Guide To Measuring A Motorcycle Wheel Offset

I am often asked by customers "How do I measure my motorcycle wheel offset before stripping it"? 

So hopefully this section can guide anyone with the same question.

Step 1; Remove the tyre and inner tube, Step 2; Remove the brake shoe plate or disc rotor. Step 3; Find a good straight edge like a steel rule or good quality spirit level etc. Step 4; Lay the straight edge across the outer edge of the brake drum or disc brake face of the hub make sure to avoid the bearing housing as this can be a different height (Fig 3).

Step 5; Now measure the gap between the underside of the straight edge and the outer edge of the wheel rim, do this in at least 3 different area's around the rim to get a true average and this is your offset.

In Fig 1 you can see a wheel with two positive offsets so A & B measurements will both be as described above BUT in some circumstances you might have a negative offset as in Fig 2 so this should be noted as minus number i.e. -10mm for instance, this measurement can be obtained by laying your straight edge across both wheel rim outer edges and measuring between the underside of the straight edge and a point on the hub.

Note;

If you are bringing me a complete wheel to strip and rebuild I will take all the offset measurements so you don't need to.
