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

$179.00
by DH Motoring

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.
