Hi guys,

The other day I did put new HP progressive springs on my XTR. However during the test ride at speed above 120 km/h I experience weaving of front (steering bar). After I adjusted the rear spring preload to max the problem seems to have improved a bit but still there. And I am not a heavy bloke wright 80 kg plus never had this problem before.
My first thought was to buy rear hyperpro spring and change it, which I will but still wandering.

Any ideas?

Thanks.
