How rivals compare
On first-time pass rate the EXC400 beats 0 of its 4 closest rivals (KAWASAKI ER5, SUZUKI GS500, SUZUKI AN400).
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 EXC400.
Pass rate by registration year
Best year to buy used: 2004 (80.0% pass). Weakest: 2002 (72.6%).
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.
