Suzuki Eiger 400 4×4 Specs and Review 2022

Suzuki Eiger 400: Suzuki is a master craftsman of outstanding off-road sport quads. 

Therefore, when something as simple as Suzuki’s Suzuki Eiger 400 4×4 comes on the scene, it cannot be avoided being lost in the crowd of rockstar race vehicles. 

Suzuki Eiger 400

This article highlights Suzuki’s infamous but reliable four-wheeler, which aims to shake up the image.

Its name is Suzuki Eiger 400. is a rec-utility automobile that was released to the general public in 2002. With a 376-cm3 engine, cable-actuated 2WD, and 4WD, and a traditional rugged appearance the dual-purpose machine has all the elements needed to offer simple, traditional enjoyment.

From the beginning, it was clear that the Eiger was unable to stand out from its popular counterparts – in spite of its focus on the rec-utility sub-segment. 

However, that didn’t hinder the series from releasing 25 models between 2002 and 2008. Wondering about getting your own Suzuki Eiger 400? Learn more about this small but highly praised vehicle.

Baptism Through Fire

There’s no better way than this section’s title to introduce the origins of Suzuki Eiger 400. 

The Eiger was first introduced to the public around the beginning of the millennium the 3-76-cm three-wheeled machine surpassed legendary legends like those of Suzuki KingQuad, LTZ400 Quad Sport, and the LTR 450 Quad Racer. 

While all of its predecessors are sport quads (which shouldn’t have been a factor) however, it was the time of its introduction that has made it the Suzuki Eiger and one of the least praised mid-sized ATVs Suzuki made. produced.

It may not have been in the eyes of consumers as the must-have vehicles until about halfway through the production phase. 

However, this vehicle was a beast with (and has) plenty to offer its users. The Eiger has a wealth of features ideal for cruising and outdoor pursuits. 

The most well-loved features are the ease of shifting the transmission, placement of levers and controls, easy access to engines and other mechanical components, and seamless engagement with 2WD/4WD. All that is highly valued by the test drivers and other enthusiasts.

Other useful features of the quad were:

  • High-radius fenders (great for taller tires).
  • A rugged-style grill.
  • Racks for utility (front as well as back).
  • Front bumpers are designed to allow for effortless winch (view on Amazon) installation.

The Eiger also offers durability and comfort that are ideal for all kinds of applications such as relaxing rides or work. 

With all of these features things in place, it was clear that lots of thought went into the design of the Eiger and its function. In the end, these features earned the big-bore machine its status as a rite of passage.

Price of a Suzuki Eiger 400

The cost for the Eiger 400 is $4,349 to $5,899 based upon trim, year as well as driveline option. 

The most affordable of the versions is 2003’s Suzuki Eiger LT F400K3 The most expensive model is an Eiger from 2007 LT -A400FHK7 (Advantage A400FHK7 (Advantage Camouflage).

It is interesting to note that the 4×4 trims are cheaper than the 2×4 models. The camo models didn’t differ in cost compared to the base models. This is a great deal for those who love the hunter-themed body panels.

Auction listings are quite scarce. If you do find one auction listing, they will usually be listed as Suzuki Eiger Quadrunners.

They are priced between $690-$3,550. They’re well-maintained, mostly used for ranch work in addition to off-pavement areas, and could include Suzuki Eiger parts like a tractor and the 25-gallon grass or the garden sprayer (view on Amazon) along with the addition of a wand. 

A few may have a brand new battery, a lockable top box or gun scabbards, or custom-designed padding for the shooting rail. 

Some may also have small cosmetic flaws or require painting. As is to be expected, second-hand Tigers are available online, but without titles.

Tires & Brakes

Quads made available in Australia included Dunlop tires and also those that are sold within the U.S., Canada, and Sweden equipped with all-terrain Maxxis rubber.

 Due to the fenders’ high radius, it’s a good idea to upgrade the stock rubber with bigger tires such as the Kenda K538 Executioner (view on Amazon) particularly when you intend to utilize your quad to do serious mudding.

Front Tire, off-road/road air pressure Dunlop KT121HD AT25 x 8-12, tubeless (P-24)
Maxxis M913S AT25 x 8-12, tubeless (Others)
Tire Pressure: 32.5 kPa (0.325 kg/cm2, 4.7 psi)
Rear Tire, off-road/road air pressure Dunlop KT405HD AT25 x 10-12, tubeless (P-24)

Tire Pressure: 30 kPa (0.30 kg/cm2, 4.4 psi)
Tire Tread Depth, F/R Limit: 4.0 mm (0.16 in)
Front Brake Type Disc brake, twin
Rear Brake Type Drum brake

Be sure to note the operating pressure that is permissible of your tires (whether new or stock). Don’t exceed an amount of 45kPa (0.46 kg/cm2, 6.5 psi) for the maximum pressure.

It’s 70 kPa (0.71 kg/cm2 10 psi) when filling them up, as well as 25 kPa (0.25 kg/cm2, 3.6 psi) when airing them down. Suzuki suggests using a manual air pump instead of an air compressor with high pressure to limit the damage caused by excessive inflation.


Inside the steel frame are two independent double-wishbone front suspensions as well as swingarm rear suspensions with two mono-shocks that provide 6.7 inches (170 millimeters) in wheel movement across all four wheels.

 The impressive ground clearance and the 50-inch wheelbase give the Eiger outstanding handling in any terrain.

Suzuki Eiger with manual transmissions that are sold across the U.S. and Canada tend to weigh more than models released from Australia or Sweden. 

It is interesting to note that the opposite is the case for their models with automatic transmissions. Despite the differences in dry weights, the models have the same capacity for load limit.

Setbacks and Solutions 2002 Recall

Suzuki has voluntarily recalled about 4,700 units of 2×4 and 4×4 automatic transmission Eiger 400 models due to crankshaft issues.

This decision was brought about by a manufacturing flaw in the quad, causing its crankshaft to break during operation and resulting in the vehicle quitting altogether (due to an interruption of power transfer).

A revamp in the design of later-year models permanently resolved this problem.

Overcharging Regulator

This issue has come up pretty frequently in forums and seems to be one of the chief consumer complaints about the quad.

While the reason is often a defective battery, the electronic accessories we put on our wheeler are also to blame.

Abnormal driving conditions may also lead to fluctuations in regulated voltage between the battery terminals.

As a best practice, ensure that aftermarket accessories you buy do not use excessive amounts of electricity.

Regularly inspect the state of your machine’s wire harness and test the contact between couplers. One-off instances may still point to a leaking battery.

But if you have cooked the acid out of batteries way too many times, the regulator/rectifier is definitely at fault.

Starter Motor Problems

Going straight for a CDI box replacement is not the best (nor the most practical) way to address a starting problem, as there is more than one aspect of the wheeler needing thorough inspection.

Gear selection and electrical components top the list. For beginner owners, it is crucial to note that starting the engine from any other transfer position apart from neutral is never going to work.

A blown fuse, shorted relays, or a low-voltage battery are likely to be problem sources too. I also recommend checking for a defective parking brake switch or starter clutch. If you are lucky, the culprit could simply be worn gaskets or a flawed gear selector.

Starting Difficulty

While the preceding issue leans toward an electrical fault, starting issues are almost always about your four-wheeler’s carburetor and air-fuel mixture.

Resolving this problem is both easy and challenging, as the remedy could go from cleaning clogged passages, filters, and fuel lines to replacing your entire top-end.

Upkeep of your weekend warrior should not only be based on manufacturer-recommended schedules but also on how often you ride your quad in the outdoors or how long you have it sitting unused in your garage.

These are only some of the known issues the Suzuki Eiger 400 has. If you are looking for a more extensive list of common problems and how to rectify them, Suzuki ATV forums and other similar off-roading sites are great resources.

About Suzuki

Suzuki Motor Corporation is a world-renowned corporation founded in 1909 that traces back its humble beginnings to weaving loom.

Decades after, it has ventured into the automotive industry and produced several ground-breaking vehicles – including the Suzuki Eiger 400 4×4.

Today, the Japanese company is recognized as one of the most successful automakers by production worldwide – with over 133 distributors in 192 countries and a myriad of product offerings ranging from automobiles and motor vehicles to internal combustion engines.

Conclusion – Suzuki Eiger 400 4×4 Review

Between the automatic and manual transmission models, experienced adventurers strongly recommend the latter. True, both versions boast torque-sensing front differentials, foot-operated brake pedals, selectable driveline modes, and impressive fuel consumption.

But going for the manual 4WD trims guarantee fewer engine problems, better maneuverability, and more leeway for project builds. Plus, a straight-axle rear suspension is always good to have on bumpy roads.

The attention it is now enjoying from the off-roading community may be late by a few decades – yes. But it does not make the Suzuki Eiger 400 less of a bulletproof machine. Nor does it make this rare gem less deserving.
