NEW polini evolution variated gearbox for vespa piaggio mopeds like ciao, SI, bravo, grande, boss, grillo and more! completely brand new casting!
from POLINI:
"All the technical innovations of the Polini Evolution Gear Crankcase
have been designed to increase resistance in the most toughest uses and
ensure strength in case of racing uses.
The new crankcase is characterized by a modern and integrated design with various technical characteristics:
- Increase of the sections of bearing housings to improve stiffness.
- The wheel axle bearing has been reworked with larger diameter.
- Pressed roller bearings and oil seals with spring-loaded radial lip.
- 5 hexagonal head screws compared to the 4 hexagonal head screws present in the original reducer.
- The gasket that seals the two crankcases is made of a layer of
aluminum to increase stiffness and two rubber surface layers for sealing
which guarantee its duration over time.
The Polini Evolution gear cover for Piaggio mopeds
can be mounted both with the original gears and with Polini gears (item
202.1425 and 202.1427 or 202.1426) combined with the shims code 246.058
(Attention: after mounting the Polini gear crankcase, the “bike” mode
cannot be used).
note this is just the gearbox! it DOES come with hardware, oil seals, gear shims and bearings! no gear set is included tho. grab some here and enjoy variating!!
take note ... NO bicycle mode with this gearbox.
includes instructions which you must read cause for once they actually have critical info in them. if you don't read them you may set it up wrong.. so grab a cup of tea and enjoy reading them.
