Can the machine malfunction now and again please. Is there anything I'm missing on this track or is it just nailing the line dubs? Top replay isn't the best on ps4
Pretty much just hitting the line smoothly, yes. The final climb is the tricky part, I kept hitting that stupid rock that sticks out above the ramp before the little waterfall. Get your back wheel over that and hit the following ramp with your weight forward, front wheel quite high and you should be able to set yourself up for a smooth climb up the last pillar.
The big dip just after the first checkpoint is also a bit inconsistent and can kill your speed for no discernible reason.
