Funny thing, I just bought one for my bike. Nice subframe and excellent customer service if you have any questions or problems. MSRP is about $435 for the '00, or you could buy three AC's. Moto Sports Outlet has them a bit cheaper, but Mike at AC would probably match their price.
I ahve neard only one good thing about AC from 727.
You can get a BBR if you ahve a good relationship with a dealer through White Brothers for about 240.
Or, you can go on to ebay and wait for one to show up:confused: .
Well, I need to explain a bit more. Did some research on the AC's. A friend bought an AC for his 2000 KX. It looks great and everything fit perfectly. I have a '98 and I had just received my AC but hadn't installed it when I posted the last message. The sub-frame is made of larger diameter AL than the stock. The '98 is round tubing vs. the square on the '99 and up.
My sub-frame mounted up perfectly, but the plastic didn't fit perfectly and one of the threaded inserts came out.
Contacted Mike at AC and he took the frame back without question, fixed the threads and double checked the alignment. Had the sub-frame back in two days. The plastic is still a little off, but not as bad.
The answer to the alignment differences between my friends and mine was this: The round tube frames have to be heat treated and they sometimes warp. The square tube frames don't need the heat treating, so there is no chance for warping after they are welded.
In any case, the mis-alignment on the left number plate was slight and AC indicated no reservations in taking the frame back if I wasn't satisfied. Mike even said I could try if for a while, and if I was unhappy, he would refund my money in full.
Since you need a newer square tube sub-frame, I would recommend you give it a try. You'll save quite a bit of money and the frames do appear to be of quality construction.
That said, if you need a round tube frame, you may want to consider another source. If I do have any more trouble, I'll probably be contacting BBR to see what they offer for my bike.
Funny you posted that. I just checked out BBR after posting my message and found that deal. I couldn't get my wallet and phone fast enough. I ordered two. Can't beat $100 for a BBR sub-frame. I'll mount it up tomorrow and probably send the AC back.
Bought an AC sub-frame for my '99 KX250. Quality and workmanship seemed to be high. No problems with fit or finish. I did buff and polish it out before installing it. Plastic and alignment were spot on. The above thread that listed some problems seemed easily remedied with a call to AC. I would buy from them again. Especially since at the time the dealer price at the local money pit... er shop was $300.00 plus.
Yes, mine was square. I was not familiar with the process for the round vs. square and heat treating and all, but seems to make sense.
I rode the bike for another year with the AC sub-frame, no problems. Never bent it, the thread inserts never stripped or pulled out and I was very happy with my purchase. Now if BBR had one of theirs for $100 buck at the time, you can bet your "sub-frame" I would have been all over it.
