Stage6 gear-up kit for Speedfight/ Trekker/ Vivacity mopeds.

Taller gears in the transmission reduce the overall reduction factor of the gearbox.
Provided the engine is powerful enough to pull the taller gears, this modification will also raise top speed.

Only use with tuning kits (e.g. 70cc sports cylinder upwards) as original standard cylinders are not normally powerful enough to pull this sort of gearing.

The 'Race' kit is will offer higher gearing and higher top speed but you will need a very highly tuned scooter to make use of it (e.g. Stage6 Racing 70cc)!

Contrary to common gear units, the ones from Stage6 come ready pressed for easy DIY home fitting and are available at an unbeatable price, simply replace the old gear unit with the new one - and that's it!
