I hope I am still riding at your age and beyond.
I'm 60 and also just want to ride. Back in the day I was always pulling my bikes to bits to clean and replace steering head bearings with roller bearings, and swing arm bushes got replaced often on my old bikes etc etc.
I like the 919, I test rode a Z900RS last week and wasn't impressed at all,
the local Honda shop just got in a new Honda CB1000R, so have my name down to give that a go.
