Even if I lose the sale...I believe an RT model would be more suited for him. The position of the RS is going to be tough.
But that RS riding position might be what he's after?? :sour: Still, as others have said, good on you for being concerned, but really, it is his choice isn't it?? Maybe (tactfully) express your concerns about this to him & see how he responds? And don't forget that there are already more than just a couple of RS riders around who are around the same age as him (or possibly even older!) and they might look a little frail or fragile while walking, but those I know personally can be damned hard to keep up with once they've managed to struggle aboard!! :yikes:
So sure, express your concern, (maybe even ask check his licence?
) but unless he's clearly incapable of riding &/or making a decision about what he wants to do in his Golden Years, it is
HIS decision to do what he will/buy what he likes. This can be one of the hardest things for kids & carers to come to terms with about their Parents &/or charges; but you can't stop them doing things just because you feel it might be risky for them.... And you are arguably in a far less 'responsible' position than his children or carers - It is
HIS life, what's left of it is his to do with as he will, isn't it?? Doesn't your Constitution guarantee him that right?
Besides, if you tell him he can't buy or ride
your Spyder cos '
he's too old & fragile for it', even if you word it much nicer than that, there's still a good chance that'll be like a red rag to a bull, & he might be angry enough to go out there & buy/ride something even more unsuitable & dangerous - and if/when he stacks
that, won't you feel just as responsible for forcing him into a really bad decision, for not giving him a chance at riding something that might've been a little better suited & safer, even if possibly not quite the
most suitable?? (In your opinion,anyway??)
State your concerns to him as tactfully as you can, but if he's old enough & legally allowed to do this, then if he's got the $$ surely you gotta leave the final choice up to him!?! I know I'd want to be accorded that courtesy when I'm 89; I sure as heck demand that courtesy now, despite having some mobility issues that many would consider very similar to what you've told us of his!! Give him a go, it could be the last thing he needs to tick off on his bucket list.... or maybe it's just another milestone in an already exciting life! :thumbup:
, don't fret. I will have died happy.
