My attempt to fit was while waiting on new wheel bearings, so my wheels were off the bike. I attempted to see if a Yamaha R1 rear tire hugger would work somehow.
I discovered the following for the R1 tire hugger:
1. Will not work on lowered bike w/ oem fender still installed.
2. Will require brackets to be made to make up the minimal gapping between the hugger mounts and the swingarm. This is necessary to prevent the hugger from rubbing on the battery box.
3. If you're a good fabricator, you could shave a portion of the battery box and plastic weld in a curved section on the bottom rear corner to allow for the movement of the hugger on with the swingarm.
4. OEM fender removal WILL be required with the squared hugger. The flat face does not "hug" the tire like the rounded one will.
5. OEM fender removal might not be required with the rounded hugger. It rides closer to the tire throughout.
6. A swingarm mounted "fender" will require bracket fabrication, possible rear brake line relocation (due to front mounting area), battery box may impede swingarm movement (due to front mounting area unless you fabricate around that issue), a side mount plate bracket and rear signal alternatives may be needed (up/down movement easily causes wires to break, use grommets and wire loom if you run them through the swingarm).
Let me take you there and back again.
