I will try to explain my thoughts.
I started my way into extreme enduro 3 or 4 years ago, it was Husky 125. I reached some level, but I don't aspire to be professional. The first thing I started to learn is logs and tires. Here is an earlier video.

Then I go for hills and less technical obstacles. And I bought 300... and at this moment I do not understand why I did it. In fact, I stopped in progress.
Analyzing the same track two years ago at 125 and now at 300 - I concluded that I was going almost identical.

Moreover, for 300 I can not make big logs and tires, I just can't do it. On the other hand, I kind of became lazy and relaxed, realizing that the same obstacles are given to me because of the enormous potential of the engine. And how much I tried to raise the bar - it just doesn't work out for me.
I came across different technical problems of the motorcycle, eliminated them, but it did not affect my ride.
So the main idea is that something is wrong with my 300 ... I am unable to drive it effectively.
And I think to go back to 125 - the time when I easily practiced (300 exhausts me very much) and progressed every workout.
The second thing is - I want to change my EC300 2011 for 125 2015 - 2017, as I was told new motorcycles go differently and better. I would like to buy something 300cc 2018, but I can not afford it.
So I think it is better to drive on a less powerful but newer motorcycle than on the old one, and one that does not make progress.
