DHM S1 Camshaft for the 2022+ Honda Grom / Monkey (Generation 2)

$179.00

After testing multiple different variations of cams for the 2022 Grom, we've settled on this setup for stock bore and big bore bikes. We have maximized the lift using the stock valves and combined that with a very rideable duration that produces gains at every RPM in the rev range. 

DHM S1 Camshaft

  • Highest possible lift with stock valves
  • Gains across the entire rev range
  • +1-2HP over a bike with only intake/exhaust
  • Direct drop-in installation
  • Set valve clearance to .005” / .005”

Generation 2 Updates

  • Removable big bearing for ease of install
  • Duration adjustment to help tip in response and idle noise
  • Stronger heat treatment to increase overall durability

A tune is required to run this cam! We have our ECU flash available HERE and we also offer the aRacer Mini5 if you prefer to do the tuning yourself, available HERE.

DHM S1 Cam

Generally i do not write reviews but this is the little cam that can!
I have the Deca air intake and the TST airbox cover supplied by DHM. Leo Vince exhaust. -eBay Special
My bike is a Euro bike so had to use the powervision 3 to map the S1 Cam and fortunately the PV3 came with a map with 90% of my mods winner.
Out the box the cam just rips, Hills on the Isle of man aren’t Grom friendly - Hills that i use to ping between 3-4th gear about 50mph are now hills i sit in 4th, it now pulls like it should. 400rpm higher on the map i didn’t think would make much difference does! Install is easy. Just awaiting the next Grom ride out to put it head to head with others!
I still cant get over the speed of delivery - From the US to the IoM quicker than parcels take from the Uk to IoM! Less than 7 days on the last lot.

This change my bike

Ebay exhaust. Decha performance stealth intake with TST Worx Lid and KN filter. But nothing added as much power as this DHM S1 Camshaft. Bike feels like a mini beast now. Each step with the appropriate ECU tunes (dynojet vision 3 eu) Great fun

The camshaft upgrade along with the ecu reflash really woke the bikes powerband.
