I guess this is all very subjective. Kleins of the early 90s variety are in no way 'bad' bikes. For what they are, they excel.
They are race proven, say no more.
So I guess I am going to opt for an S-Bike.
Lovely to look at, but nothing there to make it shine as an off road machine.
I will be predictable with the car, again a Miura.
I would have it fettled ridiculously to make it truly biddable, and would use it every day. No matter how big the chiropractor bill. A love affair I have never grown tired of.
