Menggunakan IHI Turbo RHB31 Yamaha R3 ini belum banyak dibuat. Hanya ada  satu satunya, tapi nantinya akan di homologasi untuk kelas baru 300cc with Turbo di CIV (sebuah ajang balapan di Italia). Ga kebayang kan kalau digunakan harian mesin 2 silinder dengan turbo guna menambahkan pasokan udara dingin dan padat ke dalam sistem pembakaran mesin.
