You're comparing apples to Zuchini's...
Suspension is built to a price point, generally the lowest, that will meet minimum liability criteria for hauling 380lbs of ass around on a public road.
Fuel Injection mapping is done to meet government mandated Rules & Regulations period. The bikes are not allowed to run in a manner that is stoichiometric let alone ideally tuned for performance. They are forced to breathe in a manner that abides by the testing methods placed upon them each government they are tested through. This is where Fi really shines because they can force the bike to do things that would not be possible in normal atmospheric conditions with Constant Velocity carbs. It allows them to richen or lean out the mixture at any rpm, throttle position, engine temp, run time, pressure, vacuum or really any variable defined by any sensor or moving part on the bike.
While it's true the they cut costs where they can, there's two sides to the story.
I'll use a more common example. Ford once used the same engine for boats, trucks and cars. Chevy did the same. They get economies of scale and that's why we have so many features on a modern car that just weren't there before.
Go back to the 50's and 60's and look at how many cars had A/C, power disk brakes, etc...
It's when they produce things in the millions to 10's of millions that you really start seeing the benefit.
I went to a store to buy something, they were out of stock. I went to another store that had a 2nd rate version of the same and I complained that it didn't work. They responded with "we don't have the shelf space for everything"... I left saying it takes just as much shelf space to sell the 2nd rate version as it does the version that actually works.
Just as much as you can spend 2 hours on a math problem and still get it wrong, so to can a company build something that doesn't serve the customer as well.
I was pricing what it would take me to manufacture a product. One of the key issues is adding more stuff into the base design that increases the value. This is a critical part of the design process. Just as Ford used the same starter one a whole bunch of cars and trucks... this increases the value to the consumer.
The amount of time and effort it take Honda to make or Apple to make 10 million electronic boards (for a phone or an EFI) is not going to change much by adding $0.03 worth of connectors for a USB or flash drive.
I can get a whole computer for $9 retail. Your telling me that $9 retail would have cost Honda so many sales that they just couldn't do it? BS. (By the way, the $9 is for a fully functional computer at retail price). Honda or Apple could add in the storage port for maybe $1 in parts.
Suggesting this is all about keeping the price low doesn't fly.
If that theory were true, how does Samsung do it? I have both in front of me right now... Apple's iPhone and Samsung Edge... one has the microSD port and the other doesn't.
Honda could redesign the EFI computer with a simple add on slot and make it so it reads that for it's map.
I've seen people actually do this for Ford's EFI.
I can see the argument holding a bit better for something like a shock, but even then it's doesn't fully hold water. Building crap takes energy, building quality also takes energy.
Quality doesn't alway cost more energy to make.
