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.
Easy to install and runs great. After install the grom fired right up and runs, idles perfect. Revs way stronger and picked up top end in the process. Top speed 74mph by gps. If I can do the swap anyone can. Made a big difference on a small bike.

5th Gear
Every gear is great except for 5th. It falls flat and has no acceleration in 5th just like before the flash and cam.

S1 cam
Love this cam, a very well rounded cam and definitely well worth it. Would definitely be getting more for my other motors
