are the front forks on the 9 a 56mm???
ok thank you so much zoomYes and no.
The tubes themselves are 46mm KYB cartridge units, but the outer housing is much larger. And it's different at different points. I measured mine with digital calipers when I was thinking about making a set of tube covers, and this is what I came up with.
At the upper triple clamp: 57mm
Between the upper and lower clamp: 55.5mm
At the lower triple clamp: 58.5mm
Between the lower triple clamp and fork bottom: 57.9mm
At the very bottom of the fork: 64.2mm
If you're looking for clamps that fit around them, pick the area you want to clamp to and get something that fits in that range. Most clamps for lights and such would need a 56mm or 57mm clamp.
