Description

Hearing a rattling sound behind the variator cover while your engine is idling? That's usually a sign that your rollers are worn out. Worn weights can negatively impact your ride's acceleration, top speed, and overall performance. For smoother rides, it would be wise to replace them right away. But generic rollers simply won't do. You'll want replacement parts that are made tough and precisely engineered for your ride. Get your ride back on track with these Racing Driving Wheel Rollers from RUTU! Our variator rollers are crafted for durability. They're manufactured using an injection mold process, which means that both the shell and core are produced at the same time. The two parts connect seamlessly and and won't fall apart. Both are also made from wearproof materials, which means you'll get to enjoy using them for longer. To cater to the different power needs of different riders, we manufacture our sliders in different weights, from 4 grams to 8 grams. The pure metal core is zinc coated and rustproof. This means you don't have to worry about rust changing the weight of the rollers. Made in the same size and shape, you can easily swap these out and change weights without hassle. When it comes to quality aftermarket parts, look no further than those produced by RUTU. Made from quality materials and exceptional manufacturing processes, you can count on our spare parts to deliver in terms of longevity and performance.

Get your hands on a set of wear-resilient and high-performance pulley beads. They’re the perfect replacement rollers for two-wheeled rides with GY6 engines. They come in 8 different weights; you should have no trouble finding one to meet your specific power requirements. Here are more details about our variator rollers: Choose lighter rollers for improved acceleration and re-acceleration. Go for heavier rollers to increase top end speed. Choose from a wide range of weights. They come with the same size and shape so you can mix and match them depending on your needs. The galvanized all-metal roller core's rust-proof and has good centrifugal effect. To install, first remove the engine cover, followed by the belt and viarator. Remove the old rollers from the driving wheel and replace them with the new rollers. Install the drive wheel back into place. Then, attach the belt and return the engine side cover.
