About the Suzuki LTZ 400

Prior to the introduction of the Yamaha YFZ450 and Suzuki’s own Quadracer 450R and the Suzuki LTZ400 ruled the sports segment. 

Also known as QuadSport Z400 it was a 4×4 with the fastest velocity of around 70mph. 

It was equipped with an aerodynamic tubular frame with adjustable shocks and an automatic gearbox with five speeds (including reverse gear). reverse gear). 

This LTZ 400 also had a high-clearance fender and bright yellow bodywork, which gave it the appearance of a great play-ride.

It was introduced to the market in 2003 The four-wheeler was one of the first vehicles that brought the 4×4 industry back to its former glory. 

It provided the ideal mix of the rider’s comfort, unrelenting performance, and excellent ergonomics in one package that could be used by those who are both competitive and recreational. 

With its laudable quality and handling characteristics, the vehicle was widely regarded as the most reliable vehicle for navigating dunes and trails in wooded areas and an impressive competitor in the 400-/450cc category.


The LTZ 400 saw very few improvements throughout its life most of them were cosmetic. 

The only performance-impacting upgrade it received was in its fuel system when Suzuki decided to give it fuel injection in 2009. 

The feature was well-loved by Suzuki’s loyal fans however, it proved to boost the quad’s sporty and bulletproof nature. 

The 450-class became the new kings of the track, and eventually, the end of the quad sports life in the year 2018.

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

The core of the LTZ 400 was loaned from the famous dual-purpose motorcycle that Suzuki’s DRZ400S. 

It is a 398-cm3, liquid-cooled 4-stroke DOHC engine (mated to a Mikuni BSR36 carb, and later, DFI(r)) with a counter-balancer, which gives sufficient power throughout the powerband, and more torque in low RPM levels.

Cylinders were built from aluminum alloy, which was then coated by Suzuki Composite Electrochemical Material (SCEM). 

This plating enabled better heat transfer and a tighter clearance from the cylinder to the piston, as well as forming a powerful combustion chamber. 

In addition, internal oil passageways in the cylinders decreased the weight of the vehicle and maintained the vehicle’s center of gravity at a low level.


One thing that set this LTZ 400 above its counterparts was the addition of a reverse gear within its five-speed gearbox.

This makes it a great vehicle to handle regardless of whether it was on forest trails or dirt roads.

 It also had a Raptor-like push-rod clutch system and shared the same shim-under-bucket-tappet valvetrain design with its parent DRZ400S.

Engine management on the LTZ400 was further enhanced by letting tires connect to provide better grip when it detected wheel slippage. 

While this added time dragged from the time it took to launch it also made it more steady and reliable throughout.


The LTZ400’s ECU used a 16-bit processor and the 96-kb ROM unit that was programmed to determine the best injector volume, injection rate, and ignition timings depending on the motor’s speed as well as throttle position, to mention some. 

The data collected from this system enhanced the vehicle’s traction as well as made it easier to start (especially when coupled to the engine’s auto compressor). 

An easy-to-maintain CDI system as well as a triple-phase generator power the machine along with all the other electronic components.

Tires & Brakes

The tire-wheel assembly was comprised of 20- and 22-inch both rear and front LTZ 400 tires that were mounted on alloy wheels made of aluminum (for less weight unsprung). 

Although this setup efficiently transferred force to ground conditions, the unit would be improved with Sand Gecko or GBC XC-Master ATV Bias Tires (view on Amazon) which significantly improve the efficiency and traction of linear motors. 

However, dual discs with hydraulics at the front and one hydraulic disc in the rear will suffice and give the quad plenty of stopping power.


The LTZ400 initially featured the look of a Raptor chassis but was later modified to a T-bone frame, with an updated sub-frame designed for later models. 

The new frame along with the adjustable shocks with rebound damping made it easier to move on the machine while driving with a high degree of force and also provided for an incredibly comfortable and soft ride while you are cruising.


Wheel travel remains an understatement in comparison to similar racing machines. Fortunately, adding longer axles, A-arms, as well as additional aftermarket shocks for the LTZ 400 as well as lowering the pressure of the springs can help enhance the quad’s handling as well as bump absorption. 

(Trivia Many racers believe that the shocks used on the LTZ 400 are the same shocks found in Honda 400EX). Honda 400EX).


It’s QuadSport Z400 shares its suspension elements and sizes with 400EX with the exception of its dry weight and a seat height that is slightly less than those of the latter. 

The overall dimensions that this model LTZ 400 make it perfect for sloping trails, MX tracks, and drag racing.

Exterior & Lighting

One of the QuadSport Z400‘s most useful and distinctive attributes is its sharp fenders, distinctive slim silhouette, and horizontally stacked headlights (taken from the Hayabusa 1300 sportbike) integrated into the front fender. 

These are not just a part of the appearance of the four-wheeler but also improve lighting distribution. 

An aftermarket graphics kit such as the Senge Graphics Kit (view on Amazon) will enhance the beauty of the design.

In addition to these features that remain unaltered The machine was subjected to several minor adjustments to Suzuki LTZ 400 parts such as footpegs, handlebars, and seats. 

The handlebar was reduced by 5 millimeters while the handlebar was it was angled 10 millimeters forward to make room for a more powerful riding position. 

The footpegs were also adjusted to fit the function of the bar. The seat, too, was slightly altered to match the style of the seat in the LTR 450, to provide more space for the rider and increase cornering performance – without sacrificing the rider’s comfort.

Cost of a Suzuki LTZ 400

Because of the importance that the Suzuki QuadSport Z400 has it can be difficult to locate a secondhand version online in good condition. 

But, pre-loved models of the LTZ400 maintain their value very well, with resales that are worth half of the original cost that the quad. 

Based on the type of fuel you prefer to use, system, you can look for earlier models or models from 2008 (carbureted) or models post-2009 (fuel-injected). Whatever you choose, you can expect the QuadSport to be priced in a range of $2,000 to $5,200.

Suzuki LTZ 400 Upgrades

Suzuki LTZ 400 Upgrades

For the typical person who doesn’t race but wishes to have the ability to compete The following modifications are almost essential:

  • Replace the cover for the water pump made of magnesium by using a cover from the 2003 or 2004 Suzuki LTZ 400.
  • Replace the coolant to avoid unwanted or premature excessive heat from the power mill.
  • Upgrade the exhaust system to boost the efficiency of the engine and reduce the consumption of fuel.
  • Install an air jet kit to improve the carburetor’s ability to deliver fuel (for models prior to 2009).
  • Replace the air filter to ensure that no particles into the intake system or get into the engine.


You can choose between either a slip-on or a full system when you upgrade the pipe. Choose the slip-on option if you’re more of an avid trail rider. A Highly advised LTZ 400 exhaust is the White Brothers E-series Pipe. 

The typical price for a slip-on is between $200 and $500. If you’d like your exhaust to do more than eliminate toxic fumes, going for the Yoshimura TRS system or Curtis Sparks full exhaust (view on Amazon) is the way to go. 

Installing either of these systems will give you greater engine performance and horsepower increases of around 11 percent. There is one drawback: the system may not fully complete its noise reduction function.

Jet Kit

If you’re not a racer in competition You may want to buy a few primary jets and pilot jets, and determine which ones are effective. 

If you decide to purchase a complete jet kit typically is for racers who utilize their LTZ 400s in drag races. Additionally, they’re usually dependent on the type of exhaust. 

Therefore, if you’ve no plans to upgrade the standard pipe, you might not be required to install jet kits. 

If you decide to, make sure to choose larger-sized main jets – this will solve the problem of leaky exhausts when the throttle is decelerating.

Air Filter

In the case of air filters, there are a lot of debates between K&N and Uni being the more superior brand. 

Although both do a decent job at preventing pollutants from reaching an engine, one is better than the other, based on the locations and operating conditions.

California people, for example, prefer an oil-based Uni foam filter instead of one made of the K&N version due to how fine dust particles are found in the state. 

In contrast, people who like regular repairs and want to improve the high performance of their vehicles, opt for the latter. 

The choice of the best filter is simply the matter of deciding which filter to use first or flow, and knowing that selecting one will compromise the other.

Modifications to Come!

These suggestions are fundamental modifications that you can apply to this quad, the LTZ 400. For more experienced owners who wish to unleash the maximum potential from their Quad, think about these suggestions:

  • 39-mm FCR carb/Quickshot3
  • The exhaust and BBK. Full HMF Competition series exhaust wrapped in DEI wrap
  • Intake update updates such as Honda 400ex intake tube with no airbox
  • Quad Tech radiator shrouds (view on Amazon)
  • 293/536 WebCam racing cams, or old-fashioned hot cams
  • Wiseco valves as well as a 94mm J&E piston
  • The Tokyomods Less Tension throttle Spring
  • Aftermarket rear linkage, with a 400EX front spring/boot or +1.25″ LSR swingarm
  • Elka Stage 3 shocks and a Hermann swingarm
  • Fox Float/Podium front and rear shocks the rear TCS shock
  • A little higher ITP GNCC wheels and tires with G-Force hubs
  • Steering stabilizer similar to the Houser Racing Bar anti-vibration clamp (view at Amazon)
  • In the case of Pro Armor or IMS-Roll, nerf bars shoepegs, and heel guards
  • Renthal McGrath Fatbar(r)
  • ASV unbreakable levers
  • A clutch lever from aftermarket and perch to replace the parking brake
  • Full-belly and skid plates on the rear bumper, full-belly, and grab bar

Certain of these suggested improvements will be canceled when you own an LTZ 400 from 2009. LTZ 400 or older version. For the 2009 QuadSport specifically, it was given a number of improvements derived from that season’s LTR 450. 

For example, the intake track and cam were changed to allow for greater airflow speed and, therefore, you’d only require a slip-on upgrade instead of an exhaust system.

In the end, you might be better off focusing on performance enhancements that enhance the suspension’s geometry and speed as test drivers have reported models from 2008 that launch better and move more quickly than LTZ400 models from 2009 and up.
