Not sure about this one. At one stretch of the A14 at Ipswich east bound, there is a stretch of the road which produces a
pogo-ing effect on the bike so bad that it keeps my speed down to 70-ish. I can't remember it being so bad on my CBR600. Is it a suspension setup problem, or just the wheelbase 'in tune' with the undulations in the road?

Sounds like a resonance problem.
Try softening the rear suspension a little and see if that helps.
