Should I check the MOT history before buying a 2005 Triumph Bonneville?

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 Triumph Bonneville?

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 Triumph Bonneville?

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 2005 Triumph Bonneville passes its MOT first time in 87.5% of cases, comfortably above the UK average of 80%, and dangerous defects are relatively uncommon at 15.2% of vehicles. This suggests a fundamentally reliable machine, though one in six will have picked up a serious safety issue by test time.

These bikes are running low mileage for their age—averaging just 11,731 miles—which partly explains the strong pass rate and means you're likely buying a garage queen rather than a hard-ridden commuter. The 4.8 advisories per vehicle point to minor wear items (cables, rubber, fluids) rather than structural problems, so budget for routine maintenance but expect the core engine and frame to be sound—get a pre-purchase inspection focused on fuel system and electrics, where older Triumphs commonly stumble.

The 2005 Triumph Bonneville passes its MOT first time at roughly the UK average rate (89.3%) — solid but worth checking this vehicle's history carefully.

⚠️ 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.

For context

✅ Good baseline reliability. A 89.3% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 4.8 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 748 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.

What tends to go wrong

Across 748 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Exhaust & emissions 55.7%

Exhaust noisy

Tyre wear 50.8%

Front Tyre worn close to the legal limit · Rear Tyre worn close to the legal limit · Rear Tyre tread depth is below minimum requirements of 1.0mm

Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.

Brake wear 30.8%

Front Roller brake test indicates slight fluctuation of brake effort · Rear Brake pad(s) close to minimum limit · Front Brake pad(s) close to minimum limit · …

Ask the seller when brakes were last serviced. If they don't know, factor in the cost.

Lighting 25.8%

Drive chain slightly loose · Headlamp aim too high · Wheel alignment slightly misaligned.

Usually cheap to fix. Worth confirming all lights work before collecting.

high mileage

Half of all 2005 Triumph Bonneville vehicles fall between 5,415 and 15,605 miles.

Is the mileage you're seeing normal?

✓ Under 5,415 miles — lower than most. Could be great, or could be a vehicle that rarely moved. Check test frequency and mileage progression in the MOT history.

✓ 5,415–15,605 miles — normal for age. This is where most 2005 Triumph Bonnevilles sit.

⚠ Over 21,066 miles — higher than typical. Not necessarily a problem, but check service history and look out for advisory build-up on tyres and brakes.

2005 Triumph Bonneville — Still on the Road

Most 2005 Triumph Bonnevilles are still being driven.

375 vehicles still getting MOTs in 2025 — 73% of the peak remain.

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2014–2025.
* The 2020 dip reflects the government's COVID-19 MOT exemption, which allowed certificates to be extended by six months — fewer tests were conducted that year.
