Front fork interchangeability Gen1 -> Gen2?

[Viktor L]

Posted the same question on the Gen2-board but I though I'd increase my chances by posting here as well. Just wondering if it's possible to do a direct swap between the older model and the newer?

Currently I have a 2006 model front fork on my project bike (an old GSX1100) but I'm looking at upgrading to a set of newer Ohlins forks with radial calipers meant for the Gen2 Hayabusa.

The older fork has the following dimensions:

Upper triple: 50mm
Lower triple: 56mm
Wheel spindle: 32mm

Anyone got an idea if the newer Gen2 forks have the same dimensions? Spacing between the discs and such isn't really an issue at this point. When that times I can sort it out either with custom made discs (got connections for that) or some spacers.

Putting my faith in you guys. lease:

Cheers.

Not a direct answer to your question but might give you an idea

I was more curious about the fork legs themselves rather than the springs inside them. Internals can often change between years in order to improve the handling, but the outside can stay the same.

Thanks though.

Any other clues? :confused2:

I found some info now.

The forks have the same outside diameters, the only difference is the wheel spindle. 32mm on the right fork leg, 25mm on the left.

Thanks for your time anyway.
