2008 Suzuki DRZ 400 SM K7 0.4L Petrol · WN08 OUO

The DR-Z400SM is known for being relatively frugal for a single-cylinder 400cc machine, with fuel economy typically in the range of 45-55 mpg depending on riding style, giving a real-world range of around 130-150 miles from its 10-litre tank. Road tax for this bike is minimal as it predates the recent VED changes affecting newer motorcycles, and insurance should sit in the lower groupings for this class of machine, particularly for riders with experience and a CBT or full licence.

Routine maintenance is straightforward and parts are reasonably priced compared with larger multi-cylinder sports bikes. Typical annual servicing — oil change, filter, chain adjustment, and brake checks — should fall in the £150-£250 region if carried out at home or by a small independent. Tyres, brake pads, and sprocket sets are the main wear items, and with low mileage these will likely be needed based on age rather than use. A realistic annual running cost including fuel, tax, insurance, and maintenance is around £800-£1,100.

Although the three recorded MOT tests were all clean, the age of the bike means several age-related items deserve close attention regardless of what the MOT certificate shows. Check the tyre sidewalls for the DOT date code; tyres older than five years will be perished even if they have plenty of tread, and given the 16-year age of this machine, replacement is almost certainly overdue. Inspect the chain and sprockets for wear and rust — a seized chain link or worn sprocket teeth can be expensive to put right. Also examine the fork stanchions for pitting or corrosion, as the inverted forks on the DR-Z400SM can suffer from seal leaks with age.

Lift the bike onto its centre stand and check for smooth steering movement and any clunks from the headstock bearings, which can wear on older examples. Look at the brake discs for corrosion around the edges and check the brake fluid colour — if it is dark, it should be flushed regardless of when it was last changed. Finally, inspect the cooling system hoses and radiator for any signs of perishing or leaks, and confirm the carburettor (or EFI components on later models) shows no signs of stale fuel deposits. The MOT history cannot reveal any of these age-related concerns, so a hands-on inspection is essential.
