Hi there....
1) There is no major problem with the parts...You can find quite easy any part you like...
2) -------- Don't know --------
3) The consumption of an NSR is similar to a V12 supercharged Dodge...!!! LOL....!!!!!
4) I don't think you are going to look very good on this bike but who cares...!!! If you like it just take it...
5) It depends on the country... Here in Greece the price is quite good for a 250cc ... Ask an insurance agent...
6) Yes you can... But not for a long ride....
7) Chicks just hate it....!!!! LOL...!!! But who gives a $h$#%^ about them...!!!
You're wellcome...
Michael
