Ruckus & GY650 Dr. Pulley Sliders

Looking for a cheap and effective performance upgrade? Variator sliders are one of the easiest ways to improve takeoff acceleration and help your scooter hold RPMs while climbing hills 🏁💨 — and they make a noticeable difference without breaking the bank.

• ⚡ Faster acceleration vs stock rollers
• ⛰ Better hill climbing and power retention
• 🔧 Easy install upgrade for most 49cc scooters

The Details ⚙️

Most stock scooters come with 7.5–8 gram rollers, which are okay, but not ideal for responsiveness. Swapping them out for lighter sliders helps the engine stay in its powerband longer, giving you stronger acceleration, better part-throttle feel, and improved hill climbing.

For most riders, the starting recommendations are:

• 🧍 Under 200 lbs → 5g sliders
• 🧍‍♂️ Over 200 lbs → 4.5g sliders

If you've upgraded your clutch, springs, or variator, you may need to experiment with different weights to find the sweet spot.

Not sure which weight to choose? Try our tuning kit first 👍

Lighter sliders = more acceleration. Heavier sliders = more top speed. It’s all about balance.

Important Things to Note 🚨
