The Jasil transmission kit includes a front sprocket (15 teeth), rear sprocket (39 teeth), and a 52-link chain. The kit provides an 18% modified gear ratio compared to the standard specifications — useful if you want to adjust the top speed or acceleration of your moped or scooter.
Jasil manufactures this set in the EU, ensuring consistent dimensional tolerances and reliable quality. The set is suitable for engines with both horizontal and vertical Minarelli engine configurations.
Always replace the chain and sprockets at the same time: a new chain on worn sprockets (or vice versa) greatly accelerates wear and shortens the lifespan of the entire drivetrain.
