How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the TS150 beats 0 of its 1 closest rivals (BSA BANTAM).

BSA BANTAM 88.7% pass · 7,201 tests

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 TS150.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 1981 (92.7% pass). Weakest: 1980 (85.2%).

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.
