I agree with you that we are never to old to do something we like .......
I stopped motorcycling at the age of +-55 years and I have had before a lot of motorcycles.
When I retired at 65 years ,I started with the conversion of the Midas ....and the love of motorcycles was back again.
I wanted an old 1 -cylindre and I bought me a restored Ducati scrambler 350 cc 1970 .
The 1 cylindre motorcycles are known for the danger of the kickstarter but if you know the methode to start and you have good boots .....no problem .
But I was so excited to start the engine ..........that I forgot the right procedure and the boots ....
Maybe I follow your idea and buy me a motorcycle with an electric kickstarter
