us 'mericans dont know KMPH but i take mine to 100 mph dirt and pavement............it is squirlie on groved pavement even at 65 and it will wag a bit on the dirt especially if its got many tracks and soft but it has never been anything that was scary
always on knobs mostly m-12 on the front and whatever on the back 17 lbs both tires. they are balanced and have rim locks
forks are on the first line from the top and i usually have a safari tank and full or empty dont seem to matter.
is your front axle square? rear tire aligned? sag set properly?
sorry man out of ideas
