I had a 2006 SV650s. I never even came close to out growing the bike, but I did always want an inline 4. I just loved the sound of it over the vtwin sound of the sv650. So I understand where he's coming from with wanting the R1. I also don't think he's all to committed to the litre over like an R6, he's just going for the R1 cause he feels he's getting a deal on that bike. Most importantly, you are the one riding and paying for it, no one else. You make the decisions as to what bike you want to buy/ride and how hard you want to twist the throttle. When I was 19, I wanted a new SUV. I way overpaid because I was so set on getting one, even against the words of family most importantly my father. Nothing anyone could have told me then would have swayed me otherwise. When I get my mind set on something, I don't care what anyone else would have said. If you TL/DR this post here's the summary: Get the bike & Enjoy.
