I can’t remember a lot of things but I do retain arcane details such as the R1 fuel tank was lowered a bit and ergos adjusted in 2000, for increased comfort, and that they made first gear a little taller… and some other stuff. Various studies have found that riding motorcycles really does keep you sharp, as it requires you to call survival instincts into play that non-riders just don’t. Going beyond that, not having traction control or ABS even requires you to remember not to suddenly whack the throttle or slam on the brakes, and hones what I like to call your “fine survival skills,” which also includes things such as not playing harmonica at the table and not grabbing people by the p***y.
