R1100GS HP1 Conversion on the cheap!
 
I've always wanted to mess around with one of these and do this conversion. I have seen a few front frames in the forums here and none of them looked very stout so I thought I would just build one myself.

I am using a 48mm WP front end from an '03 Husaberg. I got an extra left hand fork bottom and slider on ebay and I will have to machine some kind of offset bracket to carry the calipers. The two sides will need to be different (as opposed to mirrored) due to both of the fork bottoms being the same. I looked at it briefly with the wheel and rotors put together and it looks like it should work. I'll be using the nissin 4 pot radials from a gsxr or something-- I can't remember at the moment.

Here are some pictures of very early progress:

Here is the front subframe with the little jig I made for holding the headstock in the correct location while I was fitting up the tubes.

Here is a picture with the rear wheel. I had a 5" Excel built up by Buchanan's with a 170/60 17 pilot power on it-- I can't wait to take some rubber off this thing.

here it is with the completely ridiculous looking 41 litre Touratech tank.

I read your other post, http://www.advrider.com/forums/showthread.php?t=409691

anyway, is possible to get one like this already done?

Most conversions have been done for off-road purposes. Is this a road-only conversion? I ask because I prefer the stock set up for road and conversion for off-road.

Excellent work BTW.

Some people are FAR too talented....very jealous! Looks like it will be really cool:clap

Did you need to arch the frame to clear something specific? Just wondering what led you to that particular geometry.

Edit: I'm guessing it's to clear the lower triple clamp at full lock...

Crafty......
 
If you've got the skills! and I expect a kit could be developed for older GS's.....keep posting......Bruce

I may develop this a bit further and offer a kit with just the frame-- you find your own forks and everything else.
I'll keep posting and we'll see how this one turns out first.. I know it's way overbuilt to begin with, but the first one always is.

Thanks!

This will be an off-road conversion eventually. I just wanted to start it out as a giant supermotard and see how it handles and then put a different front wheel on it. I plan to take it to China in the late spring this year so I will have some on/off-road tires and a slightly larger front wheel (19").
