OtomotifZone.com – Jakarta. Pada gelaran IRS setelah lebaran, akan ada kelas UB150cc. Yang mana kelas ini memang sudah akan diselenggarakan pada seri perdana 2018. Namun kala itu tidak jadi diselenggarakan. Kali ini penulis akan sedikit membahas regulasi yang diterapkan pada UB150cc.
Dari spesifikasi motor sendiri mungkin bagi kalian yang mengikuti gelaran Kejurnas sudah tidak asing. Secara garis besar regulasi hampir sama dengan kuda pacu MP1. Akan tetapi ada yang sedikit berbeda. Perbedaannya hanya regulasi rider yang mengendarai (Usia).
Pembalap yang akan turun di kelas UB150 di IRS sendiri merupakan pembalap pemula A. Atau anak-anak MP3 maksimal. Disini penyelenggara mencetuskan bahwa pembalap memiliki umur maksimal 20 tahun. Dan bagi peserta yang ingin mengikuti bisa langsung mendaftarkan diri ke pihak penyelenggara.
