Yamaha Rd350 (1984)
1984 Yamaha Rd350
CarHunch analysed 299 real MOT records for the 1984 Yamaha Rd350. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The RD350 is a genuinely reliable machine by modern MOT standards, with an 89.6% first-time pass rate that sits well above the UK average of 80%—and dangerous defects are rare at just 6%. This classic 350cc two-stroke is fundamentally sound when properly maintained, though you'll encounter the occasional failure or advisory during ownership.
These surviving examples average around 23,800 miles, which is reasonable mileage for a 40-year-old bike and suggests the best ones have been looked after. The typical bike picks up less than one failure per test and less than two advisories, pointing to wear rather than fundamental design problems—so focus your pre-purchase inspection on bodywork condition, fuel system cleanliness, and whether the seller can prove regular servicing history.
What to check before buying a 1984 Yamaha Rd350
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.
