You are right and no, I would not buy a Bandit. In comparing the Ninja 1000 & GSX-S1000F, be aware of what you get & don't get.
The Suzuki GSX-S100F doesn't have:
⦁ An adjustable windshield
⦁ More fairings
⦁ Power modes
⦁ Drilled & petal brake rotors
⦁ Integrated front turn lights
⦁ Chassis sensors
⦁ Eco mode
Kawasaki has:
1. Kawasaki Traction Control System (KTRC) - it works better than the Hayabusa's
2. Kawasaki Intelligent anti-lock Brake System (KIBS)
3. Power Mode
4. Kawasaki Corner Management Function (KCMF)
5. Bosch IMU, with chassis sensors
The Suzuki can't be better because it doesn't have all of that. Yeah, sure, Suzuki has TCS alright but guess what, Kawasaki's works better. They are not the same. Suzuki doesn't have power modes and they haven't applied chassis sensors to the bike yet. So, that tells you, the level, that Kawasaki is at right now, with their Ninja 1000. The overall package is much, much bigger. As usual, that also proves, how stripped out the Suzuki GSX-S1000 really is. The Bandit is the same way.
Suzuki didn't match the rotors to their calipers either. Suzuki's tires are also less sporty. The engine is also smaller & so is the fuel tank (4.4-4.5 g). The mirrors are on the handlebars. What it does have is, a little more high rpm power and it's lighter, which makes it feel more sporty. That's absolutely it though. It isn't a better tourer, hwy or high speed bike. In the 60-80 mph roll, the GSXS won by .1 but in the 80-100 mph roll, they tied. Highway passing rolls for both are fast and I mean real fast. Faster & as fast, as a Hayabusa & ZX-14R, depending on year.
Weight
Weight is a debate. The 2014 Ninja 1000's wet weight is 509 lbs., while the GSX-S1000F is at 475 lbs. That's a 34 lbs. difference. Where is all that weight though? At 1043cc, the N1K's engine is bigger, that's 15-16 lbs. Fuel tank capacity, for the N1K, is 5.0 g, compared to only 4.4-4.5 g. That's 4-5 lbs. right there. Now, the Ninja Z1000 weighs 475 lbs., compared to the N1K's 509 lbs. A reduction in fairings equals 15-25 lbs. So, the Ninja 1000 has about 15-25 lbs. worth of aerodynamics on the body. That's the weight difference. See, the Ninja Z1000 & GSX-S1000 weigh the same & so does the N1K & GSXSF. There isn't a shortfall. It isn't, that the Ninja 1000 is built flagrantly heavy, it just has more of everything. You get more, with the Ninja. The Bandit though, is half made. Let Suzuki put, everything in the bike first. Me, I wouldn't go that route.
