DL650 fork swap with a Multistrada??

Just want to throw this out there for discussion:

I have a DL650 with a fork brace, springs, Race Tech emulators and 10w oil. I like the setup a lot, and its a great improvement over stock But I read that the Traxxion Dynamics cartridge upgrade is the ultimate in adjustability and performace for the v-strom front end. That system installed is about $1,300

So here is the question, would it be worth the time and money to try to fit a Ducati Multistrada 1000 or 1100 front end to the DL650?

The first question is could it be done within $100 (or so) of the cost Traxxion kit?
(I think this is possible using used parts on ebay, etc)
Second, would the improvement in performance and adjustability be the same or better than the Traxxion kit? (this includes the potential improvement from the 4-pot calipers on the Ducati forks and hopefully a stiffer overall system)

Note: I know the RaceTech emulators and oil weight have very good adjustability, but I like to make some fine tune adjustments on the road for both road conditions and load conditions.

Here is the setup I would envision to be optimal:

2004-2006 Multistrada 1000DS front end: (the Showa forks, unless I can find some Ohlins units for less than $1000, but I believe they have 1" less travel)
-Forks (compression, rebound and preload externally adjustable)
-Triples w/bar mounts
-Calipers

I would love to use the following from the DL650:
-Wheel with brake rotors
-Speedo/odo drive
-Axle (with shims to fit the Multistrada forks)

In theory, the geometry of the bike should be pretty close to stock with the option to lower the forks in the triples but probably not raise them.

I know this is a lot to digest and most likely more work than its worth. But I was not able to find much information to see if these parts could even be made to work together...so I was hoping folks here could provide some thoughts.

Here are things I have considered:

Fitting the triples:
- pressing the DL650 stem into the Ducati triples or
- using the entire Ductati triple setup (I dont know the size of the bearings on either bike, or the length of each stem)
- DL650 fork center to center spacing is about 8", any ideas what the Ducati is?

Fork Length:
- the Showa forks are about 32" total length and about 31" from the center of the axle hole to the top of the cap (can anyone confirm?)
- the DL650 forks are about 31-32" from the center of the axle to the top cap
- The Showa forks have 6.5" of travel, Is the DL650 about the same?
- the stock Showa spring rate is 0.76 kg/mm so they will be on the soft side (this can be fixed of course)

Front Wheel:
- DL650 has the keyed spaces for the speedo/odo drive, I would imagine the bottom of the Showa forks could be modified to hold it in place
- the DL650 has 310mm rotors, the Ducati has 320mm rotors. Would the 10mm difference make mounting the Ducati calipers unsafe or not practical?
- wheel hub width and width of brake rotors
- the Showa forks have the 4-pot calipers

Im sure there are many factors I am forgetting and many more questions that this type of thinking will create. But I hope it will be something to discuss.

DL650 fork swap with a Multistrada??

And wheels,remember the Multi has a 17" front wheel.If you use the Wee wheel you will need to machine spacers etc and new mounts for the calipers.It's all the " Little " things that will getcha !!.

Even if you do an Ohlins swap, you would be better off rebuilding your current front suspenders to suit your riding style and size. The MS is designed for speeds much higher than the wee is designed for, nor will ever see, thus the need for better suspenders. And any mod you do to the front will require an upgrade to the rear, or you will have an unbalanced and unadjustable suspension.

If I had the remains of an MTS , which miraculously had an undamaged front end, I'd consider it - otherwise, it's going to be a LOT of work for dubious returns.

RMZ front end now ....

Thanks for the feedback thus far unk:

I have considered the width of each wheel and the fact that using the DL wheel will require spacers. I also assume the calipers will require some type of bracket or offset to meet the discs on the DL wheel since the 17" rim on the Ducati most likely has a wider hub area.

I have the Elka 4-way shock in the rear, so any change to the front should be balanced out by the shock performance and adjustability.

I am not looking for a setup that is doing fork springs, emulators and oil (I have that already installed on my DL), I am looking for something to match or beat the Traxxion kit for adjustability, damping, etc.

If I had a Ducati front end laying around or had access to one this would be a lot easier to determine the level of work involved. That's why I asked if anyone had a Multistrada or had access to one to take some quick measurements.

This is not a project I plan to undertake in the near future or ever, but thought it would be good food for thought since there are very little DL650 fork swap info out there (which probably says a lot about the upgrades most do to the forks: they are more than adequate at that point)

Triple clamp offset is really important.
I'd be very surprised if the stock Duc front end worked as well as the full zoot Traxxion setup

It's too bad that there are few options for our forks. I've been searching for billet clamps to replace the spindly crap that we have butlocated none. Suzuki could do better.

I'd still suggest MX forks

Realistically, DR 650 tubes fit and intiminators will likely be fairly good, a couple of inches more travel, excellent damping ?

Yeah, MX forks would be a huge improvement over the stock Wee. I don't see where any MX forks will even remotely fit as those are much larger in diameter with 3-bolt pinch triple clamps, single front brake disc systems, no fender mounts except under the lower clamp, front-end height relative to the frame geometry....etc. But, with how good MX suspension is , Id like to see an adaptation for the Wee/Vee.

I agree that the MX forks are a very good idea. I believe there is a thread either here or on ADV where someone used KTM forks and made it work well with raising in the rear to even out the bike to get it close to stock. He used the front wheel and dual disc setup as well.

Since DR650 forks are damping rod (like the Wee), they dont have external adjustability and the only benefit would be longer travel, but you could get that with MX forks, so why not go with the MX option, right.

I was really looking for a set of forks that would almost match the stock Wee/Vee travel, be cartridge forks, and have external rebound, compression and maybe even preload as well. But there is no way to really tell what will work without getting a set of triples and forks and playing with it. Which is something that i dont have the time or money to do, but its fun to talk about.
