when you change the tail section on a f1 to a f4 or f4i tail, do you have to change the subframe in order to suport a rider?

 

the stock subframe can be utilized, but you will have to add additional brackets to support the pillion end of the tail fairing if you want it to be load bearing.

 

i guess that is on how you do it. i would not recommend messing with the subframe really, with enough fabrication you can make it work without doing all that. the rider support isnt the tricky part, its the passenger support that would take some work to get right.

 

yeah I was wondering about the passenger really, I guess I worded it wrong.
