i'm thinking about changing my f4i & get a 07rr but i'm worried about the subframe it looks like it's soft like paper is there any one making a deferent subframe or is the sick innovation sub cage good enough also can a fI 12 bar fit i like to do alot of bar trick i'm kinda old school also how do i dent that tank? tell me every thing i need to know about that bike some pics would help thanks

 

completely need a different subframe to do bar tricks and dont drop them hard the engine mount will bend thats with the fi cage of course

 

Its a 05 but almost the same bike

 

i sold my 636 to stunt an 07rr for a bit. it was ok but i ended up getting another 636.

 

so how did the subframe hold up?
