How rivals compare

same type, similar capacity, high test volume

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

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 STREET.

Pass rate by registration year
