No trap door...there is a hump mod for storage though....I'd have to use the search feature to find it...so I leave that up to you...others have done the hump mod as well where you cut it out to keep the grab bar on.Ok, I reluctantly have to ask. What other must have accessories do i need? :-) Is there an accessory to make a trap-door in the aerodynamic hump directly behind the seat. Maybe there is a DIY thread on this, but I couldn't find it.
If people change out the mirrors and GSXR1000 mirrors seem to work well, I think mine are from an '09 Gixxer.
Some put the GSXR front fender on (I personally like the Hayabusa front fender).
I have a throttle rest on mine which works pretty good in giving the hand a rest...
