I think we all know short starts are not great, but as a general rule, any vehicle I have ever had that has been laid up for any amount of time has basically deteriorated. Cars more than bikes to be fair, but vehicles generally like to be driven/ridden. cars go mouldy, rubber manifolds and intakes dry out and crack, electric windows stop working. I think things just like to be used to keep them in good order. I think if I was taking a bike off the road for the winter I would do what my neighbour does, he keeps his three main bikes in his living room, each chair has a bike behind it. At least you know it will stay warm then. Mine lives outside, and I make myself go for a good long ride, even if I don't need to, at least once a month. I actually find it a good excuse to make me go for a ride, which I enjoy, whereas, otherwise, I might just not bother.
