D., you must live in a high crime area. Someone stole the engines! Kidding aside, I am impressed you can (at your advanced age

)still ride a bike. You must still have good knees. No way can I ride one anymore, knees just won't take it. Of course, even if that were not the case, bikes no matter how fancy, are just too slow and boring
for me. I'd fall asleep riding. Top speed on the Benelli's is a little over 60 at 10,000 RPM. On the dirt roads you probably can or do go as fast as us.....20 mph or so most of the time.
Happy New Year!
