Roche Machines was a manufacturer of Verpine airspeeders responsible for the creation of the V-4 series, which included the V-4X-D ski speeder. Following the unfortunate events of the Orleon Belt Grand Slalom Finals, Roche Machines halted the manufacturing of the V-4 series and liquidated their remaining stock at significantly reduced prices due to a sharp decline in orders.
