Give your 2016-2020 Yamaha Zuma 125 the taller gearing it deserves with this premium 13/42 Final Drive Gear Set.
The factory 11/44 (4.00:1) setup is great for off-the-line punch but leaves you revving high on the freeway. This 3.23:1 ratio upgrade lengthens the overall gearing, lowering engine RPM by ~20% at cruising speeds while unlocking significantly higher top-end velocity — especially when paired with a big-bore kit, performance exhaust, or CVT upgrades.
Fitment
- 2016–2020 Yamaha Zuma 125 (all variants)
