I have a pair of the f-kingdom 911's. We have only had the left swingarm break on one. This was due to a combination of the chain going tight and the left foot peg mount being slightly misaligned putting stress on that side. Secondly the bike that did it is running a bizeta 6-port and sava A's, through a flat out left hander. We found out later when stripping it down that one of the bolts going into the swingarm brace had sheared off, causing the whole assembly to flex.
Other than that, both bikes have been great, with no other cracking even after several very large crashes. If you can get hold of the f-kingdom models they are a great bike.

with the standard engine they are pretty slow, but all the Genuine polini bits bolt straight on, plus most bizeta bits.
The fuel caps are crap, just buy a genuine one. Chassis and handling wise they are great. Frames are only cheap if you do manage to break one.
a crap chassis with a fast motor is still a slow bike. Try and get a ride of a few bikes, and buy the one that handles best and then worry about the motor. It is far harder to make a chassis "faster", motors are easy.

I've had 4 blata reps now, 3 were just standard reps, 1 is a blata SQ. I've found the SQ blata rep to be the best bike i've had yet.
I have spare frames of both the wavey circle designed frame and the normal type.
The only issues i have with the blata is the waterpump, as wbr mentioned you won't know when it breaks. But they do last quite a while so you shouldn't have a problem.
I haven't used a polini rep, but i'd prefer a slower bike with a stronger frame.
The peg mounts on the blata are quite weak but they are cheap and relatively easy to changeover.
One other thing with the blata was the frame not always lining up, so at times you might have to "ENCOURAGE" the frame to sit right while you put the bolts, but once its together they are perfect.
i have a polini rep and a blata rep sq, and the polini rep when modified poos all over the blata rep.
the polini rep just handles soo much better.
blata reps are still nice bikes and are great for what they cost, but if you can get a secondhand modded polini rep, i would do that, as thats what i did and im extremely happy with it
