Suzuki DRZ400S: An Everyman Dirt Bike, for Decades
If there were any logic in the world, if you looked up the word reliable in a dictionary, there would simply be a picture of a Suzuki DRZ400. Since the turn of the century, the big Suzuki has been used and abused all over the world, from California to Canberra and Canterbury to Cape Town, and put up with anything thrown at it. Like a motorcycling version of The Terminator, there seemed to be nothing that could stop the mighty DRZ – except perhaps the Euro 3 regulations.

While the technocrats in Brussels might have temporarily defeated the Suzuki in the UK a mere nine years after its launch, for the rest of the planet the DRZ has stayed the consummate trail bike for over 25 years and is still going strong, despite being superseded by the new fuel-injected and slightly sanitised DR-Z4S. Powerful enough to slog through everything from a Welsh bog to the Australian outback, and comfortable enough to make hours of tarmac perfectly bearable thanks to that almost sofa-like seat, the DRZ400 remains a firm favourite with dirt riders – even the ones who sold theirs long ago and moved on to lighter, more agile machines. The mere mention of those three letters, DRZ, can still set an older trail rider going a bit misty-eyed.
No wonder it is one of the three bikes Ride Expeditions offers for our Mongolian tour, the Warrior’s Trail. The DRZ is still an extremely capable trail bike and ideal for crossing those massive landscapes in a degree more comfort than the more stripped-back enduro machines. So what makes the DRZ such a likeable old rogue?
Water-cooled Weapon
Powering the DRZ is an ultra-reliable and versatile 398 cc single-cylinder DOHC motor. Unlike its elder brother, the awesome DR650 that is a stalwart of the round-the-world community, the DRZ is water-cooled, with twin radiators sitting high up alongside the 10-litre tank. Power is on the soft side of punchy as stock, somewhere between 35 and 39 bhp depending on the age and health of the motor, though many owners reach for aftermarket exhausts and re-jet kits to free up a few more ponies. Even stock, it has a healthy punch and enough torque to pull just over 90 mph if called on – arguably a tad much for full knobblies.
Below the barrel, the Zook has a conventional, fairly bombproof cable-operated wet clutch and a five-speed gearbox. Of everything about the bike, it is that gearbox that draws the most comment on forums and owners’ groups, with people forever wishing Suzuki would add a sixth gear. Even on the 2026 DR-Z4S, Suzuki has kept to the same script, still leaving alone arguably the only bit that needed changing on the outgoing 400.
Big Frame
One of the things that makes the DRZ so tough and so easy to repair out on an adventure is the steel perimeter frame. Capable of taking big riders and big loads, it is as tough as a boiled owl and shrugs off anything you throw at it. On the odd occasion you do break a bit, a man with a welder will have you going again in no time – try that on an aluminium-framed race bike. At the rear sits a substantial aluminium subframe with the strength for all the luggage you might want on a big trip, although on a Ride Expeditions tour your luggage rides in the support truck, so that is one less thing to think about.
Soft and Squidgy
The suspension is a big part of why the DRZ is such a crowd-pleaser for long days on the trail, and ideal for Mongolia. It is famously soft and plush, letting you float over the bumps in a thoroughly agreeable way. The faster you go, the more you find the limits of that softness – this is a trail bike, not a full enduro, so if you want to ride at Dakar pace you will want stiffer springs and some work on the damping. But for the rest of us mortals, the stock kit does the job: chunky USD forks up front, adjustable for preload, and a centrally mounted, linkage-operated shock at the back, again adjustable for preload, on a long, sleek aluminium swingarm.
Stop It Now
Braking is the familiar off-road pattern. On the 21-inch front wheel there is a 250 mm disc with a twin-pot Nissin caliper, and at the rear a 220 mm disc with a single-pot caliper. Feel is good thanks to the long front lever and the rear pedal, with a progressive bite that suits everything from delicate trail braking to a hard stop. They are no Brembo Stylemas, but if you are expecting sportsbike brakes on an off-road bike designed 26 years ago, you need a rethink.
Everything Else
The steel bars are a sensible width with a nice bend as stock, though on an older bike the odds they are still the originals are slim. The cockpit is minimal next to a road bike: a small rectangular LCD behind the headlight cowl, with more trip functions than you need unless you are running a roadbook, plus a clock and a speedo. Alongside sits a block of idiot lights for indicators, neutral, high beam and low oil. That is about it, and to be honest there is not much more on the 2026 DR-Z4S. The seat is deep and comfortable at a tallish 935 mm that sinks a fair bit on the soft suspension, and while the bike is reasonably narrow through the middle when you stand, it is nothing like as waiflike as a KTM or GasGas.
Trail Time
As Suzuki’s best-selling trail bike, you would hope the DRZ performs out on the trail, and it does. That soft yet punchy power, the quiet, almost apologetic exhaust note and the forgiving suspension make it a true all-day bike you can ride from sunrise to sunset – pretty much what we do in Mongolia. From blasting across the wide-open expanses to picking through the technical trails in the cool larch forests up north, it is in its element. The geometry is forgiving enough not to punish mistakes if you are less experienced, yet sharp enough to make a seasoned rider grin like the proverbial Cheshire cat.
If you want to go very fast, you will find the limits of the stock suspension, but for most riding – just like the Warrior’s Trail – the Suzuki simply floats across the landscape. The seat is soft enough to stay sat down, though getting up on the pegs improves the handling and the whole experience when it gets rough. Against a more modern trail or enduro bike you do notice the weight: close to 30 kilos heavier than the bright young things, the DRZ lacks the agility to skip across ruts or loft the front on a fistful of throttle. Horses for courses. If you want the latest riding experience, it will not come from a DRZ – and that is rather the point.

Decisions, Decisions
So if you are heading to Mongolia, which bike do you choose? The easy modern manners of the GasGas EC 350F, the barnstorming power and agility of the excellent KTM EXC 450, or the relaxed, thoroughly enjoyable trail riding only the DRZ delivers? There are merits to all three, and it really comes down to the rider you are and how much off-road you have under your belt. For the committed dirt junkie it is the orange bike every time; for the occasional off-road rider, probably the red of the GasGas. But if you are coming to Mongolia straight off a road bike and just want something easy to ride all day, the Suzuki is the one. No wonder it has lasted more than a quarter of a century. As the Aussies would say, she’s a beaut.

Who the KTM 450 EXC Is Best Suited To
So is the KTM EXC 450 the right bike for you on a Ride Expeditions tour?
Well, that depends on your experience and background. If you are a committed off-road rider back home, have a similar enduro bike in the garage, and are taller than around 5’11”, then the 450 is a superb choice. It is powerful, beautifully agile and a complete joy to ride.
If you are less experienced off-road, or simply prefer a slightly less powerful bike that can be lowered, the GasGas EC350F might be a better option. And if you prefer the feel of a big, comfortable single, then the Suzuki DRZ400 may be the one for you.
Frequently Asked Questions
Why did Ride Expeditions choose the KTM 450 EXC for the Trail & Enduro tours in Mongolia?
Because it suits the terrain so well.
Mongolia throws everything at a bike: long, fast open trails, rougher technical sections, rocky climbs and big days in the saddle. The KTM 450 EXC has the power, balance and suspension to handle all of that, but it is also far more manageable than older big-capacity enduro bikes used to be. That makes it a great fit for riders who want a serious off-road machine that can still stay composed when the trail gets slower or more demanding.
Is the KTM 450 EXC too aggressive for non-racers?
Not in the way older open-class enduro bikes used to be.
The 450 is still a fast and capable machine, but it delivers its performance in a far more usable way than many riders expect. In tighter, more technical terrain, it feels smooth, controllable and well balanced, rather than nervous or hard work.
It still suits riders with solid off-road experience best, but it is not the wild, exhausting brute that some older 450s could be.
What is the seat height on the KTM 450 EXC, and who is it best for?
The seat height is 963 mm, so it is definitely on the tall side.
For that reason, the KTM 450 EXC tends to suit taller riders best, roughly 5’11” and up, unless you are already very comfortable on tall off-road bikes. If you are confident in technical terrain and used to enduro-style machines, the height is less of an issue. If not, it is something worth thinking about before choosing the 450 over a lower or more forgiving option.
Can the KTM 450 EXC be lowered easily?
Not as easily as bikes with linkage rear suspension.
The EXC uses KTM’s linkless PDS setup, which keeps things simple and works brilliantly off road, but it also means lowering is not usually a quick or straightforward job. It can be done, but it generally takes more thought than it would on some other bikes. If seat height is a concern, it is worth considering that before committing to the 450.
