Original quality, precision forging, wear resistance and consumption saving, stable performance, bid farewell to the jitter drive disc/blade disc: special process, optimize the Angle of bead rail, powerful start, the whole acceleration is more stable and smooth, excellent performance, increase the variable speed stability and service durability. Bridget: Accurate gram weight and high roundness make the start and acceleration more stable and bid farewell to shake. Support all kinds of gram weight choice, adjustable match performance. U-type drive flange: the U-type drive flange is made of imported composite nylon 46 with added graphene, which greatly increases heat resistance and wear resistance. Drive shaft: The surface of the shaft sleeve is treated with chrome electroplating, which not only improves the hardness, but also greatly reduces the friction resistance in the process of use, making the drive disc smoother in the process of high-speed operation. CAM/ramp plate: after ST16 steel plate is drawn by special process, the surface is nitrided to enhance surface hardness and corrosion resistance, reduce transmission wear, and improve the lifting speed frequency and overall acceleration performance. Customer notice: All the transmission products of SLITt motor need to go through the driving running-in period, in order to achieve the best effect. At the beginning of the use, remember not to start violent, violent acceleration, manned payload, mountain climbing off-road, in strict accordance with the new car use run-in standards. After running in 1000 kilometers, can drive normally! If there is any problem in the early stage of installation, please communicate with the customer service at any time. Any damage caused by undirected use is not covered by the warranty. Please kindly understand.
