The bike runs great! It's an easy fun upgrade
the motorcycle runs great and the turn around time was great
Awesome product, easy to install and turn around time was fast. Biggest bang for your buck on a performance outlook. Definitely recommend this product.
I was running stage one with a out Ex exhaust and a foam filter. Now added a mnnthbox intake, TB cam and stage 2 tune. Gained over 10 mph top speed and bike gets to cruise speed so much easier. Thanks DHM 👍🏻
Just want to say thanks to the team at dhm the stage 2 kit with tb cam has really woken up my 2016 sf grom stoked with the mid-top end power also sounds a treat
Will definitely come back great service easy install 👍
**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
****DOES NOT FIT THE 2022+ HONDA GROM/MONKEY
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!
Corrected Air/Fuel ratio for your exact modifications
Increased ignition timing for throttle response and HP
13+ HP depending on your intake and exhaust setup
10,000rpm rev limiter
Normal cold start functions (no bad idle issues when cold)
