Im not positive but im pretty sure it wont just directly bolt up. Most likely you will have to do some frame modifications, or they might make a kit...

no it wont just bolt up...your gonna have to do some hefty mods to get that bad boy to fit. it can be done, but its not an easy job by any means.

Its not an easy thing to do. Here are a few things you have to do:
1. Move top engine mounts forward.
2. Move bottom mounts forward.
3. Fabricate radiator mounts.
4. Fabricate new oil tank.
5. Modify right footpeg. (clearance for kikstart)
6. Modify swingarm to fit in engine.
