Bike is a KTM Super Adventure still under warranty with active suspension and OEM Conti Trail attack 2 tires.
Front rim has been balanced and trued on a digital machine. No side to side wobble but there's a vertical oscillation between 40-60km/h more pronounced on smooth Tarmac. Bike feels like it's on rough road or even a similar feeling to lugging in a higher gear (it's not lugging though). Feeling goes away after 60 and is pretty smooth. I have a warranty recall in on the front rebound cartridge of the bike which is going to be replaced, however some other owners report the same effect even after cartridge replacement.
Any idea what this might be due to? Current owner theories are:
Bad OEM tires (although it seems some owners have the same effect on after markets)
Bad OEM rims. Seems a rim can still have defects after balancing and truing. Is this correct?
Road reading suspension software error. This is my current theory but I can't exactly back it up with hard facts. Just my gut feeling as the oscillation doesn't vary in frequency and is only present at a narrow speed range.
Im going to have the shop look at everything again but would just like some of your expert input before I do.
this is more of a niggle rather than anything else but this did happen in a corner recently and the bike felt pretty unplanted as you can imagine.
