The DHM team is amazing, offering the best premium parts you can find online. I installed the intake, exhaust, and DHM tune, and I was blown away by how well my 2025 Grom ran. Then I decided to push the limits of power without going with a big bore kit, so I pulled the trigger on the DHM Stage 3 — and it feels like a brand-new bike! After my purchase, I was so excited I couldn’t sleep, so I emailed the DHM team to request overnight shipping for my kit once they received my ECU. They communicated exceptionally well, I paid the extra shipping cost, and they made it happen. For reference, I placed my order on Monday, and by Thursday night, I was already installing parts.
