i think everythings been said that needs to be. they do go nice i was tempted to put my dreambike motor in there and continue using it, but i dont like the brake setup at all and what not.
mine was an SQ - its stamped into the trees and motor
the frame -

had to drill out the hole on the motor mount end and reweld the back end to get the tyre to sit right, it was on a pretty savage angle. maybe this one was just a one off. but none the less.
do you run ultimate micro superbikes? i think it may have come from there. was almost 3 years ago i got it now though cant remember.
its a shame the proper GP3 frame ones arent so easy to come by, id love to convert one with a BZM motor. would be a very competitive bike. but yeah. i guess my sentiments would be i wish the bikes didnt need a big old cash injection to get them competitive. cause they have a lot going for them.
BTW wbr out of curiousity is there anything much needed to get the polini in there? just flip the brakes and wheel over and it all lines up or new spacers needed? guess youd need to fabricate a top end mount as well.
