Show original supplier description

The Rapid Bike KRBRAC-129A-EX is a Racing Exclusive electronic unit designed to be a benchmark for competitive motorcycle performance. It offers advanced map capabilities with pick-up signal management for accurate and punctual control of both injection and ignition phases. This unit also provides a dual-setting feature, enabling real-time selection between two different presets for optimal engine parameter adjustment. This unit incorporates sophisticated traction control that accurately monitors acceleration and progressively limits it when it exceeds the useful range for traction, ensuring reliable performance in various driving conditions. Additionally, it includes a launch control system for perfect starts and a pace limiter to progressively and gently manage engine RPM, particularly useful in traffic situations. It is important to note that the Exclusive version of this unit cannot be reprogrammed for other bikes and does not include the USB cable required for connection to the free software. Rapid Bike recommends purchasing the cable separately to allow their technical team to provide remote assistance.
