Ducati St4s (2001)
2001 Ducati St4s
CarHunch analysed 163 real MOT records for the 2001 Ducati St4s. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2001 Ducati ST4S lands right at the UK average with a 79.1% first-time pass rate, suggesting typical reliability for a bike of this age—though the 11% of machines that have suffered dangerous defects is worth noting if you're buying used. These Italian sports-tourers have accumulated modest mileage (median 18,174 miles), which is encouraging for their age and suggests many have been cherished rather than thrashed.
Expect around 1.4 failures and 4 advisories per test cycle, meaning minor wear items and maintenance niggles are routine rather than serious structural problems. Before committing to one, run an independent inspection focusing on the desmo valve system and fuel system components, as these appear in the advisory pattern—a pre-purchase service history check is equally important given the bike's complexity.
What to check before buying a 2001 Ducati St4s
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
