Must say this mod has made the bike an absolute pleasure to ride. So much fun. I did order this from the uk so i had to change one pin from the ecu connector to make the revs guage work but it was so simple with the guide that David sent. If you own grom / msx125 this is a must have mod. You won't be disappointed.
Really woke the bike up. Comes alive at 6k now.
Pleased to report that the DHM Reflash and TB cam package improved everything across the board. Much better throttle response and linearity with a healthy top end that did not exist before.
Really made my grom alot faster. You can feel the powerband around 6500 rpm and my bike screams hella loud. Super happy for the purchase. Service is awesome too!
DHM Reflash and TB Cam Package
**Cams are in stock and shipping!
***If you already own a DCR or TB camshaft you can still purchase our Reflash for those mods here: https://www.dhmotoring.com/products/stage1reflash
If your Grom already has an intake and exhaust, this is the next step!
We've created a camshaft package that allows you to add a TB camshaft and our DHM Reflash to your bike. This will add as much as 2-3hp and will also increase your rev limit to 10,000 rpm, while also correcting the fuel and timing tables in your ecu. Your Grom will experience much stronger high RPM power, as well as the ability to pull to higher RPM before shifting. After tons of dyno and street testing, we feel this it the best bang for buck upgrade available!
