This cam made a huge difference, very happy with the performance, plus David was very helpful and responsive to emails
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
