fitted rear pillion pad and carrier back on C5 in the hope the doc's will let me go abroad,tried running the bike with screen+tank bag ,without screen but with tank bag then naked (the bike not me) all at around 65-70 to try and find why it;s wobbling like a scary jelly but to no avail gonna try tyre pressures in morn as think reccomended pressures in manual way too low especially the front(18psi) can't see what else it could be as bike is only 4 month old and I haven't altered any components, still love riding the thing though,Don
