Looking at buying an S4R - need advice 
  Hi,
 
 New to the forum. I am selling my SP1 and i am currently looking at a S4R. Does anybody have any advice on what to look out for and what questions to ask?
 The bike is and 03 model listed for £4550 at a dealers. It has 12,000 miles on the clock. Does any body know when the next service is due and is it a biggy?
 
 Many thanks
 
 Nathan
