2021 Wk Bikes Scrambler 125

CarHunch analysed 156 real MOT records for the 2021 Wk Bikes Scrambler 125. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2021 WK Bikes Scrambler 125 has a first-time MOT pass rate of 54.1%, significantly below the UK average of 80%, suggesting reliability issues are common in this cohort. With 8.3% of vehicles having ever recorded a dangerous defect, safety concerns exist but aren't widespread enough to be a deal-breaker for most buyers.

At an average mileage of 3,888 miles for vehicles now around three years old, these bikes are lightly used, yet they're still failing MOTs at nearly twice the expected rate—pointing to design or manufacturing issues rather than wear and tear. Before committing to purchase, request the full MOT history and specifically check whether the failures cluster around the same components; this will tell you if it's a known weak spot you can budget for or a scattered pattern suggesting poor build quality.

What to check before buying a 2021 Wk Bikes Scrambler 125

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.
