Kawasaki Ninja 400 SSP300 - Raw telemetry, Circuito de Cartagena, wet and dry acquisition days

Raw on-vehicle telemetry from a Kawasaki Ninja 400 (model year 2018, 399 cm3 parallel twin) prepared to World Supersport 300 class specification, recorded at the Circuito de Cartagena (Cartagena, Murcia, Spain) on 19 and 20 September 2026 with one rider and one machine. The depositor reports rain, a wet track and rain tyres on Saturday 19 September, and sunny conditions at approximately 26 degC on Sunday 20 September; these conditions and dates are external session metadata because the log headers contain no wall-clock reference. The release contains 64 unique publication payloads, 30,867 reconstructed records and 3,089.8 s (0.86 h) of logged time from an open-architecture STM32H723 datalogger. It includes Mektronic-family ECU channels over CAN, ECU-forwarded GPS, SHA-256 raw manifests, channel and integrity audits, a reference decoder, and convenience update-stream and reconstructed-state CSV files. Six supplied files were excluded because they are exact copies already published in the Circuito de Navarra record 10.5281/zenodo.22755547. Two additional supplied files contained exact published Navarra prefixes followed by Cartagena records; the release removes those prefixes and 124 seam bytes and retains only the Cartagena suffixes from valid MBL frame boundaries. Documented limitations include absent wall-clock time, GPS outliers, right-censoring at the 106.27 bar front-brake channel ceiling on Saturday, and a single-rider single-machine design.
