2005 ltz 400 top speed DEFAULT

The Suzuki LTZ 400 (QuadSport Z400) set the bar for present-day sport ATVs. It launched in the market following Suzuki’s decade-long sport quad stasis – making its release a much-anticipated one. With 400-cc racing machines at their peak in the early 2000s, there could not have been better timing to do so.

The Suzuki LTZ 400 (QuadSport Z400) was a high-performance quad that dominated the market segment between 2003 and 2018. Considered one of the best sport ATVs of all time, this machine featured aggressive bodywork, long-travel suspension, and a powerful 398-cc engine.

Apart from its excellent geometry and design, the LTZ 400 was also known for being the first four-wheeler to beat two-strokes at their own game in racing circuits and MX competitions. This is just one notable fact about the Suzuki LTZ 400. Continue reading to learn more about this classic racer.

About the Suzuki LTZ 400

Before the advent of the Yamaha YFZ450 and Suzuki’s own Quadracer 450R, the Suzuki LTZ400 ruled the sport segment. Otherwise known as the QuadSport Z400, this 4×4 boasted a top speed of 70 mph. It had a race-inspired tubular frame, modifiable shocks, and a 5-speed manual gearbox (including a reverse gear). The LTZ 400 also had a DRZ400-adopted power mill, high-clearance fenders, and bright yellow bodywork that made it look the part of a perfect play ride.

Introduced to the public in 2003, the four-wheeler was one of the first machines to bring the 4×4 sport industry back to life. It offered the perfect mix of rider comfort, unrelenting power, and excellent ergonomics in a single package that catered to both aggressive and recreational riders. Thanks to its praiseworthy qualities and handling manners, the machine was recognized as the go-to vehicle for traversing dunes and wooded trails and a formidable contender in the 400-/450-cc category.


The LTZ 400 saw very few upgrades during its lifetime – many of which were cosmetic. The only performance-impacting upgrade it received was in its fuel system when Suzuki decided to give it fuel injection in 2009. This new feature was welcomed by Suzuki’s loyal following, nonetheless, and proved to enhance the machine’s bulletproof and sporty nature. The 450-class emerged as the new kings on the racetracks, eventually leading to the QuadSport’s end of life in 2018.

Suzuki LTZ 400 Specs & Features (2003 Suzuki LTZ 400)


The heart of the LTZ 400 was loaned from the famous dual-purpose motorcycle, the Suzuki DRZ400S. The said motor is a 398-cm3, liquid-cooled 4-stroke DOHC engine (mated to a Mikuni BSR36 carb and, later on, DFI®) with a counter-balancer that offers usable power across the powerband and increased torque in the lower RPM ranges.

Cylinders were made of aluminum alloy and plated with Suzuki Composite Electrochemical Material (SCEM). This plating made for better heat transfer and tighter piston-to-cylinder clearance while forming a more efficient combustion chamber. Furthermore, internal oil passages in the cylinders reduced the vehicle’s weight and kept its center of gravity low.


One of the things that put the LTZ 400 above its counterparts was the inclusion of a reverse gear in its 5-speed gearbox, which lends to its superb handling, whether on forest trails or dirt tracks. It also had a Raptor-like push-rod clutch system and shared the same shim-under-bucket-tappet valvetrain design with its parent DRZ400S.

The engine management system in the LTZ400 was further improved by letting the tires hook up for better grip when it sensed wheel slippage. While this enhancement chipped away from the quad’s launch time, it did make the machine more stable and predictable all around.


The LTZ400’s ECU utilized a 16-bit CPU and a 96-kb ROM unit programmed to select the optimum injection volume, injection, and ignition timing based on the engine’s RPM and throttle position – to name a few. In turn, data gathered from this system improved the vehicle’s traction and made for convenient starting (especially when mated to the engine’s automatic decompression system). A maintenance-free CDI system and triple-phase generator powers the machine and all other electronic accessories.

Tires & Brakes

Its tire-and-wheel assembly consisted of 22- and 20-inch front and rear LTZ 400 tires mounted on aluminum alloy wheels (for reduced unsprung weight). While this assembly efficiently delivered power to the ground, it could do better with Sand Gecko or GBC XC-Master ATV Bias Tires (view on Amazon), significantly improving traction and usability of linear power. Conversely, dual hydraulic discs at the front and a single hydraulic disc at the rear are plenty enough and provide the quad ample stopping power.


The LTZ400 initially had a Raptor-like chassis, which was later changed to a T-bone frame with a redesigned sub-frame for later-year models. This change in framework, coupled with rebound damping adjustable shocks, allowed for easier movement on the machine when riding aggressively and made for a plush, comfortable ride when cruising.

Wheel travel is still on the conservative side when compared to other same-class racing machines. Thankfully, adding longer axles, A-arms, and aftermarket shocks to the LTZ 400 and backing off the spring pressure help improve the quad’s handling and bump absorption. (Trivia: Many racing enthusiasts speculate that the shocks on the LTZ 400 are the same shocks used on the Honda 400EX).


The QuadSport Z400 shares suspension components and dimensions with the 400EX – except for its dry mass and seat height, which are slightly lower than that of the latter. Overall, the size of the LTZ 400 makes it perfect for twisty trails, MX tracks, and drag races.

Exterior & Lighting

Among the QuadSport Z400’s most practical and unique features are its sharp fenders, signature slim design, and vertically stacked multi-reflector headlights (taken from the Hayabusa 1300 sportbike) integrated into its front fender. The latter not only add to the four-wheeler’s styling but also provides better light distribution. An aftermarket graphics kit like Senge Graphics Kit (view on Amazon) will help enhance the raciness of its aesthetics.

Outside of these untouched features, the machine underwent several minor changes to some Suzuki LTZ 400 parts such as handlebars, footpegs, and seats. The handlebar was lowered by 5 millimeters and angled forward by 10 millimeters to accommodate a more charging rider position. Footpegs were also tweaked to match the purpose of the handlebar. Similarly, the seat was slightly modified to match the seat style found on the LTR 450, make more room for the rider, and improve cornering – without compromising comfort.

Cost of a Suzuki LTZ 400

Because of the value of the Suzuki QuadSport Z400, it can sometimes prove challenging to find a secondhand unit online that is in mint condition. Nevertheless, pre-loved LTZ400s keep their value quite well, with resale units worth half the original list price of the quad. Depending on your preferred fuel system, you can scout for 2008 or earlier models (carbureted) or post-2009 ones (fuel-injected). Either way, expect the QuadSport to have a pricing average falling between $2,000 and $5,200.

Here is a non-exhaustive pricing table for those of you wondering about LTZ 400 MSRPs. Note that this rundown only covers from 2003 to 2014. (Source: Nada Guides):

Suzuki LTZ 400 Upgrades

For the average person who does not race but would like to have the ability to do so, the following mods are almost a necessity:

  • Replace the magnesium water pump cover with one from a 2003 or 2004 Suzuki LTZ 400.
  • Swap out the coolant to prevent premature or unwanted overheating of the power mill.
  • Upgrade the stock exhaust system to improve engine performance and fuel consumption.
  • Install a jet kit to enhance the carburetor’s fuel delivery (for pre-2009 models).
  • Change the air filter to ensure no pollutants enter clog the intake or enter the engine.


You may choose between a slip-on or a full system when upgrading the pipe. Go for the slip-on if you are more of a trail rider – a highly recommended LTZ 400 exhaust is the White Brothers E-series Pipe. Generally, slip-ons cost anywhere from $200 to $500. But if you want your exhaust to do more than just remove toxic fumes, opting for a Yoshimura TRS or Curtis Sparks full exhaust (view on Amazon) will be the route to go. Equipping your vehicle with either system allows better engine performance and horsepower gains by at least 11%. The only setback is that either system does not quite fulfill its noise control function.

Jet Kit

If you are not a competition racer, you may want to purchase a few main jets and pilot jets and test which ones work. Going for a full-blown jet kit usually pans out for riders who use their LTZ 400s for drag races. Besides, they are usually dependent on one’s choice of exhaust. So, if you have no intentions of upgrading the stock pipe, you may not need to install a jet kit. But if you do, go for a bigger-size main jet – this solves problems with slip-on exhausts crackling when the throttle decelerates.

Air Filter

As for air filters, there are many contestations between K&N and Uni being the better brand. While both do a good job of blocking pollutants from getting through to the engine, one outperforms the other depending on location and riding conditions. California residents, for instance, prefer an oiled Uni foam filter over a K&N variant due to how fine dust particles are in the state. Meanwhile, riders who are comfortable with frequent rebuilds and are after vehicle performance go for the latter. Choosing the better filter is essentially a matter of prioritizing filtering or flow – and knowing that picking one of the two would mean compromising the other.

Further Mods

The above suggestions are basic mods you can do on the LTZ 400 QuadSport. For more mechanically savvy owners who want to bring out the full potential of their quad, consider the items below:

  • 39-mm FCR carb/Quickshot3
  • BBK and exhaust, Full HMF Competition series exhaust wrapped with DEI wrap
  • Intake updates like Honda 400ex intake tube, no airbox
  • Quad Tech radiator shrouds (view on Amazon)
  • 293/536 WebCam racing cams or old-style hot cams
  • Wiseco valves and 94-mm J&E piston
  • Tokyomods Less Tension throttle spring
  • Aftermarket rear linkage with a 400EX rear spring/boot or +1.25″ LSR swingarm
  • Elka Stage 3 shocks and a Hermann swingarm
  • Fox Float/Podium front shocks, TCS MX rear shock
  • Slightly taller ITP GNCC tires and G-Force wheel hubs
  • Steering stabilizer like Houser Racing Bar Anti-vibration Clamp (view on Amazon)
  • IMS-Roll or Pro Armor nerf bars, footpegs, and heel guards
  • Renthal McGrath Fatbar®
  • ASV unbreakable levers
  • An aftermarket clutch lever and perch replacing the parking brake
  • Full-belly and rear skid plates, bumper, and grab bar

Some of these recommended upgrades will cancel out if you own a 2009 LTZ 400 or a more recent model. For the ’09 QuadSport specifically, it received a lot of updates lifted from that year’s LTR 450. For instance, its intake tract and cam were reshaped for higher airflow velocity – hence, you would only need a slip-on upgrade instead of a full exhaust system.

If anything, you may want to concentrate on performance upgrades that will improve suspension geometry and acceleration, as test riders have attested to pre-2008 models launching better and pulling ahead faster than 2009-and-up LTZ400 versions.

    The kfx must be an 05 or 06 then, and the Z is an 04 or 03 model. Because anything that was done the Z was done with the kfx. Even eith the bigger carb, it will be a barely marginal race. Depends on the riders weight, shifting revs, and who gets the hole shot.

    I know it sounds trivial, but tire pressure might have something to do with that. Are you talking drag or top speed?

    Suzuki did bump up the cam in 06 and Kawi left it the same as the 05. Break in of the engine has alot to do with how well an engine runs also.

    like said before, the years are different! in 03 and 04 it stayed the same mechanical weise. in 05 and 06 they put on bigger carbs, better shocks and a newer style swinger(also found on the 04) overall it is the same quad minus color. on the kawasakis frame it even says MADE BY SUZUKI. if that isnt enough for you start tearing into the motor, im sure youll find similarities.

Suzuki LTZ 400 Specs – Value, Weight, Oil and Top Speed | ATV Style

Suzuki’s Z400 ATV, also known as the LTZ-400, is a high performance all-terrain vehicle in Suzuki’s popular Quadsport ATV lineup. The Suzuki Z400 earned it’s reputation of being an all-around top performer by being equally impressive on trails, sand dunes and on the race track. The Z400 provides ample four-wheel fun for the experienced rider.

Key features of the Suzuki Quadsport z400 include aggressive bodywork with high fenders and specially designed air intake vents to improve airflow to the radiator. The Suzuki 400 ATV also sported a distinctive color pattern, blue and yellow (white also available), and a lot of optional high performance aftermarket Z400 parts were available.

From the Z400’s compact lightweight 398cc 4-stroke, single-cylinder, liquid-cooled engine to it’s lightweight, high tensile steel-alloy frame and removable steel sub-frame this Suzuki ATV screams of fun.

The Suzuki QuadSport Z400 all-terrain vehicle is manufactured by Suzuki and is designed for riders 16 years of age or older. In 2014 Suzuki quietly discontinued production of Suzuki Z400 ATVs. It is apparent that the mass appeal of side by side ATVs and utility ATVs has led to the decline in demand for sport ATVs.

How fast is the Suzuki LTZ-400?

Suzuki z400 top speed is 70 MPH. Higher speeds can be attained after installing high performance parts however 70 MPH is the stock speed rating. Several factors greatly affect speed such as condition and tuning of the engine, altitude and wind conditions.

Suzuki believes strongly in safety and offers to pay for rider training courses to anyone 16 years or older wanting to take them. They refer riders to a local Suzuki dealer and arrange for the classes to be taken, very few other types of products can say that about a manufacturer. Of all the ATV brands, Suzuki is a leader in being proactive about safety.

What kind of oil does the LTZ-400 use?

The LTZ-400 ATV requires 2.2 quarts of 10w40 engine oil. Some manufacturer data sheets specify 0w40 which works just as well but the general consensus is that, in warmer climates especially, 10w40 is the way to go. Fully synthetic oil is not required unless high performance parts have upgraded the power output of your z400 or if it has already switched to synthetic. Once a change to synthetic is made it’s not recommended that you alternate back to regular oil.

How much is a used z400 worth?

ATV value is dependent on condition, age and upgrades if any. z400 MSRP averaged $5200 new and a used z400 will be worth roughly half of that or less, unless it’s been exceptionally maintained and upgraded. If you want to valuate your z400 for sale purposes you can read more about ATV values.

Will Suzuki ever produce another Z400 model? They haven’t said they wouldn’t but it will depend on market demand. I hope you found this Suzuki LTZ-400 quad review helpful.

How much Does a Suzuki LTZ 400 Weigh?

The Suzuki LTZ 400 all-terrain vehicle weighs 372 lbs (168.7 kg) dry. ATV dry weight means the weight of an ATV without fluids, such as gasoline, cargo or riders added.

Suzuki Z400 Parts Availability

Several marketplaces carry z400 quad parts. We’ve found a great selection online, at fair prices, new from motosport.com and used on ebay.com.

    Everyones numbers are right about dead on. If you put in the gearing according to the gearing/speed calculator here: http://home.earthlink.net/~gellett/ltz400.htm
    It's right on. I went to a 39t rear sprocket and I top out at 67 mph on the flat and 69.5 downhill. I weigh about 180 and all I've done to the machine is dynojets, airbox lid removal, and removed the endcap.

    I threw on a set of 22" ITP Blackwaters on 8" steel rims (heavier than the stock 20's by quite a bit). After dropping one tooth on the front sprocket I'm hitting 65 on the flat and 67 on the downhill. The increased ground clearance is well worth the reduced top speed.

Fucked me in all holes, bitch. Then I ended up all over again, like a youngster. Why as a youngster. When I was 18 years old, I finished five times a day, you know this when the pussy is constantly flowing and. You want to fuck, it is impossible to sit in class when you can even stick your whole hand in there.

I feel that I was annoyed again, bent down, dropped down on my elbows, buried myself in the pillow, embracing her, straight, as if at all, only now I. Still had my dust in the pop. I moved the member a little deeper, about half the barrel went inside and stopped, waiting for the reaction. But Irka was silent, continuing to cheer.

And I slowly walked to the stop, pulling a finger out of her ass.
