I take good care of my bike always check everything once a week..Could it be my chain that is to tight? I got a around 22000 km on it. Ow and my Icon jacket starts flapping on 200+ like crazy (almost chokes me lol) and yes im completely tucked in like a midget
I agree, your bike is fine.
I doubt you're chain is the issue, esepcially if you're maintaining it.
The drag your jacket is creating could be slowing you down a bit.
You might want to buy an aftermarket double-bubble windscreen. Even in full tuck, the oem screen doesn't provide much coverage/aero.
Also, are you shifting above 12k rpm? If you're short shifting, it'll take you longer to get to top speed.
But something you can't change, like sl66ICEcuba mentioned is, you're not a small guy. You have considerably more surface area to create drag.
That all being said, 240ish kph is pretty close to max speed on a stock rr. I beleive max speed on a stock rr is 160 mph, which is 257 kph.
IMO I call BS on anybody that says they can go a legit 280 kph/174 mph on a stock rr. It would take serious modification to get to that speed, way more than an exhaust/air filter/pc combo.
