Just wondering if anyone has had this problem with the 450r I bought it new in oct of 05, it has been raced flattrack only, called the dealer yesterday, they looked at it and said Honda would stand behind it, I have the extended warranty, they also said they have seen a few do that so it must be common, probably should gusset the new frame before they start changing things over to it.

 

Haven't seen any cracked yet. How many times has it been wrecked, what mods(suspension) are on it, and where did it crack at?

 

I have rolled it twice, easy rolls though, lets keep in mind I am 36 years old and I am not going to do anything to crazy, stock shocks, +2 JD performance a-arms and dura blue eliminator axle and the hrc kit, ac nerf bars that is all I have done to it, the cracks are starting in back of the top motor mount or in front of where the top sub frame is bolted on it looks like a cast piece welded in and it is right behind the weld, on both sides, dont get me wrong I love this thing wouldn't get rid of it for anything

 

Can you point out for us just exactly where the crack is?????

First off, this frame doesn't have a reputation for cracking (you are the first post I can recall), but any racer would be wise to gusset it anyway.

 

I tied to explaim where the crack is in my first post I know it is a little hard to understand, I also have talked to 2 different people in the last 3 days and they have seen this problem, keeping in mind one of them is an A class rider in motocross, I understand that is expected from that situation, the second was in a bad wreck, understand that one to, I also called the Honda warranty number in my warranty book talked with a Honda tech. out in Calif. they said the new frame will be a different design which tells me that they have seen some failures, if it ain't broke don't fix it, I tried to post some pic.of the crack but it tells me that my pic. is to big? How do I fix that?Thanks
