With my last 3 scooters I've replaced the stock rollers with Dr.Pulley sliders. I usually go 1 gram lighter and have been happy with the results. I am going to do this on my '23 People S 150i ABS. Does anyone know for sure what weight rollers this scooter comes with from the factory. I can tear it down, weigh the rollers, and order the correct sliders. The problem with that is the several days or weeks of down time waiting for parts. My last scooter (X-Town 300i ABS), I got some bad info and ended up installing sliders that were the same weight (16g) as the stock rollers. If no one knows for sure, I'll tear it down and hope for several rainy days until my new parts come in.
