Their precise weight allows for tuning to the nearest tenth of a gram to adjust acceleration, responsiveness, and shift regime. Compatible with several VESPA GRANTURISMO models (2006–2008, 200 cm3) — check compatibility with your variator before installation.
Installation advice: check the condition of the variator, belt, and original rollers before replacement. Replace the complete set to ensure smooth operation and even wear.
