Rear hub nut for Swing arm brace -POLINI Torsen WD- Minarelli 50 cc (62,6mm)

The Polini swingarm contributes to a significant reinforcement of the motor housing designed as a drive set swingarm. The housing doesn't twist anymore and the rear wheel is guided much more stable.
The swingarm fits Plug & Play only with some Polini exhaust systems.
The assembly is very easy and is made through the rear wheel nut and the exhaust bracket.
Originally designed for racing, it makes sense on the road and a slim foot.

Fits with the following Polini exhaust systems, all others have to be modified:

POLINI SCOOTER TEAM 2

BIG EVOLUTION 70 cc

BIG EVOLUTION 83/94 cc
