I'm about to turn 50 years old and I've decided to take my bike test. I had a scooter for 3 years then a Yamaha DT125R for 4 years but got rid as I got fed up with taking my CBT every 2 years ( been driving a car for 37 years). I'm half decided on 690 Duke or the 790 Duke I'm swaying in favour of the 790 as I don't want to outgrow it quickly as I feel I may do with a 690 and at some point my wife will be coming out on the back and thought the 690 would be a bit small. I class myself as a sensible driver/rider but my main concern is will it be too big and powerful for a first 'proper' bike? Any advise and views would be greatly appreciated. Thanks.
