RE: Kinda Porky - flynrider - 03-30-2014 Compared to the bikes that it mimicks, I think the CB11 weighs just about what I'd expect it to weigh. A standard, double downtube, steel framed bike sporting a liter sized inline 4 has historically weighed in the low 500 lb. range. I say historically because there aren't any modern bikes with that configuration. But if you look at the UJM liter bikes of the past, they're right in that ballpark. I don't think modern bikes with smaller lighter aluminum frames, monoshock suspensions, plastic fenders and the like are directly comparable.

My point is that it would be better still if it was lighter by about 50 pounds. The physics is simple - it would accelerate faster, stop quicker and go around corners quicker if it were lighter. It is simply a matter of cost benefit - it costs a lot more to make a lighter bike and the CB1100 is pretty inexpensive - quite a good deal actually. Obviously steel is both cheaper and heavier than aluminum, magnesium, titanium, plastic and carbon fiber.Yep. What's funny about all this is cars are similar. I just got a 2014 Malibu 2.0 Turbo which makes 259 HP and 295 lbs/ft of torque. That's similar to the Mustang of the mid-60s with the 289 HiPo V8, but the Mustang weighed 1000 lbs less. The ~2L turbocharged engine has taken the place of the baby V8's across the board and has a hell of a lot of performance, but a half-ton more weight? That weight all went to a much stronger chassis and safety features, infotainment systems, computer systems, and so on. But what's very interesting is that the Malibu is a much faster car despite its weight "disadvantage". The Mustang's top speed is maybe 120 mph for anyone nuts enough to try it; Malibu 2.0T is a measured 155 mph. 0-60, Mustang, is 8.3 seconds, where the Malibu can do it in 6.1 seconds (Malibu specs are from Car and Driver's road test). It's in the efficiencies, there is far less friction loss in modern engines with modern oils, the design is more efficient, the car is drastically more aerodynamic, and the six-speed automatic transmission is a huge help. Another interesting point is that the Malibu is actually faster than the Impala, a car that makes 305 HP and weighs only 100 pounds more, but can barely get up to a measly 149 mph because of the additional drag of the larger frame. Quarter-mile and 0-60 times are identical. So all that additional power is still not sufficient to go "faster". Gas mileage is better on the Malibu, too, so I guess one can sometimes have cake and eat it, too. The CB1100 may LOOK like a retro bike but as I demonstrated to myself this afternoon, the engine still revs like a modern motorcycle and I ride it like I would a modern 600cc sportbike, mostly in the upper third of the tach. It loves it. Might be heavier than some bikes but it's pretty efficient overall. Less weight is always a good thing and I was about to post something similar but didnt earlier. As a bit of car fanatic myself the first real decent attempt at weight reduction seems to be the 2015 Ford F150. Its a cost/benefit issue with everybody but they know what they have to do. Cars/trucks have gotten entirely too heavy and that goes for them all. Motorcycles are no different. Maybe we will see some break throughs in the future.

Obviously steel is both cheaper and heavier than aluminum, magnesium, titanium, plastic and carbon fiber. I would agree in concept that lighter is better. I also agree with your most recent post that it would be tough to make this bike lighter without raising costs significantly. Fortunately, the bike's design makes it a fun, flickable ride notwithstanding the weight. RE: Kinda Porky - thessler3_imp - 03-30-2014 I agree with your comments. It is a nice bike to ride and I was impressed during my short test ride.

I'm trying to think of a motorcycle (or any vehicle) that wouldn't be better if it were lighter by 50 pounds. No luck so far.

Granted, I'm used to handling big, heavy bikes, but the CB doesn't feel at all heavy to me, either in terms of handling or just lifting it on/off the side or center stands (in fact, if I didn't know, I'd guess it was actually lighter than the ZRX1100 I own--it certainly turns in quicker). It still accelerates fast enough, even stock, to embarrass all but the quickest sports cars. I doubt the extra pounds on the '14 deluxe will change that very much. You should write for a magazine. Perfect recap. Everybody's different. I rode a 2014 KTM 1190 cc. not sure what the model is called. Weight probably around 400 to 450, not sure. The bike will go 0 to 60 in 2.9 seconds, and 0 to 100 in under 6 seconds, and top out at about 155. Fun to ride for about 30 minutes. I love my CB1100. Want a lighter faster bike, they are out there to purchase.

I'm trying to think of a motorcycle (or any vehicle) that wouldn't be better if it were lighter by 50 pounds. No luck so far. That brings us to road bicycles. At some point they get quite unstable at speed if the wheels are too light. If the setup is right a 17-lb. bicycle can be very stable even at "high" cornering speeds, with good tires, at the right pressure, and the right wheels. That combo is no less magic than with a motorcycle and it's very hard to find. Do it right and you feel almost like you could drag your knee on the bicycle; do it wrong and it's white knuckle. I personally feel that one example of a bike that is 50 pounds too light is the FZ-09. Yamaha just went too far with the light weight on that one. Wheelies real easy, though.
