How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the T140E beats 4 of its 4 closest rivals (KAWASAKI ZX-6R, SUZUKI GSF600, YAMAHA FZS600).

KAWASAKI ZX-6R 78.1% pass · 174k tests SUZUKI GSF600 77.3% pass · 143k tests YAMAHA FZS600 82.6% pass · 137k tests TRIUMPH SPRINT 85.6% pass · 133k 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 T140E.

Pass rate by registration year

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

Best year to buy used: 1980 (88.6% pass). Weakest: 1981 (84.8%).

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.
