It`ll get easier when you get to know the bike and how it handles on different speeds. I have been more or less on two wheels most of my short life, and I have to say that changin my last bike (125cc Cagiva freccia c12r, 308lb) to the 600CBR I`ve driven for a few weeks now (462lb) was a bit of a shock. First it felt like riding a two wheeled bus, and I just barely could push it backwards, mostly because I was **** stiff not to topple it. Now I handle it like I did the Freccia.

Oh yeah, and I`m 170cm/75kg (5`5"/165lb)
