The 2018 Lexmoto Viper SK 125-22A is significantly less reliable than the UK average, with a first-time MOT pass rate of just 47.3% against the national benchmark of 80%. One in five of these bikes (20.9%) have recorded a dangerous defect during their MOT history, which is a genuine safety concern for prospective buyers.

What to check before buying a 2018 Lexmoto Viper Sk 125 22a

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.
  • ⚠️ 20.9% 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.
