Cracked carbon front frame member

[DBRK]

I hit a tree on the right side a arms and kinked the tunnel a little bit. I built a reinfocement plate and got it straightened out and was putting it back together when I noticed this. Front carbon frame member is cracked right where there is a hole in it for one of those plastic christmas tree rivets.

It looks like I can't just replaced the one tube. Have to buy a whole new front frame assembly. Will the alumium frame out of a standard RMK fit right in? Does it come with the mounting brackets for the coils?

Any help is much appreciated!

Seen lots of Carbon ones for sale on eBay all the time.

Yes, I have done this. the standard rmk frame bolts right up. Has all correct holes and mounts for misc attachments.

I've replaced all my CF front structure tubes with thin walled Titanium tubing.

I have replacement Titanium, CF, as well as some stock aluminum tubes I have removed and replaced with my Titanium tube if you want to replace the tube. PM me if you are interested.

Brent,

Do you have any photos of your Ti setup... sounds good.

What kind of weight comparison to the stock aluminum structure?

Injected adhesive?

The aluminum overstructure can be had for about $160 (street price)... as said above is a direct replacement.

Yes and Yes,

Poor pic quality but here is one.

I left what Polaris claims is "CF" for the cross tube as it sees little stress and don't think the plastic coil mounts would survive the heat needed to break the bond.

I'll Jig up a few more in my spare time and pre-drill them. If you want one sooner I have three done if you want me to send you one and you send your core.

The Ti tubes are 1/4 # heavier than the CF but while I have the tube out of the way I lighten the lugs. So essentially the TI tubed structure is the same net weight as the CF one. Additionally no chance of complete failure as the TI will bend / kink if you put too much force on it, but that much force will also bend the stock Aluminum tube and I have never heard of that happening.

If our dollar ever recovers I'll be getting this.

Not tearing it apart now. It can wait till summer at this point. I have the aluminum.
