Stock MT-09 vs a Yoshimura full system. Sound on. 🔊 Yoshimura sent over their new AT2 Speed Series for the MT-09, so we put it on the 2025 MT-09 SP. Deeper, pops on every quickshift, and it still looks low-key. Full install and ride is up on YouTube now. Would you run this on your MT-09? @yoshimura_rd
