Sometimes the differences do not matter to most people, but they matter a lot to some.
Take the difference between a Porsche GT3 RS and a Porsche GT3 RS MR (Manthey Racing). You take a really, really fast car, and Manthey (Porscheâs equivalent of AMG) does literally nothing to the engine, rips out exquisite Porsche parts and replaces them with even better ones. Even though they only upgrade suspension, aero and the like, the result is a car that is significantly faster on the track. Can you feel the difference on the road? Most people wonât, especially if they stick to local traffic laws.
And even in the regular GT3 RS, in most jurisdictions you are at most 4â5 seconds away from losing your license.
There is also a difference between ordinary cars and race cars, which I think is an apt comparison if you look at super bikes. The suspension of a BMW M3 is perfectly adequate for what it is designed to do, but if you were serious about racing or taking it to the track, youâd probably want to rip it out and replace it with something proper.
Sure there is. Whether this difference matters to you is another thing.
I had what I consider a super bike (although I reckon itâd be a high-end bike according to your classification) as a loaner for two weeks, and I knocked off 2:45 minutes off of my PR in a 22-minute climb. And I didnât even have a power meter on that bike to pace my effort properly. This thing was a hoot to ride, the frame and carbon rims were not just supremely comfortable, but also confidence inspiring.
And while I am fast when compared to most, Iâm slow when compared with properly fast people. (Iâve ridden with former international pros and current domestic pros, I am under no illusions
) Proper pros will be able to do things with a high-end bike that they cannot do as well with a cheaper bike. Because at the highest of high-ends, a lot is about marginal gains. Thatâs how pros choose their gearing, thatâs how they approach other aspects.
I know someone who bought a decked out Pinarello F12 because thatâs what they favorite team in the TdF used. He isnât the fastest to put it mildly, but the bike puts a smile to his face when he rides it. So according to me, it was a good investment for him.
