Mine is a 1540cc, but I think the newer model is 1640, but a mate of mine has his bored out to 2.0ltr. Far from being the fastest thing on 2 wheels like, but it does me mate and it'll run all day at 90mph and tops out just over 110mph, but at that speed they're not a comfortable ride anyway. In fact anything above 80mph and they start becoming hard work due to too much vibration and the riding position means you're copping for a **** load of wind on your chest and head. It still puts a great big daft grin on my face when I fire it up though.
Nah, I think they do a 750cc then a 1200cc then it's up to the bigger bikes which now start at 1690cc for a 'Softail' and they weigh in at 320kg, but the bigger touring bikes are heavier and a bit like riding a sofa down the road
