Further to the above, knowledge is power. I'm happy to admit I'm no expert, but I'm often shocked at trackdays how little people know about their bikes, suspension especially. I'm not talking about the finer intricacies just simple stuff like setting sags, which end of the shock/forks is compression/rebound, and what they do etc. Folks rock up with a near new 180hp GSZXR1000RRRR and have no idea about tyre pressures and volunteer their bikes to be "set up" by the tutor because they haven't the faintest idea where to start. Not having a crack at anyone, we've all started somewhere, just highlighting that people want more without even understanding or maximising what they have.
My old '06 R1 (purtiest japanese bike ever) roadie is a classic example: GYTR slip ons, de-catted link pipe, PClll, BMC filter, no rocketship but still 160-ish rwhp(?)....but just an absolute pig of a thing on the test ride, no wonder the owner was flogging it and keeping their GSXR600. All the same, it was in great low mile condition so I picked it up. Turned out the front rebound was at almost minimum, way too much compression damping, with the shock almost the exact opposite. So the poor thing gave you no compliance whatsoever entering a corner, would then pop back up as soon as you got off the brakes/tipped in, while the rear would squat with a sniff of throttle and just stay there on exit, packing over bumps etc....just horrible. The hairs on the back of my neck stand up just thinking about someone trying to push it along a bumpy country road or on a track day. But an hour after getting it home it was the sweet ride it always should have been, and I certainly don't yearn for any "more", "go directly to jail" is fast enough for me.
