After lots of discussions i went for
Yamaha XT660x. Pretend Supermoto.
Has a tank range of 170miles, weighs less than a modern 600 supersports and is a big noisy single cylinder. Built by the Japanese too, so servicing costs etc should be low.
The bike is truely great. Proprt proper fun tool. Comfy up to 90mph and tops out about 105mph. It's far from being the quickest thing in the world, but is a blast to ride and handles like a dream.
It has many things in common with KTM's namely hunting/fuelling issues it's crap at 30mph LOL. However doesn't bother me, as it's not common for me to be in town etc.
Picked it up for £2500 on an 06 plate with 1300 miles on the clocks... BARGAIN !
Just thought i'd update you lads
