straight teeth with sprocket guard kit

for 6-spring clutches

Malossi HTQ gears for Vespa PX pick up the legacy of the first gear design produced by Malossi in the late 1980s and early 1990s.
Completely redesigned, this pair of primary gears uses a straight-tooth configuration instead of the stock helical ones.
Malossi has worked hard to ensure the exceptional quietness of the gears, achieved by special machining of the teeth and associated contact surfaces, which are finished with obsessive care and verified at the evolution meter.
Malossi HTQ gears are made using only materials that pass the very strict standards imposed by our technicians through rigorous testing and trials.
The final processing uses numerically controlled machines, after which the Malossi HTQ gears undergo a complete thermochemical carburizing treatment at 900°C that gives them the hardness and
strength required.
The size and quality of the finished gears is finally verified on Zeiss three-dimensional inspection machines.
Paired two by two to respect the correct running clearance, Malossi HTQ gears are the most precious gift a true romantic enthusiast can give to his or her Vespa.
