2023 monkey grunt

Our 2023 monkey, we installed the cam today. Now can hit 70mph and the mid range is much more improved. Have intake and full akrapovic with minix and af2. All pairs well and very straightforward install. Recommend.

Monkey business

Edges on the camb lob is not smoothen out they are really sharp directly from machining. Elsewise it was a perfect fit. Not yet testdriven.

Another great product from David and Team!

I have so many parts from David, and the reaosn for this is that not only do you buy a product but you get his support.. Anytime Ive ever had any questions, queries or even a problem, David is there to reply, help and solve! This Cam is a super simple upgrade to your std cam, is extremely easy to fit but be aware you will need an ECU refleash or ARacer etc to adjust the timing etc.... Great product, I have one in both my race and road Grom..

This cam made a huge difference

I have a 2023 grom, and was a little disappointed in the initial performance of it from the factory. I’m a skinny guy at 140lbs and was topping it out at 54mph. After changing the cam,intake, and exhaust and adding DHMs ecu tune, it’s like riding a completely different bike. Highly recommend this company and this cam. Dave is very helpful with any questions and very quick to respond. Shipping time and turnaround was very quick. Sent my ecu out on a Tuesday and was riding again on a Saturday.

DHM Cam awsome

The new Cam just added more life to the engine...it runs better than ever!

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.
