If your 2022-2025 Grom/Monkey/Dax already has an intake and exhaust, this is the next step!
We've created a camshaft package that allows you to add our S1 camshaft and our DHM Reflash to your bike. This will add as much as 2-3hp and increase your rev limit to 10,000 rpm, while also correcting the fuel and timing tables in your ecu. Your Grom will experience increased power across the entire rev range, as well as the ability to pull to higher RPM before shifting. After tons of dyno and street testing, we feel this it the best bang for buck upgrade available!
Features:
Corrected Air/Fuel ratio for your exact modifications
Increased ignition timing for throttle response and HP
Modified injection timing for ride ability and response
13+ HP depending on your intake and exhaust setup
10,000rpm rev limiter
Normal cold start functions (no bad idle issues when cold)
Included:
DHM S1 Camshaft
DHM Reflash for the S1 camshaft and other modifications
***Each tune is catered to your exact modifications (intake, exhaust and cam brands, etc.) After checkout you will receive a link to an online form that will ask for your bike's exact setup so we can tune it accordingly.
You have two purchase options for delivery. Once you've completed the purchase, we will email you with instructions on sending your ECU in to be reflashed. You can also choose to purchase a core ecu, we will send you a flashed ecu and you can return your original one and receive a $65 credit or keep it as a back up.
Easy install no issues super fast turn around on shipping. Highly recommend

Fantastic, way more pep
Cam was relatively easy to change, bike has significantly more torque. Wish USPS was a shipping option though, UPS is expensive for international and they charge brokerage on top of the fee.

Noticeable differences
Finally my from has woke up. Adding the s1 cam and s2 flash has made big improvements all around. Very satisfied with the results.

S1 and tune
My support mods are not the best for performance. I have the Takegawa SP exhaust and a Decha tube with stock lid. The bike did exceed 55 mph on small hills so it was a win but the exhaust was a bit loud for my taste. Down side was exceeded 55 but in 4th gear. 5th was punier than stock and basically worthless. If you’re looking to rip around on a 55 mph mod this will do it. If you just want to add a few mph but like stock this isn’t quite there. I have 500 miles on it and have boxed it up and gone back to stock. I will try again one day when 5th gear isn’t excluded from the gains
