2018 KTM Rc 125 18

CarHunch analysed 117 real MOT records for the 2018 KTM Rc 125 18. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2018 KTM RC 125 has a first-time pass rate of 67.3%, which trails the UK average of 80% by a meaningful margin—a sign that these bikes need more attention before MOT. Dangerous defects have affected 18.8% of the cohort, sitting just below the threshold of concern, so while not a major red flag, it's worth factoring into your pre-purchase inspection.

At just under 10,000 miles median mileage, these bikes are lightly used for their age, which makes the below-average pass rate more telling—it points to maintenance gaps rather than wear and tear. With an average of 2.6 advisories per vehicle, expect minor niggles like chain wear or brake pad thickness to crop up; get a pre-MOT check from a KTM-familiar mechanic before your test, as these small issues are often correctable and inexpensive to fix before they become failures.

What to check before buying a 2018 KTM Rc 125 18

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.
