GT300LC

300cc Liquid Cooled Development and Testing. GT300LC.


Granturismo have been developing a truly game changing engine for the Lambretta motor scooter since its first conception in 2015. The GT intercontinental engine cases that have been available since 2016 were designed to allow for the use of other larger barrels and larger crank shafts in regard to their casting. In standard format the cases have much more “meat” than needed, but when machined for use with the Rotax liquid cooled barrels and the Simonini air cooled barrel option which both also use the much larger purpose made GT crank it becomes apparent why the GT case is so “meaty”

This article refers to the Rotax liquid cooled variants which have a 76mm bore and 64mm stroke giving just over 290cc

More about the air cooled option at a later date when they have been ran and tested.
