Everything works fine, it accelerates OK from low revs and the engine pushes hard...but when 260-265 km/h has been reached, it doesn't go beyond, and (as confirmed by all of you) more than 20 km/h are missing.
I'm quite sure that this is beacuse of the factory engine map or any other electronic limit... hope it can be switched it into B mode
First thing to do is go to a 15t front sprocket give that a try and you will probably find it will give you more top speed, the engine struggles on the standard gearing due to it being to tall, easy to do before you spend any money on garage bills. The type of day and humidity along with temperature will also affect the engine performance, i don't think there is anything wrong with your bike at all, give the sprocket a go:biggrin
