Horsepower is like crack, once you have some you always want more. I keep eyeing the ZH2, they raised the price this year so I am most likely out, but what if?
I don't disagree with you at all. More HP just usually means less throttle adjustment is all.My experience is quite the opposite. Horsepower is about acceleration at speed. On interstates, it's just not that important. You'll get to your target speed eventually, maybe slower on some bikes than others, but plenty fast enough. There's seldom a need to accelerate briskly on interstates. You're just cruising. All you need is a vehicle that can maintain an appropriate speed, with some to spare.
The place where horsepower to weight ratio (which is what we really should be talking about) really matters to me is when I'm passing a dawdler on 2 lane roads. "Enough" for me is whatever it takes to make a brisk, authoritative pass with no drama, in whatever space my sight line safely affords -- which in mountainous areas, may not be much -- without spending more time in the oncoming lane than absolutely necessary.
For that, my Wee is more than adequate; its acceleration is plenty authoritative when it needs to be, and definitely faster than most 4 wheelers. Any more would unnecessary to me. If I ever pulled a wheelie, I'm quite sure I would sh*t my pants.
That's just me. There are as many answers as there are people here.
Oh that opens a whole memory hole, right there. There was a consensus that a batch of K75s had a deformed transmission bell housing (for those that don't know, they had a driveline much like a car, with a dry clutch even), either from a shipping accident, or manufacturing error. This means you could replace parts until the end of time, but the misalignment would eventually wreck the splines again. Frequent "spline lubes" were the solution for many, but what a PITA that was! Typical BMW would never acknowledge the issue, of course. Whole cottage industries popped up to remedy quirks like these, including remanufactured input shafts with splines that weren't too short!I owned one of the bricks ('91 K75S), and lordy, did it ever have driveline issues. I rode it for 18000 miles (from around 72k to 90k or so, and when I finally parted it out, I calculated that it had cost me over US$.80 per mile to ride (counting fuel and all consumables, as well as endless repairs). Insane. I didn't know the backstory. Maybe if I'd ridden it gently...?
My Vespa LX150 has, I think, 12 HPSeems like there is natural assumption of owning just one bike. Which is everyone's paradigm until they decide to get a second, third, or fourth bike, etc. But what happens then is you find out your favorite power to weight ratio is for different activities. Grab your sport touring beast for a ride in the mountains. Grab your Norton Commando for short back road rides, vintage events, or meet up for dinner. Pull out the dual sport for ride to the grocery store or camping.
I need a bigger garage.
Horsepower isn't measured it's calculated from torque that is measured.We get so focused on the motorcycle's peak hp and we use that number as the indicator of the bike's power, but we usually overlook the horsepower throughout the full rpm range because it's hard to put a number on a power curve. The important horsepower number which we should be concerned about, is in the rpm range which we operate the motorcycle. Peak hp at banshee rpm is meaningless if the engine is never operated at that rpm. Dyno graphs are semi-informative but do not always show the full picture because the dyno runs are created with a wide open throttle.
And why I absolutely love my Norton Commando. No motorcycle is more pleasant to me than that bike between just above idle and 4,500 rpm. Of course you can't actually see anything at idle. You eye balls are bouncing around inside your skull way too much to focus, and above 5K rpm the bikes shows it's age a little bit, but that sweat spot is heaven.but we usually overlook the horsepower throughout the full rpm range because it's hard to put a number on a power curve.
I am a ME and am in full understanding of the hp calculation of torque & rpm.Horsepower isn't measured it's calculated from torque that is measured.
A power curve showing torque is a better indication of how the motor is to ride.
