Should I check the MOT history before buying a 2004 Triumph Rocket 111?

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 2004 Triumph Rocket 111?

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 2004 Triumph Rocket 111?

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 2004 Triumph Rocket 111 reliable?

Based on MOT data from 221 vehicles, the 2004 Triumph Rocket 111 has a first-time MOT pass rate of 90.6%, 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 2004 Triumph Rocket 111?

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.

The 2004 Triumph Rocket 111 has a first-time pass rate of 77.5%, which trails the UK average of 80% by a modest margin—not a red flag, but worth noting as a slightly higher-than-average failure risk. With 15.8% of vehicles ever recording a dangerous defect, this bike sits in an acceptable range and shouldn't deter buyers on safety grounds alone.

These bikes are running relatively low mileage for their age, with a median of just 13,944 miles, suggesting many are weekend or collector machines rather than daily commuters. The average of 1.24 failures and 4.4 advisories per test indicates routine wear items (likely exhaust, cables, and brake components) are the main maintenance concern—budget for regular attention to consumables and inspect any example closely for rust and corrosion before you buy.
