The TAG positioning for the sake of comparison

r1100 swingarm with r100 shock

Please get us a photo of the other side.!
To see how they mount the r100gs shock on the R1100 swingarm.

Or even better if they have one on a bench, to see the welding and if it is internally reinforced.

Really interested in this mod..

Interesting thread

I have....scratch that, had the HPN Paris Dakar model with a 13mm offset on the rear wheel and have never come across any unusual behavior. I use the bike for a lot of very slow technical riding in skills challenges and I would reckon that it will have a more severe influence riding slow and turning in steep. I have never noticed that I need to compensate between left and right turns. At speed the bike is as stable as can be on both dirt and tar.
That said these long chassis bikes are dogs to handle in slow technical stuff. Getting over obstacles is a breeze but tight turns is a nightmare and requires lots of practice and knowing how to place ones weight. Even then most skills courses have many tight turns, to small for this bike to turn in. With the HPN I can't compete even though I might be more skilled than most. It is a lot of fun though and I always give it my best.
On the other hand I have been riding many a sand track at speed fully loaded with luggage and plenty fuel and this bike is in its element.









In this sand riding video the rider with the helmet cam is also riding another HPN Paris Dakar model. You'll see my bike later in the clip doing a few light tumbles as the track starts to get tight and windy and me out of energy.

Looking back at it we did spent a bunch of time discussing wheel offsets on this thread.

Now that I am up and running, I also cant feel any effect on handling from this

Just saw this post, so I'm probably too late, but just in case I'm not...

Would you mind measuring the drive shaft length ? I'm building a frame with a 1150 swingarm, and I need to shorten the 1100 drive shaft. I was going to go trial and error, but if you have got that drive shaft handy, I would be much obliged...




And while you're at it, what length of torque arm are you using ?

Baie Dankie en Vriendelike Groete.
