The front suspension boasts a 40 mm upside-down fork with 120 mm of travel, providing excellent feedback and control, while the rear suspension, featuring a double reinforced member aluminum swingarm, ensures a smooth ride even on bumpy roads. With a fuel tank capacity of 14.50 liters, riders can enjoy longer rides without frequent stops for refueling. Aesthetically, the RS 50 is offered in vibrant color options of red, white, and black, ensuring that it stands out in any crowd. The electric starter ensures easy ignition, making it convenient for quick getaways. **
