Honda Nsr125r K (1991)
1991 Honda Nsr125r K
CarHunch analysed 181 real MOT records for the 1991 Honda Nsr125r K. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1991 Honda NSR125R-K is in deep trouble on the MOT: just 3.5% of the 181 bikes tested passed first time, a staggering 76.5 percentage points below the UK average of 80%. The tiny dangerous defect rate of 0.5% is the only bright spot, but it barely matters given these bikes are almost universally failing their tests.
At 22,435 miles median mileage, these are genuinely low-mileage machines for their age, yet they're still falling apart—averaging 0.06 failures and 0.1 advisories per vehicle suggests systemic deterioration rather than wear-related issues. If you're considering one, assume a full strip-down inspection and budget heavily for restoration work; the MOT pass rate tells you these 33-year-old bikes need serious mechanical attention before they're safe or legal on the road.
What to check before buying a 1991 Honda Nsr125r K
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.
