How rivals compare
On first-time pass rate the R100/7 beats 2 of its 4 closest rivals (BMW R1200, BMW R1150, TRIUMPH SPRINT).
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 R100/7.
Pass rate by registration year
Best year to buy used: 1979 (90.5% pass). Weakest: 1977 (86.9%).
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.
