Suzuki has finally revived one of its most iconic motorcycle platforms with the introduction of the all-new DR-Z4S and DR-Z4SM. Although both motorcycles share the same engine, chassis and electronics package, they were developed with very different riding environments in mind.

The DR-Z4S is Suzuki’s dual-sport offering, designed to tackle everything from city streets to gravel roads and off-road trails. Meanwhile, the DR-Z4SM takes the same platform and transforms it into a road-focused supermoto, prioritising agility, cornering performance and pure riding fun.

With both motorcycles looking almost identical at first glance, choosing between them can be surprisingly difficult. So, which one is the better choice for your riding style? Let’s compare them side by side.

Engine & Performance

Powering both the DR-Z4S and DR-Z4SM is the same 398cc liquid-cooled DOHC single-cylinder engine, producing 38 hp and 37 Nm of torque. Power is sent to the rear wheel through a five-speed manual gearbox paired with Suzuki’s SCAS assist and slipper clutch.

Since both motorcycles share the exact same powertrain, outright performance is nearly identical. The engine delivers strong low and mid-range torque, making acceleration feel lively without becoming intimidating. Whether you’re commuting through traffic or enjoying a spirited ride on the weekend, both motorcycles offer smooth throttle response and predictable power delivery.

Features & Technology

One area where neither motorcycle has an advantage is technology. Suzuki equips both the DR-Z4S and DR-Z4SM with exactly the same electronics package, meaning whichever model you choose, you’ll receive the same modern features.

Both motorcycles come equipped with a full LCD instrument display, Ride-by-Wire throttle, Suzuki Drive Mode Selector (SDMS), traction control, switchable ABS, and full LED lighting. These features bring the DR-Z platform up to modern standards while still maintaining its simple, rider-focused character.

The biggest difference lies in their hardware rather than their technology. The DR-Z4S features a 21-inch front wheel and 18-inch rear wheel wrapped in dual-purpose tyres, giving it the ability to tackle loose surfaces with confidence. The DR-Z4SM, on the other hand, uses 17-inch wheels fitted with road-biased tyres, making it noticeably sharper when carving through corners on tarmac.

Ergonomics & Riding Comfort

Suzuki DR-Z4S

Riding high with an impressive 920 mm seat height and upright ergonomics, the DR-Z4S gives you a commanding view of the road ahead. Its long-travel suspension effortlessly soak up potholes, speed bumps, and broken pavement, making it a comfortable partner for everything from extended rides to off-road detours. If you regularly tackle rough streets or love venturing off the beaten path, its plush, forgiving setup is a huge plus.

Suzuki DR-Z4SM

The DR-Z4SM on the other hand feels more compact and connected to the road. Its lower seat height of around 890 mm and smaller wheels inspire confidence during city riding, while the supermoto riding position encourages riders to attack corners with enthusiasm. It feels more agile when filtering through traffic and changing direction quickly, making it particularly enjoyable on winding roads and urban streets.

In terms of overall comfort, neither motorcycle is objectively better. Instead, it depends entirely on where you spend most of your time riding. The DR-Z4S favours versatility and comfort across mixed terrain, while the DR-Z4SM prioritises responsiveness and road-focused fun.

Who Is Each Bike For?

The Suzuki DR-Z4S is the ideal choice for riders who enjoy exploring beyond paved roads. If your weekend rides often include gravel trails, uneven backroads or light off-road adventures, the DR-Z4S offers the versatility and suspension travel needed to tackle a wide variety of terrain. It’s also a great option for riders who prioritise comfort and practicality over outright cornering performance.

The Suzuki DR-Z4SM, meanwhile, is aimed at riders who spend almost all of their time on the road. Its sharper steering, lower stance and road-focused tyres make it a far more entertaining motorcycle on twisty roads and in urban environments. If your idea of a perfect ride involves carving corners and enjoying a lightweight, playful motorcycle, the DR-Z4SM is likely the better fit.

Verdict

Sharing identical bones and electronic packages, these two sibling bikes cater to entirely different riding styles. The DR-Z4S is the ultimate all-rounder, equipped with long travel and dual-purpose rubber so you can point the front wheel down any dirt path without second-guessing.

Meanwhile, the DR-Z4SM is a pure street weapon, its lower center of gravity and supermoto setup bring serious fun to paved roads and city traffic. The right pick simply boils down to where you spend your time. If dirt detours call your name, go with the DR-Z4S. If nimble street handling and tarmac fun are what keep you hooked, the DR-Z4SM is guaranteed to put a bigger grin on your face.
