Pass rate by mileage

how the LIS's first-time pass rate falls with the odometer · class average 73.4%

A low-mileage LIS passes first time 85.0% of the time; by 20k that's 81.0%.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the LIS beats 3 of its 4 closest rivals (PIAGGIO VESPA, HONDA PCX 125, HONDA Vision 110).

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 LIS.

Pass rate by registration year

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

Best year to buy used: 1965 (88.3% pass). Weakest: 1967 (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.
