And at your age you’re a better candidate for Litre Duc ownership that a 20-something beginner. Keep practicing with your mentor, but get some professional coaching ASAP. The MSF course is great for teaching people how to ride 250cc cruisers in parking lots, but does not prepare people for riding liter bikes in the real world of traffic lights, dogs, gravel in turns, and cars turning left without signaling.
Street survival requires handling emergencies. Do you know what to do if you keep your wrist a bit too high and find your bike getting away from your? How will you handle entering a blind corner and finding gravel at the apex? Do you know how to stop a bike quickly without locking the front wheel?
These are skills we all need. You can develop them on a large bike if you are careful and have good coaching, and as large bikes go your Ducati GT1000 is particularly benign. We’re talking about a lightly stressed twin here, not a Yamaha R1. And I know you’ll be careful, because the GT1000 is just too pretty to deface.
