Welcome...The bike is restricted in the US market due to emission laws.
The exact same bike bar possible additions like immobiliser, different coloured wires in the loom and thankfully the omission of those ridiculous BMX style side reflectors, is sold in EU, Australia and other world territories.
So in effect, the bike the US gets is not neutered due to any mechanical limitations.
A performance motorcycle that revs up to 15000 revs and produces 200 BHP from a 1 litre motor is a precision instrument much like a high quality swiss watch.
This motor is reliable enough to complete the Isle Of Mann TT race where it is at max revs for (3 x 37.73 miles), which is 113 miles, at near 200 MPH speed(superstock bikes I'm talking about) for nearly 17 minutes. Imagine putting your bike on a dyno and holding it at near redline RPMs for 17 minutes.
As you can imagine, this engine is more than capable for what we mere mortals throw at it.
The one thing that precision instruments require is sticking rigidly to scheduled maintenance, and the single absolute that a precision engine requires is fresh oil changed at or above the service interval.
