Name Polini Torque Spring Sport Piaggio Sfera / Zip Item No. U243.030 Brand Polini
Torque springs are quite important when it comes to adjusting your transmission. They put pressure on the rear pulley and influence clutch performance. They have to be replaced with a harder spring as soon as the belt is starting to slip and the engine is starting to underperform in spite of using lighter weights. If you're going for a harder spring, you'll have to readjust your variator.
