fork swap
I do not know any easy fits for the forks on an 1125. But their are 3 ways that Ive seen it done.
1. you are a machinist and have mills and lathes and you don't need me to tell you anything!
2. Get donor forks and rims and brakes, etc. Then have a company make you a set of custom triple trees to fit those forks to your 1125 (or whatever bike).. probably cost $500-$900 for the custom tree.
3. There are some pre made kits or parts out there to do the swap... for instance I am putting 1125r forks on my X1. Someone makes a stem that I can use on the 1125r forks to allow them to swap directly into the X1 frame. Usually requires bearing changes in the neck...... this type of swap generally requires a bit of research to find the right bits.
