Gilera Unknown (2004)
2004 Gilera Unknown
CarHunch analysed 112 real MOT records for the 2004 Gilera Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2004 Gilera has a catastrophic 2.5% first-time pass rate against the UK average of 80%—petrol models don't pass at all—making it fundamentally unreliable for MOT compliance. Nearly 1% of these vehicles have recorded dangerous defects, a serious safety concern for any prospective buyer.
With only 112 vehicles analysed and an average mileage of just 3,821 miles, this cohort likely represents mostly stored or barely-used machines rather than regular runners, which explains the dismal pass rate; these bikes have been left dormant and are failing basic safety checks when finally tested. Before buying any 2004 Gilera, have a pre-purchase inspection by a qualified mechanic focus on fuel system, electrics, and brake condition, since the data suggests even low-mileage examples are problem-prone.
What to check before buying a 2004 Gilera Unknown
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.
