You can not speak for others. I am fully aware of the popularity of aftermarket upgrades with "people."
I guess I should have been more specific. Could you give us any specific examples of where YOU have experienced (purchase & used) an aftermarket part that performs better or is better quality than those made by Honda?
Let's face it, everyone is different in size, height, weight, arm/leg length, etc. If ANY Honda motorcycle product came off the line perfect, it would have to be, one size fits all! It doesn't work that way!
I for one didn't even like the ST1300 when it first came out, BECAUSE IT DIDN'T FIT ME!
Even before putting the first mile on it, I had to add a riser, fatter hand grips (stock cause my hands to cramp up!) and a throttle lock (my hands go numb).
Then I rode the bike up to NorCal for a ride on the stock saddle! Oh what a mistake that was. Thank goodness I had already ordered my first RDL!
Then I found that my boots were marring up the step where the foot pegs were, so I had to put on some boot guards.
I hit the horn it goes off with a very weak Road Runner sound, had to replace that with a Stebel. But to get the Stebel to work, I had to run wires from the battery to the front to handle the wattage!
At least in Europe, Honda knew it didn't do enough for comfort, so they had the option of the topcase, where as here in the States, we had to pay big time to get one!
Mirrors are too flat, had to add spot mirrors.
Throttle tubes are weak at best, had to replace with a G2 ThrottleTamer for smother action.
The helmet locks are a joke! You have to open up the saddles to get to them? Not one of their better ideas!
The windshield is too narrow at the top, I prefer the V-Stream myself!
Along with a few other things I've added for my OWN COMFORT that Honda didn't bother with!
So Yeah, a bike that comes off the line is not ready made for EVERYBODY! Many have to MODIFY them to fit right!
