Good start mate. Yeah lift the camera angle a little and work on the wind noise.
Welcome to the community
A few of my thoughts (just my opinion, not implying too much value on them, lol):
1. Nice intro vid - a good length - under 10 mins is a charm - especially when starting out.
2. Watch and really comment on the motovloggers stuff that you like - there's no short cut into the community (many have tried, never works unless they constantly crash, wheelie or start fights... not my sorta scene and hard to maintain!). When people see your input in the form of commenting on their vids they will start to check you out, and then so will their subs, and your network & audience will grow.
3. Avoid setting a schedule (like once a week). What if you're busy, not into it, nothing happens... etc. etc. The danger is that you will then upload for the sake of it and it may not be popular.
4. Make sure you enjoy it. As with any form of entertainment, the mood of the entertainer is immediately reflected in, and onto, the viewer. (unless of course you are being hurt, failing terrible at something or being publicly embarrassed, in which case it will go viral

)
Good luck buddy, this can be a lot of fun
