Well if money is not too limited then, just get one of the upright position travel enduro's (or Adv's sometimes called). Yamaha Super Tenere 1200, Kawasaki Versys 1000, Aprilia Caponard 1200, Triumph Explorer 1200, Triumph Tiger 800, BMW S1000XR, KTM Adv 1190, KTM Super Adv 1290, Ducati Multistrada 1200.
Of all the above, CT8, and based on your posts here I think the BMW S1000XR is the one for you... inline 4 but far from boring !!
You can have a lot of fun with any of the above.
