How rivals compare
On first-time pass rate the GT185 beats 1 of its 2 closest rivals (BSA BANTAM, HONDA CB TWO FIFTY).
Rivals share this bike's type and sit within ±30% of its engine capacity, ≥ 5,000 tests. Card colour = better/worse first-time pass rate than the GT185.
Pass rate by registration year
Best year to buy used: 1978 (85.2% pass). Weakest: 1975 (80.6%).
First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.
