RE: Z900RS Dyno run
2013 CB 1100 tested by Rider Mag and Jett Dyno

On the Jett Tuning dyno, the CB1100 made a healthy peak of about 85 horsepower at 7,300 rpm (the 1969 CB750 was good for about 67 at the crank), and roughly 67 lb-ft of torque at 6,700 rpm at the rear wheel, 90 percent of which is available from 3,300-7,000 rpm.
Fuel Capacity: 3.9 gals., last 0.9 gal. warning indicator on
MPG: 86 PON min. (low/avg/high) 38.6/40.3/42.7
Estimated Range: 157 miles
Indicated RPM at 60 MPH: 3,250

Right; some dynos consistently give lower numbers, some higher.

Their real use is to track changes after doing some kind of engine work.

There was a shop that Sport Rider always used that seemed to have really consistent numbers. A lot of the real "accuracy" comes from the dyno operator's ability to properly correct for temperature, pressure, and relative humidity. Not all dynos, nor operators, are created equal.

Most likely you would end up with a 79.5 HP CB1100 from that dyno; errors are usually always in the same direction.

That Jett Dyno is actually the dyno at Jett Tuning in Camarillo, CA. http://www.jetttuning.com/

I think maybe Ferret said that. I get confused sometimes Smile

If you come to a fork in the road, take it!

You just go ahead and wash your mouth out with soap, young man!

Actually, to be fair, I've noticed that Rider Magazine's dyno readings usually tend to be on the high side, compared to what most people in California see from their own bikes.

The one thing I haven't seen as much of lately is the so-called Magazine Ringer bike, which we used to see all the time during the halcyon '90s and early 2000s, back when the market for sportbikes was so strong that the development/new model replacement cycle for the 600s was down to two years. Back then, magazines always seemed to receive blueprinted, dyno-friendly special bikes that none of us mere mortals could ever hope to purchase from our local dealers.

Thankfully, magazine test bikes these days more accurately reflect what we see from dealership bikes.

Stopped by a dealer today, sat on the bike, nice ergonomics...but all the numbers aside, I just couldn't deal with that radiator...looks like I opened up the hood of the car:

İmage

Although it's in the same position, I don't notice the CB1100 oil cooler much--smaller and doesn't have that cap sticking out.

CB also doesn't have that clutch cable draped so sloppily across the right side of the motor, or that beached whale of a gas tank. And the CB's fins aren't fake.

While I like the overall package of the Z900RS, there is something funky about the shape of the tank, especially when viewed from the front. It looks like a tortoise shell or some kind of hat and not an integrated part of the design.

I hope there are enough purists out there to encourage Honda to continue building a reasonably authentic bike.

However, I am concerned that they may return to carburetor from the tone and content of some of the comments.

That said, I rode my Wolf Classic 150 about 20 miles around town, hill, and dale, doing an errand. Took the long way.

Single cylinder, REAL cooling fins, and REAL kick starter, and a carburetor.. That thing truly holds its own in urban traffic; top speed is 65 mph+, and it is tempting to consider hopping onto the sidewalk.

It's about as simple as it gets. Regular gas, 85 mpg.

Maybe Honda could just add a kick starter to the '18 model?

RE: Z900RS Dyno run
While a fake kick starter might sound ridiculous to most of us, I'm not sure that I'd be all that surprised to see a manufacturer some day add such a thing to a retro styled motorcycle and market it a "kick-assist starting system". (You'd still have to thumb the starter switch of course, lol.) I could see some guys pulling off the fake kick start effect before riding off in front of a crowd of people who don't know any better. This would probably sell to the same people that find the fake carbs and fake cooling fins to be appealing.

Lol, it's been done for the movies, for sure!

But the CB1100 has an hydraulic clutch, so the options for routing the cables are myriad.

It actually runs under the tank and is a pain in the buttocks to change. I replaced mine with a custom length from Galfer when I did the CB500 bars. Had to remove the tank and a few other odds and ends.

The Kawasaki routes the cable that way to get the smoothest, most friction-free pull.

I can tell you that on my CB1100, the throttle cables were not properly routed, and even after I repositioned them (when I checked the valve clearance) there was still a bit of binding at full lock. It's a tight squeeze under the tank.
