DHM Stage 2 Flash and S1 Cam Package (2022+ Grom / Monkey)

Clayton Morrison

It makes a big difference on every gear. Its so much fun.

Shamel Tyler
Highly recommend

After this purchase my grom bangs through the gears faster and pulls much harder, along with a top speed of 172mph. I'm 5'9 162lbs

2023 grom

After watching a few videos on how to install the parts it's fairly easy. And for me not knowing anything about motors. Does the job awesomely aswell as the best communication for any questions.

Fast delivery for a great product

Bike runs great with the cam and reflash

If your 2022 Grom/Monkey already has an intake and exhaust, this is the next step!

We've created a camshaft package that allows you to add our S1 camshaft and our DHM Reflash to your bike. This will add as much as 2-3hp and increase your rev limit to 10,000 rpm, while also correcting the fuel and timing tables in your ecu. Your Grom will experience increased power across the entire rev range, 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
  • Modified injection timing for ride ability and response
  • 13+ HP depending on your intake and exhaust setup
  • 10,000rpm rev limiter 
  • Normal cold start functions (no bad idle issues when cold)


  • DHM S1 Camshaft
  • DHM Reflash for the S1 camshaft and other modifications

You have two purchase options for delivery. Once you've completed the purchase, we will email you with instructions on sending your ECU in to be reflashed. You can also choose to purchase a core ecu, we will send you a flashed ecu and you can return your original one and receive a $75 credit or keep it as a back up.
