Very similar the 350 revs faster 390 might have just a little bit more torque off bottom. Both bikes run great. The 350 exc is becoming one of my favorite bikes ever.
I have a 21 350, get ecu and full fmf system. The bike is great but I ride from my house to get to the trails and it feels like it’s going to fall apart at 55 60, crazy vibration. I was considering beta 390 or 500 but seems the 390 might be in the same boat.
I dual sport the 350 a lot. It definitely isn’t the best on the highway. I run about 55-60. It doesn’t bother me to much. I just don’t plan on long stretches of pavement. I think the most pavement I’ve done at one time on it is 25 or so miles. I owned a beta 500 in the past and loved that bike it was better on pavement. Still a Dirtbike though so it’s not ideal.
Think I’m gonna just get my suspension done and a second set of wheels and tires (balanced & taller gearing) with better road manners for the two track stuff. Appreciate the response, like the vids 👍
