Playmate of the Year — The LTZ 400

We’re always happy to to the track on an ATV built for racing. The handling, and power from the racers on the market today was a distant dream a decade Like most ATV owners, of our riding is on the trails and in the woods and that’s not always the best for a high strung racer, suited to rocketing corner to and between jumps than through the trees or gliding the dunes.

Championship winning does not often translate to all day play riding, but we’ve one sport ATV that bridges the gap

History Lesson

When the LTZ 400 was released it marked a watershed in sport ATVs. The new Suzuki quad came with a water cooled 4 … a high strength steel race inspired styling, and an stance and riding style. It … any obstacle on the track or ride the trails all weekend equal ease, and it was exactly a rapidly expanding sport and racing market had been for.

The new ‘Z offered handling, and performance never seen on a sport atv, it an instant hit, and it rapidly its only rival at the time, the TRX 400EX. Within weeks of its there was a yellow wave of new taking every riding and race track by storm. again Suzuki had released a that changed the sport, and the LTZ 400 supreme.

When Suzuki released the sharp, pro class level LTR 450 a few years later, the LTZ took a seat to it’s honed for the big brother. The old saying racing the breed was not lost on the Suzuki however, and lessons learned on the were soon to be incorporated in the generation LTZ 400.

Second ‘Z 400

Good Looks Great Feel

As with things in life, looks are and the LTZ 400 is no red headed stepchild. (No offense to who are!) The LTZ 400 looks GREAT! sporty, strong, and the body hints at the performance within. the perfect compliment to the LTR 450, and we wait to climb aboard!

always careful to check the and bodywork for any little edges or tabs that catch gear when riding, and happy to report the Suzuki had of the sort. It’s clear the was meant for aggressive action, and the sits in a “charging” position, a bar position designed to help better arm leverage, exactly as a ATV should. The foot pegs are placed, and at 46mms wide, are the size as on the LTR 450.

Also just like the the ‘Z gets Suzuki’s T-bone seat, which is for moving your body on during aggressive riding and Ahead of the steering column is a panel with a few warning and lights, and just in front of right knee is an easy to use lever. Finally, the front lever is also adjustable like on the LTR 450 as well.

Power to

The LTZ engine is a thoroughly modern, cooled, 398cc 4-…, dual overhead cam engine a counter-balancer. To keep things on all day trail rides Suzuki the ‘Z a large capacity with an “on-demand” thermostatically fan for consistent operating temperature, and once in a while you will it kick on. The bottom end of the engine a dry-sump lubrication system an oil reservoir mounted just of the engine, and a 5 speed gearbox reverse) to get everything rolling.

Fuel Injection is perhaps the thing to happen to ATVs they added a fourth (Also a Suzuki idea) The LTZ 400 is with Suzuki’s EFI system a 36mm throttle body and injector that delivers the mix in an efficient fine-mist spray Believe it or not, the pattern and of holes, and even the injector angle makes a big difference in how an EFI system delivers fuel to the and how well it runs.

Suzuki even straightened and the intake tract on the ‘Z for airflow velocity and the cam was reshaped for low to mid range power. A 16-bit CPU the injection timing and based on position, engine rpm, crank position, and other feeds in just enough The Suzuki system does one added twist in that it a little like a traction system, limiting fuel when it senses very changes in RPMs — the sign of wheel slip.

A of the key kicked the electronic fuel system on, and a stab at the starter brought the LTZ 400 engine to life. The starts very easily and we like the sound from the system which gives a rumble that sounds like the LTR 450. Suzuki the exhaust for better low to mid range and a drop of our foot brought the smoothly into gear.

We off!

The ‘Z runs and crisp throughout the power thanks to the EFI, and rather spinning the wheels it hooks up and you forward. The engine lets you it is all business, and the pull continues right off the bottom until into the mid range. All the power in the means nothing without an capable suspension however, and for Suzuki again turned to the learned on the track.

Suspension School

Years of and information gleaned from hours testing with of the best riders on the planet Suzuki engineers a very idea of what the LTZ 400 needed for It would be not much different its racy brother the LTR 450, but a more forgiving for new or less riders.

The front of the ‘Z dual A-arms with adjustable, piggyback reservoir-style that provide 8.5 in. of wheel Front shocks and springs designed for a softer initial that becomes firmer the suspension …, and we found to be adequate, but neither outstanding or off. In reality, all the manufacturers are to design a suspension package works adequately for riders of all and skill levels, and widely terrain.

There are just too variables to dial it in perfectly for but the ‘Z 400 shocks are far better some competing units, and work for many.

At the rear of the LTZ 400 is a linkage-type suspension with a adjustable, piggyback reservoir-style offering 9.1 in. of wheel travel and in. of ground clearance. Luckily the shock is highly adjustable our first impression is that the was so stiff the tires had a hard hooking up.

Our quick solution was to off almost all spring pressure and soften the compression screw to its limit, which helped but it’s still going to be stiff for a lot of riders. The best would be a softer rear which we may try next. After our suspension changes the LTZ really a completely different machine and one we began to like!

It had performance, handling, and looks!

put a lot of time into the fine on the ‘Z 400, and the caster, wheelbase, and width were all for performance. Even the tubular chassis was redesigned with tubing in some areas for reliability and to enhance the ride. The is a machine that is a blast to on all day with enough power for anybody, and handling that is predictable, and easy to control.


A huge factor we in any new model is maintenance. It should be and quick, or people will it. Thankfully on the LTZ 400 the air filter is easily under the seat, and the oil filter in located on the right side of the There is no excuse not to have oil and a clean air filter on this

Unfortunately chain adjustment is a pain on the LTZ 400, and adjustment is a of several wrenches and bolts a sliding axle carrier, than the super simple type system found on the LTR Yes it’s a pain, but we understand the on this one. Tooling up for a cast swingarm would a fortune, and we’ll give a pass this time and that in future models get our wish for a simpler chain system.

Perfect Playmate

We really the Suzuki LTZ 400 and it is easily our choice for the ATV in its class. It’s so good in we believe it is better than competing 450 models. Sure the adjustment can be a pain and the shocks are a stiff, but there is so much to about the LTZ 400 the benefits far outweigh any It’s very comfortable, to ride, handling is precise, and the EFI the motor a nice, peppy In our experience it has also proven reliable.

We’re always to take one to the tack or trails, and for riders it will be perfect!
