How rivals compare
On first-time pass rate the TC1 beats 2 of its 4 closest rivals (BMW R1200, KAWASAKI ZX-6R, BMW R1150).
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 TC1.
Pass rate by registration year
Best year to buy used: 2020 (91.7% pass). Weakest: 2021 (69.0%).
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.
