I have seen people on youtube ride their bikes in approx 187km/h (~116 mph). How fast can you drive with your bike?
I have not got my bike faster than 167 km/h (103.7 mph).. Well, I don't remember the weather conditions and I'm quite heavy (~98 kg, ~216 lbs) but how can the difference be so big?

I have open air filter (K&N), slipon, Kev O2 controller and a PowerJet to get more fuel.. I have default sprockets (15/45) as well.. Is it only possible to reach 187 km/h with other sprockets or do any reach those speeds with default sprockets?

Isn't my bike well "burned in" when it was new or why don't I reach higher speeds? It feels very responsive even in those speeds..
