Should I check the MOT history before buying a 2005 Honda Cg 125 4?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2005 Honda Cg 125 4?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2005 Honda Cg 125 4?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Is the 2005 Honda Cg 125 4 reliable?

Based on MOT data from 266 vehicles, the 2005 Honda Cg 125 4 has a first-time MOT pass rate of 82.6%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2005 Honda Cg 125 4?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

This 2005 Honda CG 125 struggles badly on first-time MOT pass, achieving only 44.1% versus the UK average of 80%—a clear warning sign that these bikes are problem-prone as they age. The good news is that dangerous defects are relatively rare at 9%, so safety failures aren't the main concern; instead, you're looking at wear-and-tear issues that rack up across multiple systems.

At a median mileage of just 12,349 miles, these aren't heavily used machines, yet they still average 0.79 failures and 2.2 advisories per test, suggesting age and neglect matter more than hard riding. Before buying, budget for at least a full pre-purchase inspection and plan for routine maintenance on electrics, exhaust, and brake components—don't assume low mileage means low risk on a nearly 20-year-old bike.

We have limited data for the 2005 Honda Cg 125 4 — treat the figures below as indicative rather than definitive.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
