Like every year, we present the new developments of the 2022 season that will be introduced in the Birel ART – Freeline karts and products for the year 2023.

The acronym that characterizes the new models for 2023 will be S15.

Based on the S14 models we have further implemented and refined different technical details and we introduced new accessories to improve and simplify the use.
