polyurethane air filter and a dry-sump lubrication system. The new lubricating system has two feed pumps and is unique. The transmission is supplied by one pump while a scavenging pump nourishes the crankshaft and other components of the engine. Two independent feed pumps make the LTR 450’s crankcases more compact while increasing the shifting & clutch feel of the motorcycle.

In contrast, the oil capacities are 1.2 L/1.3 &1.4 L/1.5 US quarts. SAE 10W-40 Suzuki Quality 4-stroke oil in API grade SJ+ meets JASO T903 MA criteria and is recommended by the manufacturer. Other viscosity classes, such as SAE 10W-30 and 20W-50, may be used depending on the ambient temperature.

How Much Oil Do I Put in My LTR 450?

Its recommended to put 1200ml oil in the tank and 400ml oil in the engine.

Dyno testing showed an estimated boost of 2.74 horsepower & 2.17 ft-lb of torque when K&N fitted 57-1128 on an unmodified 2008 Suzuki LTR450. It also increased throttle response & engine loudness with an extra air intake. However, the mileage, modifications, & condition of your Suzuki LT-R450 Quad Racer may impact your unique findings.

The K&N 57-1128 FIPK Performance Intake System may transform your 2006-2008 Suzuki LTR 450 Quad Racer from a Quad Racer into a Quad Winner by removing nearly all airflow constraints.

How Do You Change the Oil in an LTR 450?

You can change the oil in a Suzuki LTR 450 via the Oil drip pan method.

Warm up the oil by running the engine for five minutes. Drain the engine’s coolant into a pan beneath the pan. Remove the oil tank bolt and the two massive case bolts using a wrench. 15 minutes of drain time is recommended. Be careful to avoid stripping the threads on the two bolts or the oil tank bolt. Because the threads on the oil tank are so tiny, you mustn’t overtighten the plug.

Use a wrench to pry off the oil filter cap. Take off the cover and spring before the filter is lowered into place. After the filter and spring have been installed, you may place them on the lid. With the wrench, make sure it’s snug. 400 milliliters should go into the clutch housing, and 1400 milliliters should go into the oil tank. Allow the engine to run for five minutes before turning it off. Then, please turn it off and measure the voltage. The dipstick should not be threaded into the cap but should be dropped back down to the bottom of the lid and then removed to verify. Add more oil as needed.

How Do You Change the Oil in Suzuki Outboard Motor?

You should set the outboard motor’s trim to the lowest position when installed. Tilt the engine to its bottom if the motor has only an engine mount adjustment. Use an adaptor to attach a garden hose to the base unit’s inlet nozzle port if it has one. If your engine doesn’t have an inlet port, but the lower part in a 45-gallon barrel of water. Until the engine reaches the optimum operating temperature, you should start the vehicle. Then, get out of the car and turn off the engine.

Keep an eye on the top cowl cover of your engine. There should be a way to keep it safe if something happens. Use a socket and a wrench if it has bolts. Please ignore it. Your owner’s manual should provide information on where to find the oil drain stopper and oil filter. It may see this on the right-hand side of the vast engines if you’re looking at them from the boat’s bow. Next, the Allen wrench socket, extension, & ratchet are required to remove the top unit side case. The side case is taking up too much of your time! Next, remove the dipstick from the top of the engine.

The bottom of the upper engine block has an Allen socket plug for the oil drain. White paint is frequently used to conceal it. You may use a ratchet and an Allen socket to unscrew it counterclockwise. It’s good to have an oil drain pan beneath the oil line. Let the water drain entirely for at least five minutes. Replacement of drain plug gaskets washer and hand screwing of the Allen socket plug back into the block is recommended.

Tighten it using the Allen socket and wrench. Oil filter wrenches are needed to remove the filter. Place the oil pan underneath to catch dribbles. When installing an oil filter, add some remaining oil to the gasket before screwing on the new one. Hand tighten it until it’s snug, but don’t overdo it.

Using the dipstick opening as a funnel, fill the engine with coolant. See your owner’s guide to figure out how much engine oil to put in your car. Some massive twin engines require as much as 5 quarts of oil for a first fill. Remove the dipstick and replace it upon filling the quarts to the brim. Put the key to begin the vehicle. Permit it to run in the background for many minutes. Turn ignition off with the key removed. You may clean the dipstick by removing it and wiping it down with a cloth. Insert the dipstick to check the oil level. Use this amount to fill the crankcase.

Dip the end of the dipstick into the water. Make sure you take off the engine side case and the fasteners that secure it to the vehicle. Use an Allen wrench and socket to tighten the mounting nuts to secure the bracket. After making sure the rubber gasket on the top of the case is in place, replace it. Tighten the fasteners to hold the top casing by hand or socket.

Is a 2006 LTR 450 Fuel Injected?

Yes, the 2006 LTR 450 Is Fuel Injected. a 2006 LTR 450 features a 450cc four-stroke engine and Suzuki electronic fuel injection.

Air acts as a catalyst during the combustion process, essential for an engine’s ability to burn fuel and generate power. A restrictive paper air filter and small tubes route the air into the throttle body through the original intake system. Air gets heated up and loses part of its ability to burn when driven around acute bends, across uneven surfaces, or into different-sized tubes.

The Suzuki 450’s inlet air temperature sensor fits into a connection on the rear of the heat shield to help with installation and make the K&N 57-Series FIPK Performance Intake System legal in all 50 states. Additionally, the intake tube has a fitting for the crankcase vent hose. You may install this FIPK intake system in about 90 minutes because no sensor adjustments are required.

How Wide is an LTR 450?

The LTR 450 is 1,245 mm in width. The 49-inch width of the vehicle avoids the need for aftermarket Suzuki LTR 450 A-arms. But it does not make the car an excellent choice for riding on narrow, curvy paths. On the other hand, plastic skid plates and puncture-resistant tyres from stock motocross-style tyres work excellently in woodlands and are easy to maintain.

To put it simply, the LTR 450 has an overall length of 72.6 inches (1,845 millimeters) and a width of 49 inches (1,245 millimeters). 1,045 mm (41.1 inches) is the front track and 985 mm (388.8 inches) is the rear track. Therefore, medium-sized to taller riders may find the seat height of 30.7 inches appropriate (780 millimeters). In terms of dry weight, the YFZ450 is marginally heavier than its Honda TRX 450R & Yamaha YFZ450 rivals.

The LTR 450’s frame is high-strength steel, contributing to the bike’s dry weight. Suzuki chose to maintain it the same despite market trends and not transition to an aluminum structure. The back fender bracing and brake pedal were aluminum/forged aluminum, not the chassis. Magnesium alloy was also used for the magneto and clutch outer covers, contributing to their reduced weight. In addition, the machine’s cylinder bore has been coated with a nickel-phosphorus-silicon-carbide coating to reduce weight. As a result of its reduced weight, SCEM plating is more efficient at transferring heat, has a smaller piston-to-cylinder clearance, and reduces wear.

How Much Does a 2006 LTR 450 Weigh?

The weight of the 2006 LTR 450 is 368 lbs or 167 kg. The maximum amount of weight is contributed by the frame of the vehicle.

Among the LTR 450’s dry weight contributing factors is its frame, which is made of high-tensile steel. Suzuki chose to maintain it the same despite market trends and not transition to an aluminum structure. The back fender bracing and brake pedal were aluminum/forged aluminum, not the chassis.

The lightweight magnesium alloy used for the outer clutch & magneto covers also contributed to the overall weight reduction. Weight-saving measures include nickel-phosphorus-silicon-carbide plating on the machine’s cylinder bore. The lighter SCEM plating contributes to more excellent heat transmission, closer piston-to-cylinder clearance, and increased wear reduction.


The Suzuki LTR 450’s manufacturing intention is noble as its design. Rather than just making a top-of-the-line ATV, Suzuki wants to make racing accessible to the masses by lowering the price of an entry-level 4×4. Even the most hesitant recreational riders couldn’t say no to the machine’s enjoyment factor and its ability to tear through tracks and precise sky-high jumps. However, those riders still believe that the LTR 450 has more to offer than its reputation would lead you to believe.

Even for those who can afford to pay for it, its cost is still prohibitive for most people. In addition, the quad hasn’t much of an impact on sports riding on other ATVs, which makes it comparable to other sports ATVs in terms of accessibility. We hope you must have acknowledged everything about Suzuki LTR 450 Go.
