I sold my Guzzi California 1100 at 71, but the SV stays until I physically (or mentally!) can't ride any more. They(?) say you don't stop doing stuff when you get old, you get old when you stop. And stopping doing trackdays has definitely had a mental effect, but luckily building speakers and amps, which I have done for longer (50 years now) has given me something to keep getting my teeth into. Being retired makes it hard to keep motivated and moving.
I no longer look at bike mags, too, but fortunately my wife has become almost as passionate about MotoGP as I am, so we share that, We rode to Mugello once, and went to Donington once (horrible compared to Mugello), so we both have a feel for it. I'm lucky, as my wife properly got me into music, and I got her into bikes.
Although my parents both rode (scooter and moped) for a while, and an uncle ran a bike school, I had a bike at 16 for only one year, and never rode again until '92, when I took my bike test, aged 43, And did my first trackday aged 51! Reading back my posts, it might almost sound like I am a good trackday rider; I'm really not, just done quite a few and learnt a bit, but was always inconsistent. And usually had the slowest bike. But a faster bike, a '93 Blade, just gave me concussion and several fractures, So I went back to an SV, but one with a 700cc engine and race exhaust system. I managed to redline it in 6th only once, at the new Anglesey, so that might, just, be 140, but maybe not, but never faster than that. But going round Gerrards kneedown most of the way is fun enough for me. And having to hit the throttle at the bottom of Paddock Hill to stop the forks bottoming, too. Mind you, the 'Ring as my first trackday almost killed me. Over the grass at Adenauer Forst and NOT crashing was a bit too exciting. Have a look at the You Tube videos there, if you haven't already.
The pleasure I have had, and hope to continue to have, has outweighed the pain by a good margin, despite there being too much of the latter.
So I ain't stopping until forced to. Probably by my wrists!
