YSS ‘Pro-X’ 300mm Performance Rear Shock for Piaggio Zip 50 – 100cc / Early Typhoon / Vespa LX50 / ET2 / ET4 / S 50
The Pro-X offers the entry into the world of YSS shock absorbers. The Double Action System allows the spring preload to be adjusted stepwise from the outside. The progressive damping and solid dimensioning of the piston rod ensure a safe driving experience and good road holding in all conditions.
The YSS ‘Pro-X’ shock is maybe the best value for money shock we sell. Not only does it offer significantly better performance than the stock shock, but also adjustability via 5 different levels of spring preload which can be easily changed via the supplied tool. The durable black finish wont attract too much attention, and will keep it looking great.
