24’ Grom ABS, Ridin “mean” with the stage 2 DHM ECU tune and S1 camshaft. You can feel the power. I didn’t wait too long to get it installed. It has a good amount of increase in power and acceleration. A must have when looking for a little “ooomph”!! Definitely worth the purchase!
Works great with 149cc kit, and ecu reflash
Gives power across full rpm range, I have noticed that it has more power and I’ll have to drop in gear as much as I used to. Also is nice when going through twisties that I can rev out higher.
After installing the DHM stage 2 parts my Monkey woke up like a crazy Monkey lol. Definitely a game changer.Thanks to David for the fast communication and answered all
I couldn’t be happier with the product not to mention the service:
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
