Aprilia RS 50 (1999)
1999 Aprilia RS 50
CarHunch analysed 288 real MOT records for the 1999 Aprilia RS 50. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1999 Aprilia RS 50 has a first-time pass rate of 64.6%, well below the UK average of 80%, signalling reliability concerns for this nearly quarter-century-old machine. One in five of these bikes (20.8%) have recorded a dangerous defect at some point, which is a genuine buyer red flag.
At an average mileage of 22,726 miles, these are relatively low-mileage specimens for their age, yet they still average 1.88 failures and 5.1 advisories per test—suggesting age and storage issues matter more than riding hours on these older scooters. Before purchasing, insist on a pre-purchase inspection by a Vespa or small-scooter specialist, as the high advisory count hints at corroded fuel systems and seized components that casual sellers often overlook.
What to check before buying a 1999 Aprilia RS 50
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.
- ⚠️ 20.8% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
