How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the CMX beats 4 of its 4 closest rivals (KAWASAKI ER5, YAMAHA XV535, SUZUKI GS500).

KAWASAKI ER5 77.4% pass · 53.1k tests YAMAHA XV535 82.7% pass · 48.1k tests SUZUKI GS500 76.4% pass · 44.9k tests SUZUKI AN400 86.2% pass · 27.1k 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 CMX.

Pass rate by registration year

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

Best year to buy used: 1986 (82.7% pass). Weakest: 1986 (82.7%).

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.
