Thank you, I wonder if the r65 could follow in the bends?
An R65 would have little trouble following. It's such a wonderfully maneuverable bike that the turns are the least of its troubles. It is following in the straights, where the power (and braking) of the bigger, more modern bikes, gives them a big advantage, that the R65 would have a hard time keeping up.
I had some friends visiting last weekend for the MotoGP at Laguna Seca. On Saturday we went riding in the local mountains. I chose to ride the R65 even though I could have ridden my R1200ST, which would have evened things out with the guys on a Kawasaki and a couple Ducatis. However, I had no problem staying out in front of them all day long. (Knowing the roads better helps too.) On tight roads, beyond a fairly low number, raw horsepower is useless.
