Quite a bit punchier

Easy install, works as advertised, and the good old butt Dyno really feels the power!

Definitely impressed 😁

Before the cam & tune I was having issues with wind and small inclines slowing me to 50mph on flats I could hit 60.. but now I'm hitting 65-70 with wind and inclines ain't no worries 😁 I was skeptical. If only I had done this 9k miles ago

Great upgrade

If you are looking for an upgrade to wake up the Grom then this is it! It really woke the bike up. Gained power and top speed. Highly recommend. Great product and Great customer service.

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! 

Features:

  • 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)

Included:

  • 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.
