Specially made for some Piaggio, Gilera and Italjet models these primary gear-up kits are easier to install than final-gearing alterations and using straight-cut gears means that it is possible to increase the load capacity of the transmission without losing the reliability of the original bearing and casing configuration. A helical gear-up kit (£59.98 SRP) is available for use with most 172cc upgrades, straight-cut version is the same price. For motors putting out more than 30hp there is the straight-cut kit at 71.98 SRP.
