110 70 17 front tyre

Excuse me my fried but  I've sold the rims. But remember that the bearings of the YZF is 28 mm thickness and FZS 20mm. So I made adapters with external diameter 28 and 20 hole like that of the photo.
The model is 2000 YZF 1000 THUNDERACE

I think I have found bearings that would fit without the need of adapters:

Thunderace: 25 (inner)x52 (outer) x15 (thickness)
Fazer: 20x47x14
Conversion: 20x52x15 -This measurement is easy to find, so putting that rim would be an easy job (If I am not wrong)

By the way the YZF750R fits the same rim.
