Riding around on 2-wheels; whether it's on my sportbike or even riding my DH MTB just for fun around the area, it's enjoyable. Brings a smile to my face. <-- this doesn't happen very much.
Did a 110km loop on the motorbike today to further practise skills. On the straight secteurs when I was stuck behind other cars (with no one behind me, of course), I just experimented/practised shifting my weight around to feel the effects. Even dared myself to take "the difficult road" back down and it went very smoothly.
