Should I check the MOT history before buying a 2008 Skyjet Sj 125 23?

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 2008 Skyjet Sj 125 23?

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 2008 Skyjet Sj 125 23?

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 2008 Skyjet Sj 125 23 reliable?

Based on MOT data from 344 vehicles, the 2008 Skyjet Sj 125 23 has a first-time MOT pass rate of 65.7%, indicating average reliability for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2008 Skyjet Sj 125 23?

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.

Moderate sample. 344 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This 2008 SKYJET SJ 125-23 is a genuinely troublesome proposition: only 31% pass their MOT first time against the UK average of 80%, meaning you're looking at a vehicle that typically needs multiple visits to the test centre. Nearly 11% of these machines have recorded dangerous defects, which is a serious safety concern for any prospective buyer.

The median mileage of 5,440 miles suggests these are lightly-used bikes, yet they're still averaging 0.68 failures and 2.0 advisories per MOT—that's a high fault count relative to usage, pointing to design or build quality issues rather than just age-related wear. Before buying one, get a pre-purchase inspection from a specialist technician, because the MOT history alone indicates chronic reliability problems that routine maintenance won't fix.

The 2008 Skyjet Sj 125 23 has a below-average first-time pass rate (65.7% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 2 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 344 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
