Aussie 1150gs Rally hybrid

Here are the first pics of my project. After seeing what Jim Rowley had done to his R1100gs and looking at the BMW dakar & HPN bikes, I thought I'd give it a go myself.

I bought a '99 BMW 1150GS that has been smashed, the motor was dead with smashed cases and the bike was in 10 boxes, but the price was right.
Add another motor, Yamaha YZ450 front end, Suzuki DR650 'Safari' 32L tank and a KTM 660 rally fairing and this is what you get...

Here is another pic taken after my first test ride. The test ride went great except that the fuel line split and sprayed fuel all over my leg and onto the motor and exhaust!!!

Thumb Nice

that is totally sick.
Where can i get one?
Seriously man, how does it go o/r with the new front end? It's a bit like the HP2 never made in the 1150, with an adv tank!

The new front end is GREAT! All I added was 0.52kg fork springs to the standard '05 YZ450 forks. Off road it soaks up any bumps, rocks rock ledges with ease. It feels so much more like a dirt bike. If I don't look down at the heads I could swear i'm riding a "normal" dirt bike.

In the front end conversion I added a "back bone" that is welded to the front subframe and bolted to the rear sub frame, like the HP2. This "back bone also supports the tank.

Sean. That`s a great looking bike, what did you have to do to get the tank to fit and more importantly, to work?

After looking at photos of every big tank I could find, I thought the DR650 Safari Would be close to fitting straight up. It had to clear the heads, so it couldn't come down too low (like the KTM 640 Adv) and also had to clear the alternator. I looked at a few DR650's with the standard tank and it looked good. So without ever seeing on I ordered a Safari tank and crossed my fingers...

The tank arrived and I placed it on the bike... Perfect! I bought some Suzuki DR650 rubber tank mounts and hung a bracket off the "back bone" just like the factory Suzuki DR650.

I've got the build photo's but they are on my work computer, I'll post them this week.

The rake/trail is still the same. Just with USD forks. I was given a few tips from Jim Rowley on the rake/trail (thanks Jim).

The bike WAS an ABS model, Just unpluged and then cut the computer conector off!

I used to run Heinrich tanks on my airheads back in the 70s and 80s and want a bigger tank for my 1100GS, but they are so bloody expensive. This looks like a cost effective answer.

That bike looks fantastic! Where did you get the fairing?? Is it a stock KTM part? Is it aftermarket? I'd love to get one like that...

The fairing is a fiberglass copy of a KTM 660 Rally fairing, I think '99. I got it from a bike shop in the Northern Teritory, Racers edge (I think) they made a mould of them and now sell the fiberglass copy. About $200 AUD

Aussie

I have always been impressed by Aussie ingenuity. The stuff that comes out of there is nothing short of incredible. There must be something in the beer or something! Really good job, well done Man!
