I loved NSRs when I rode them. They’ll keep up with the big bikes easily enough. BUT, now that I’ve owned a big bike…I won’t be going back. I’ll ride my scooter and make do until I have enough money to buy a big bike again. The NSR is speed without emotion…the CBR is speed WITH emotion. I’ve actually had tears come to my eyes a few times on big bikes…no joke.
There are plenty of roads suited to big bikes in Taiwan…you just need to know where they are (east coast mostly). For a few months I was taking my big bike to work…I was hitting 250km/hr on a bi-daily basis…just going to work. And I’m still here typing about it…didn’t get me to work much faster…but it was fun.
My bike is gone now…and I feel a little empty. I have all this money…and the only thing I want to do with it is go riding…on a bike I don’t own anymore. 
I discuss owning a big bike here: [forumosa.com/taiwan/viewtopic.ph … &postorder](Is buying a "big bike" in Taiwan stupid? Most would say yes
I hope that clears some things up.
