Our Verdict
A highly recommended purchase for a collector or enthusiast. This 1998 Triumph Adventurer is a rare find with an exceptionally clean history and remarkably low mileage.
Given the extremely low mileage for a 1998 model, your primary focus should be on 'age-related' degradation rather than wear and tear. Check for perished rubber hoses, tyre date codes (even if they have tread, tyres over five years old should be replaced), and ensure the fuel system has been maintained to prevent gumming from infrequent use.
Request a full service history to see if the oil has been changed regularly despite the low mileage. Negotiate based on any immediate maintenance required to bring the bike up to a 'road-ready' standard if it has been sitting idle between its low-mileage trips.
As a classic 885cc petrol motorcycle, fuel economy will be modest compared to modern bikes, but typical for its era. Insurance for a classic Triumph is generally affordable, often falling into a mid-range group, and road tax is minimal for a vehicle of this age.
Maintenance costs should remain low provided the bike continues to be treated as a collector's item. Annual costs will primarily consist of the MOT, basic servicing, and insurance, with an estimated total spend reflecting its low-usage profile.
Inspect the braking system thoroughly; while the 2015 MOT noted front brake pads nearing their limit, ensure all fluid has been flushed recently to avoid moisture contamination. Check the black paintwork for any signs of fading or oxidation that can occur with age, even in low-mileage vehicles.
Pay close attention to the battery health and electrical connections, as bikes with such low annual mileage (averaging roughly 700-1,000 miles per year recently) are prone to battery drain. Verify that the engine starts cleanly and idles smoothly without hesitation.
This black 885cc Triumph Adventurer is in an enviable state of preservation, showing just 18,031 miles on the odometer as of July 2025. The MOT history is exemplary, boasting a consistent string of passes from 2011 through 2025 with almost no advisories. It represents a well-maintained example of a classic British tourer.
While specific aggregate data is unavailable, this individual vehicle's 15-year MOT streak suggests high reliability and diligent ownership.
