The 2008 Triumph Street Triple passes its MOT on first attempt 80.9% of the time—fractionally above the UK average of 80%—so it's a reliably sound choice mechanically. Only 13% have ever recorded a dangerous defect, which is well within acceptable limits and shouldn't concern a prospective buyer.

At an average of 14,006 miles, these bikes are relatively lightly used for their age, which partly explains the solid pass rate. With 1.2 failures and 4.0 advisories per vehicle on average, expect minor wear items rather than structural problems—check the exhaust, suspension bushes and brake lines when viewing one, and factor in routine servicing costs.

The 2008 Triumph Street Triple passes its MOT first time more often than most UK vehicles (89.6% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ 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 89.6% 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 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 851 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.
