Ash77

ive had my sv since march this year after passing my test. its been great and ive done about 2.5k miles on it on wkends etc. i'll have 1 yrs no claims in march 09 so then might be the time to upgrade. i was thinking of a gsxr750 k6/ninja 636 finances permitting. i might also be tempted by a fireblade. i dont really want to have to thrash a bike to make good progress. are 4cyls like this a good upgrade choice?

i dont want high running costs either so am put off by an aprillia 1000 twin etc. im open to a more upright position but dont really mind.
it has to have at least 90bhp and weigh under 200kg.

is a 4cyl the next thing to have and if so which are the most rounded?

if i put mine up for sale in the next few months it will have about 15k miles and is a napoleon blue, half faired, scorpion can, datatool, june 2006 model in good nik. whats a fair price for it?

cheers, ash
