Should I check the MOT history before buying a 2015 Triumph Rocket?

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.

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.

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.

The 2015 Triumph Rocket is a strong performer with a 92.2% first-time MOT pass rate, significantly ahead of the UK average of 80%, suggesting these bikes have been well-maintained overall. However, 14.3% have recorded a dangerous defect at some point, which is a modest but genuine concern worth checking on during a pre-purchase inspection.

With a median mileage of just 8,400 miles for a nine-year-old machine, these are lightly used bikes, and that low mileage explains the healthy pass rates. The average of 0.54 failures and 1.8 advisories per test indicates minor wear items rather than serious mechanical problems—so before buying, have a mechanic specifically inspect brakes, lights, and suspension to catch the sorts of small issues that typically trip up these bikes.

We have limited data for the 2015 Triumph Rocket — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 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.
