2007 Suzuki DR-Z 400SM Overview
For 2007, Suzuki offers the DR-Z 400SM as a super motard motorcycle with 398 cc on tap. The 2007 Suzuki DR-Z 400SM is built around a Single cylinder engine running DOHC valve actuation, a compression ratio of 11.3:1. Out on the road, the DR-Z 400SM delivers 29.2 kW @ 8500 rpm (rear wheel: 24.9 kW / 33.4 hp of peak power and 39 Nm @ 6600 rpm of torque. Flat out, it's quoted at 145 km/h. In everyday use, the 2007 DR-Z 400SM tips the scales at 146 kg, carries a 10-litre fuel tank, offers a seat height of 890 mm and spans a 1460 mm wheelbase. That's roughly 64.5 kg lighter than the average super motard motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2007 Suzuki DR-Z 400SM spec sheet below.
2007 DR-Z 400SM - Pros & Cons
Strengths
-
⚡
Strong power output: Peak output on the DR-Z 400SM is 29.2 kW @ 8500 rpm (rear wheel: 24.9 kW / 33.4 hp and 39 Nm @ 6600 rpm of torque - strong numbers for what it is.
Considerations
-
🔧
Carburetor fuelling: Carburetion is more hands-on than fuel injection - plan on periodic jetting and cleaning as part of routine ownership.
-
📏
Tall seat height: A 890 mm seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.
-
⛽
Modest fuel capacity: A 10-litre tank keeps things light but means budgeting for more frequent fuel stops on any longer ride.
-
⚙️
Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.
Wear Points & Servicing Notes
Cooling system servicing
With Liquid cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.
Carburetor maintenance
Being carbureted, the DR-Z 400SM is more sensitive to stale fuel and altitude changes than a fuel-injected bike - a carb clean and rejet restores crisp throttle response after any extended lay-up.
Valve clearance checks
Valve clearances on DOHC-equipped engines like the DR-Z 400SM's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.
Brake disc and pad wear
Single 310 mm floating disc, 2 piston caliper up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.
Suspension condition on used examples
Suspension duties are handled by Telescopic, 49 mm, oil-damped, 11-way compression damping, adjustable spring preload up front and Link-type, fully adjustable spring preload, 26-way compression damping at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.
Final drive maintenance
Chain final drive on the DR-Z 400SM means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.
Frame & chassis check
The Chrome-moly steel frame, single front down tube chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.
DR-Z 400SM - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2007 Suzuki DR-Z 400SM should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept DR-Z 400SM settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for a DR-Z 400SM's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.
Carburetor upkeep
A DR-Z 400SM that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.
Valve clearance service
There's no reliable seat-of-the-pants way to tell if a DR-Z 400SM's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
