Deffo test drive one, and try and do one of those off-road day as well as they are great fun and a very different slant on the biking thing. Personally I don't like single 4-strokes over 350-400cc, well not on road at least. The SV engine is brilliant in town, has plenty of pull and can be driven around under 5k rpm all day plus it has a nice top end when you need it to overtake those supermotos from the lights
