Thanks for that. Somehow I knew the Harley guy would find a way to insult anyone questioning Harley's reliability. Anyway, thanks for the
unbiased info.
So the answer to my question is that these people that I had talked to either owned older models, or were just making things up. Does anyone know if any specific Harley model/year is less reliable? Any model/year to avoid?
Telesque, you are correct. Gearing is the indicator of engine speed in relation to speed, but what would the max speed an engine is capable of mean? Also, could driving an engine capable of 90 max at 70-75 most of the time or for extended periods reduce the engine's life? Would I be pushing the engine to its limits? These are not Harley questions anymore, just mechanics...I am curious to know...
The simplest way to answer that is basically that you're working with speed vs. acceleration.
You can tune an engine to have a high top speed, or you can tune an engine to pull a lot of weight. If you've ever played around with gear settings on a racing video game, this is a pretty good way to learn.
By reducing the amount of power an engine has to spend on a high gear (i.e. High speed) you increase the amount of power it has to accelerate. You also increase the amount of weight which the bike is able to move. It's sort of a balance in there, but that's the idea.
Now, in addition to this, larger engines produce more torque, but because of how engines work, generally have less horsepower (because of low RPM ranges). This makes them very useful for drag racing (accel.), but less useful for, say, Formula/Gran Prix racing (speed). That's both why heavy bikes, like cruisers, have larger engines, and also why cruisers aren't ashamed about weighing a lot more than sport bikes.
