Beim Bremsen aus Geschwindigkeiten über ca. 70 km/h hüpft das Vorderrad erheblich.
Reifen, Bremsen, Stoßdämpfer sowie Lenkkopflager sind in Ordnung. Könnte es am Schwingenlager liegen bzw. wie kann man das Schwingenlager überprüfen oder gibt es noch andere Ursachen? Wer weiss Rat??

"When braking from rates over approx. 70 kmh the front wheel hops. Tires, brakes, shock absorbers as well as steering head are correct. Could it be because of the swingarm?"
I would make these tests:
1. Revolve the front wheel and apply the brake gradually. If the brake shoes do not grab evenly as the wheel is revolved, perhaps the drum is warped. This may be caused by uneven spoke tension.
2. See if the steering bearings need to be tightened - the manual says to pull the front fender forwards and backwards to test for free play.
3. Remove the front wheel and put it on a wheel stand. Check that the wheel is both true and balanced.
4. While the wheel is off, also remove the front shock aborbers, and see of the swing arm moves up and down smoothly but with no looseness.
