Im not exactly sure about compressed shock height, but the seat pan on my bike is flat across from where you made your cuts on the frame. The rear hoop rakes up 15* and the seat pan remains flat with the bend of the frame.
I have scraped the tire on the seat pan once or twice, but only when hitting hard bumps on the highway. Rear tire is 18x3.5 and I have the preload set to the 2nd hardest setting.
I weigh about 160lbs and have ridden passengers, so theres been some weight on the back and I havent scraped from that..
Thanks. So your seat pan sits on top of the frame, right?
I probably have 2 inches more clearance in that area. The spot I worry about 2 inches past my frame cuts there is 0.080 inch aluminum sheet to mount the tail light that's more or less vertical. It's just above the frame rails. That's the first thing the tire can hit on extreme travel. Best I can figure is measuring on the arc established by the swing arm I have about 3.5 inches clearance. I'm thinking if there's a way to add some stops or cushions at the end of travel it might be a good idea.
