we need a guide writing up on this really as it gets asked a lot so do a search and you will find loads of info theres also another thread running in bike chat covering restriction the first thing i would do is check out insurance as regardless of if you are restricted the insurance dont take it in to account a V twin or a bike with lots of torque takes restriction really well as do most bikes they will all run well but for overtaking etc you need a torquey bike also think if you are planning on keeping the bike a few years and when you remove the ristriction its a bike jump and what sort of riding will you be doing?
