For the EXC models to comply with epa standards require a lot of restrictions to the bike. From what I read, there is appx 10-15 hp reduction from the ECU, the restricted intake and exhaust. There are ways around this, like the Vortex ECU replacement and then de-smoging the bike. But that's pretty expensive. https://blaisracingservices.com/vortex-racing-ecu-for-2017-ktm-350/500-exc-husqvarna-fe-350/501-models.htmlCurious why this would be a better DS platform than the EXC-F? I love KTM but the models always seem very similar and hidden behind HD type lettering schemes.
