i have always had jap bikes, and in a moment of apparent insanity decided to try a ducati. i am glad i did,the bike has somthing you dont get from jap bikes. i cant realy explian it, but when you start it up all that mechanical clatter and thumping v twin vibe,there,s just more sense of ocasion. starting some jap bikes is no more exciting than starting a lawn mower.dont get me wrong jap bikes are very good but riding my duke makes me understand what people mean when they say it,s got soul.my bike didn,t come with service history which is potentialy a big mistake with a duke.when i took mine to an indepndant duke specialist it cost me £500 for an engine service and a couple of other miner service items.the st4 leans more towards the sport side than touring with regards to riding position and it,s handling abilities, but its still a very comfy ride long or short distance.mine came fitted with a top box which is a good thing because there,s not much space to keep anything without one. under seat storage is reserved for the tool kit only so i leave that at home and take a pressure gauge and a couple other small items in it,s place.i have just fitted some ducati sport exhausts and it sounds great.it,s a joy to ride what ever mood your in whether you just want a steady ride to youre favourite destination or showing sports bikes the way down youre favorite set of twisties.i dont think i will ever go back to four cylinders,that v twin grunt and good spread of power up to the rev limiter make me feel iv,e been missing out on somthing all my jap bike riding years.A couple of minor gripes, standard screen not tall enough for decent weather protection and a heavy clutch lever.with regards to the cluch i was advised to try clutch springs from a 748 which only made a small difference but still worth while. by with confidance if it,s got service history, but dont pay good money for some thing without it because it could be expensive when you do get it serviced
