Details
The science behind the Megabomb header may be FMF’s greatest engineering accomplishment to date. You can bolt on a Megabomb with an existing FMF Racing slip on for as much as a 3hp boost, plus the Megabomb actually reduces noises levels by as much as 1.5dB. The Megabomb technology is revolved to produce more low end to mid-range gains as well as broadening out the mid to top end power gains over stock. The Megabomb is best used for Motocross/Supercross and GNCC style trails. Used by Factory Teams, the Megabomb is the next level technology you can have today.
- Produces long header torque and short header over-rev.
- Reduces sound output as much as 1.5dB.
- Increases output from stock motor as much as 3hp.
