When did riders stop saying "You can take if for a spin if you want!"

[SIR REAL ED]

I remember when you were looking at someone's bike, and the owner often offered you the opportunity to "take it for a spin!" 

Going all the waaaaay back to the olden days when the first reply was almost always: "Cool.  OK.  What's the shift pattern?"

It used to be great fun to go on a group ride an swap bikes!

Now if you offer to let someone ride your bike, they look at you like you offered them the opportunity to sleep with your daughter!  And of course the shocked person will never return the offer.

Was it due to:  A change in humanity?  Insurance regulations?  Hyper performance bikes?  Expensive bikes? Or people just worshipping their motorcycles as "personal shrines of perfection" and fearing the other rider might violate their bike's virginity/perfection?

In my experience this practice became uncommon in the late 1990's.

I still do it, especially with the Convert.

Nobody's exactly keen to ride my 400 pound 20 horsepower beast.

Between all my neighbors and coworkers, there are only two other riders. One of them is too immature to trust. The other did get a chance to ride my dr650 and I've offered him my guzzi when his bike was broke. He declined.

I swap bikes with my buddies

[Moparnut72]

I will let another rider I know to ride my bike. I won't ride theirs when it is offered. I don't want to screw up and be obligated to fix whatever I broke or damaged. I don't worry about mine though, everything is fixable.

For me its just never really comes up. My friends usually don't ask to ride my bikes and I don't ask to ride theirs for reason Moparnut72 stated. I guess we just don't want to put anybody in a bad situation.

I was shocked last year when an another rider wanted to ride my V7 Special and offered to let me ride his Ducati V4 Panigali.  So we instantly swapped.  After riding he commented that the Guzzi was "interesting."  I ran into him (not literally) a few months later.  He told me he sold the Panigali.   To buy a Guzzi?  Nope, he bought a new Panigali because the current version has 220+HP and his ONLY had 207 HP (!!!).  Young guy?  Nope, mid 70's.

I still do it with riders I know.

I offer my mini motos (<125cc) up for almost anyone to ride. They're approachable, light, slow, and cheap. Low risk. For bigger bikes I offer to let folks ride them if they've ridden something similar enough and I think they won't drop it lol. I've been leant other bikes and unless they were something I've ridden before it's been a nice but slightly uncomfortable situation with the discomfort being me worrying more than taking a brand or dealership's demo bike out. I've declined offers to ride bikes that had vastly different controls (antiques) or were pricey bikes beyond $30k in value. Other than the mini motos, it doesn't come up often.
