MM, what is your opinion of the 350 vs the 390? Everyone says the 390 lugs better but can’t imagine a 350 really lacking in low end power compared to a 300 2T. I’m just curious why you think most disregard the 350. Thanks

I prefer the 350 it revs better and I think its smoother. The 350 has ample bottom end it really pulls well off the bottom. I don't know why people disregard the 350 I guess as a trail bike the 390 is easier to ride as a racer the 350 has plenty for me. I'm sure I could get used to the 390 though! b
But seat of the pants I love the 350.

I have a 16 350 and a 17 390. If I'm out for fun and ripping around I like the torque of the 390, but if I'm racing I lean toward the 350. It feels lighter, has more power than you need and doesn't wear you out with the low end in tighter trail. Open fire road, sure the 390. The more technical it gets the 350 is quicker late in a ride.

Thinking about selling both and trying an 18. Not sure 350/390 as I race a 300. The 4t is just for fun.

I return on this topic, from April I bought a new RR390 racing my2018, comparing it to my previous RR390 2017 I find a clear difference in the delivery of the power, to have the same power of the previous one 17, I have to turn much morethe trottle, for example in 18 I struggle to raise the wheel.

also I noticed that the My 18 work more hot that 17 often I have the fan on.

Since in my 2019 Beta replace the throttle and made a new mapping, I was wondering if any of you did this test remapping with 2019 and new gas command.

thankyou

P.S.due to my poor English hope it is clear what I have wrote.
