Dr. Pulley
More than 30 years ago, we were a small company that focused on high-end composite materials. Armed with the expertise on material and mechanical design, we then entered the two-wheel industry in 1996 and began our new career as professional designer and manufacturer of CVT tuning parts.
Our products are mainly for vehicles equipped with CVT (continuously variable transmission) system, such as scooters, ATVs, UTVs, Go Karts and Snowmobiles. The featured products include the roller weights, slide pieces, variators, the patented sliding roller weights and HiT clutches.
We believe that quality is important to both customers and us, so we never compromise on quality. It wasn’t easy in the beginning when people tended to bargain on the price. Gratefully, after years of hard work, our products are successfully known for the supreme features as well as the outstanding durability.
