How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the SUPER GLIDE beats 4 of its 4 closest rivals (HARLEY-DAVIDSON FLSTF, HARLEY-DAVIDSON FLSTC, HARLEY-DAVIDSON XL1200C).

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 SUPER GLIDE.

Pass rate by registration year

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

Best year to buy used: 2014 (91.9% pass). Weakest: 2013 (87.3%).
