Top speed for the XT?
 
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..

Well, I don't recall ever exceeding an indicated 95mph on mine and I don't intend trying to push the speed envelope any further either! ;)

119mph with no luggage, tucked in, slight downhill.

Not even tickling 6,500 RPM... ran out of road before I could find out if it went any faster.

I have had my XTR with standard gearing 15/45 up to
170kmh passing a line of cars...

Kev 07-09-13 23:35
I have been over 200kph on Chris's big bore 76hp XTX sitting up.

Indicated 177 kph on my XTX with standard gearing, flat down on tank with 2km straight run up. If you wanna performance bike look elsewhere!!!!

Im not looking for a performance bike, I just had a question why I only reach 167 km/h when others can reach 187 km/h .. That is 20 km/h more, quite alot..

Maybe it is because of My weight... :p 98 kg.. ;)

Just a thought... You haven't got/had a Speedo-Healer fitted by a previous owner? Your top speed sounds about right if you assume the speedo is spot on and accurate. XT speedos tend to read about 10% fast. So 187kph on an optimistic speedo is going to be about the same as a 167kph on a "corrected one". In which case you're bike's speed is roughly the same as everyone else's! ;)

Check it with a GPS...

Yes, will check with gps..
Don't think a speedo healer is installed. It was also default kitted with 15/45, so no speedo healer was needed.. I don't think the drive line has ever been replaced. Only 10500 km (~6524 miles?) on the meter when I bought it.
