Wade, you should be nicer to the next front end. Good luck with the rebuild.

I haven't seen too much about it, but I did see 1100cc

Ain't you got anything better to do than taunt me with yet another unaffordable Bimota - and this one is (sadly) pure vaporware.

Bimota DBX-1100

I was waiting for a thread like this.

I got a 2005 Ducati ST3 that had been in a garage fire for really cheap.

This year, I decided to do a build like yours for the DirtBag Challenge. I got all the suspension work done, but couldn't make it run due to EFI CPU issues... it's one of the red key/black key models. I'll replace it with a MicroSquirt.

Anyway, looking forward to your build.

I'd like to see what you've got done so far - parts choices, etc. For the EFI issues - have you heard of DucatiDiag? An inexpensive enthusiast written full-access bit of software:

Don't know if it would help you out - if you've got the red/black keys, this will let you read/erase error codes and completely reprogram your EFI. Also supposed to let you recalibrate your speedo, remove O2 sensors and turn off immobilizer/remove stock instruments.

Thanks for the link - I'm pretty interested in trying out the MicroSquirt, but I may try the diagnostic before pulling the trigger on the MS. Both the red and black keys have had some heat damage, which may have ruined the RFID chip.

I got a CRF 450 roller cheap. Swapping the steering head was dead easy: turned up some cups for the bearings, and a 3/8" thick spacer between the top triple and the steering head. Bolted up like a champ. A better and easier, but more costly solution would have been to buy tapered roller bearings in the correct size.

The rear was quite a bit more work.... and I have a penchant for understatement.

I started with the ST3 swingarm and removed all the stock shock mounting hardware, leaving only the main cross brace. I then sectioned it aft of the cross brace and added 2.5" to accomodate a DR650 wheel with an 18" rim laced to it. I chose the DR rim because it has factory cush drive.

I then sectioned the SA in front of the cross brace and added 1.25" there in order to accomodate the shock and linkage from the CRF.

I did all this cutting and welding basically as a one-time-use for the DBC -- I have plans to create a new SA from scratch using 3" x 1" tubing. There is a ***big*** problem with adding travel to the ST3 SA: the SA pivot pinch bolt interferes with the sprocket. The pinch bolt will have to be changed.

The lower shock linkage mount required a bit of tinkering, too. I plan to make a removable cradle which will have an outboard bearing for the swingarm, footpeg/shifter/brake mounts, and possibly split dirt-bike style radiator mounts. The doohickey with the zig-zag is a removable frame section. I've made 2 so far, and need 4.

Here's a photo gallery of the progress to date:

Thanks for that. I didn't want to hijack the OP's thread.

I finally got my butt in the shop and peeled back some wiring harness to get the old frame free - also had to pull the injector set:


Can you tell which frame is which?


Now, I need to put the "new" frame and wiring harness back on - and start mounting the front forks.

[Ted.audia]

fantastic progress and glad you are back working in the shop! Keep us posted on how things are going

I need to take inspiration from you on my own monster conversion/money pit

cheers

How much trouble is it in NM to change the frame? titled as a different bike? or changed numbers on registration?

What are ya doin' with the old frame? I have yet another project looming and could use some bits off it

I was patient/lucky enough to get a frame with title, so it's just another bike to the DMV.

What devious plans ya got for a bent Duc frame? Or maybe it's "what bits?"
