    I have a 82 Seca 650 and am very new to motorcycling. At any speed if I let go with one hand my front end shakes badly. What could this be

    Misaligned front or rear wheel, bad front tire, unbalanced front wheel, bad springs in the forks, no oil in the forks, even a badly warped brake disc could do it.

    Or...

    Having lived through the ownership of a Vmax (known for their weave and wobble issues) I understand the problem can bee a little elusive.

    In general speed wobbles come from one of three sources:

    Wheel/Tire - Roundness problems. Balance problems. Tread irregularity.
    Inflation issues. Intermittent drag from brake (warped rotor)

    Steering - Bearings (worn, overtightened). Bent triple trees. Top tree twisted slightly.

    Forks - Low/uneven oil. Worn bushings (lower bushings in particular). Worn fork lowers. Bent/worn tubes.

    If the wobble can be induced at any speed it is not likely to be the tire.
    If it happens at a specific speed each time it is almost surely coming from the wheel/tire.

    The simplest place to check is the front wheel. It is easy to have it checked or balanced (high speed instead of static).
