How rivals compare
On first-time pass rate the JET 100 beats 0 of its 4 closest rivals (PIAGGIO VESPA, HONDA PCX 125, HONDA Vision 110).
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 JET 100.
Pass rate by registration year
Best year to buy used: 2000 (71.2% pass). Weakest: 2001 (69.8%).
