Suzuki DR-Z4SM Top Speed, Specs & Review (2026)
TL;DR
- The Suzuki DR-Z4SM top speed is roughly 88 to 90 mph, based on road tester reports. No GPS-verified run has been published.
- It makes a claimed 38 hp and 27.3 lb-ft from a 398cc fuel-injected single and weighs a claimed 340 lb wet.
- No independent 0-60 time exists yet, so any number you see online is an estimate.
- It’s a street supermoto with a 35.0 in seat, 17-inch wheels, traction control and a slipper clutch.
- It launched at $8,999. The real drawbacks are modest power, a 2.3 gal tank and a firm, tall seat.

How Fast Is the Suzuki DR-Z4SM?
The DR-Z4SM tops out at about 88 to 90 mph. RevZilla’s tester ran it flat out on the K1 Circuit straight and reported 88 mph (RevZilla, 2025). Rider Magazine’s tester wrote that it does over 90 mph, though he framed it as secondhand (Rider Magazine, 2025).
Suzuki hasn’t published an official top speed. As of November 2026, we found no GPS-timed run in the major magazine tests. Treat 88 to 90 mph as a field estimate, not a lab number.
The figure makes sense. You’ve got 38 claimed hp pushing an upright rider through the wind, with short gearing built for corner exits. This bike is happier snapping between corners than holding 80 mph on the interstate.
What Is the DR-Z4SM 0-60 Time?
No independent 0-60 time has been published for the DR-Z4SM as of November 2026. Suzuki doesn’t claim one, and the tests we checked report none. Sites that list a figure are using formulas or recycling numbers from the old DR-Z400SM.
What you can work with is the weight. At 340 lb wet and 38 claimed hp, the power-to-weight ratio is about 0.11 hp per pound. The new bike gained 16 lb over the old DR-Z400SM, but testers say you won’t feel it once moving.
Traction control and three drive modes let you tame the throttle on slick pavement. We’ll update this page when a timed run appears.
How Much Power Does the 398cc Single Really Make?
On paper, the DR-Z4SM makes 38 hp at 8,000 rpm and 27.3 lb-ft at 6,500 rpm. Rear-wheel numbers run lower. Cycle World put the DR-Z4S dual-sport, which shares this engine and claimed output, on its Dynojet 250i and measured 33.5 hp at 8,100 rpm and 23.9 lb-ft at 6,600 rpm (Cycle World, 2025).
That gap is normal. Claimed figures are measured at the crank, and the chain, gearbox and tire eat some power before it reaches the dyno roller. The supermoto itself hasn’t been dyno tested in the sources we checked, so treat the dual-sport result as a close proxy.
The 42 mm ride-by-wire throttle body and 10-hole injector replace the old carburetor. That means cleaner low-rpm fueling and no choke fiddling on a cold spring morning.
How Does the DR-Z4SM Handle and Stop?
The DR-Z4SM handles like a dirt bike with road tires. A twin-spar steel frame, aluminum subframe and aluminum swingarm hold up 17-inch wheels, and the long-travel suspension keeps the tires planted over rough pavement. Both ends are adjustable.
The 310 mm front disc and 2-piston Nissin caliper are enough for a 340 lb bike. ABS can be switched off, which supermoto riders want for backing it in.
Electronics are simple: ride-by-wire, three drive modes, Suzuki Traction Control, Easy Start and an LED headlight. There’s no quickshifter and no TFT display.
Geometry matters here too. The 26.5 degree rake and 3.74 in trail keep steering quick, and the 57.7 in wheelbase makes the bike easy to flick through tight turns. Keep tire pressure checks on your pre-ride list, since sticky street rubber is what makes a supermoto fun.
Who Should Buy the DR-Z4SM and What Are the Drawbacks?
The DR-Z4SM suits riders who want a light, playful street bike and don’t care about freeway speed. It works for short commutes, back roads and track days.
Here are the honest drawbacks.
- Price: $8,999 at launch is a lot for 38 hp.
- Seat height: 35.0 in is tall, and testers called the seat firm.
- Range: the 2.3 gal tank means frequent fuel stops.
- Highway manners: a 5-speed box and modest power make long slabs tiring.
If you want one bike for touring, look elsewhere. If you want a light bike that makes every corner fun, the DR-Z4SM delivers.
