if it had been an r1 then it might have been the equivelent of passing your test in a robin reliant,then going out and buying a lambourgini.
as its an fz1,still quite a bit of differance in power considering you recently passed your test,but its not to big a step up so you should be fine.
ps didnt meen to make it sound like an sv was like a reliant,there great bikes i luv mine.
