stop messing around, get yourself on the road and it'll give you motivation to pay off any loan. by the time you'd saved for the nsr something else will pop up and the money will be gone. plus if you buy now you'll save money cos decent bikes go up all the time...the chinese want nsrs too.
this time next summer you'll have oily fingers, nsr knowledge coming out your ears on a bike you know, you would have earnt your crust and will be living the dream and looking out for your next se/sp purchase.
