I would like to lift my 2003 Rockster a bit, and someone can offer me 2nd hand parts from a R1100S which has been raised both front and rear.
I want to buy the parts (front fork and short rear cardan stabilizer), but am not sure if they will fit...
Does anyone know, or have experience with donor R1100S stuff? (especially front fork).
As mentioned, the Paralever strut from GS is simple. That piece was used on the R1100S Boxer Cup bikes to raise the bike - and cylinders - for better leaning ground clearance.
Rear ride height is also determined by the rear shock length.
For the front, I'm not sure what R1100S Telelever forks will do... the Rockster uses the same parts IIRC. Seems to me that the front end ride height for a Telelever bike is foremost a function of the front shock/spring length, though I suppose someone could hack at the fork tube lowers and extend the length from lower Telelever ball joint to front wheel axle centerline... but why in the world go to such expense?!

What Mark said - the Rockster uses the same front as the R1100S already (in a different colour), and to raise the rear, just get a GS Paralever strut.
You could try fitting a GS shock too - don't know exactly what that would do for the UJs though, it might be too much. I don't know how different the position of the upper fitting for the rear shock is between the GS and the R/Rockster.
I had the original shocks and GS paralever torque arm which raised the bike in the back. I then had Ohlins built for the Rockster, the front and back are height adjustable, and after having them installed and set, I had to replace the GS torque arm back to the OEM (the center stand was not long enough to hold the bike.) With the new shocks, the bike sits higher in the back and a scant lower in the front. The ride is more aggressive and the bike handles like never before. The shocks were ordered and installed by Mitch (mitchsmotorcycles.com) and custom built by Fast Bike Industries (fastbikeindustries.com).

All; thx for the advice!
my purpose was to raise the bike in order to make it look better, but especially to increase the handling.
I think I start with the GS torque arm (can buy on any corner), but on long terms I think I will need the ohlins
(or comparable) as suggested.
Also: raising the front will probably not increase the handling...
If you raise the bike, hopefully the same amount front and rear, say for looks, the basic handling will be affected negatively as you have raised the CG as well.
Replacing the stock (385 mm long) torque arm with that of the GS (365 mm long) will reaise the back end of the bike ~ 1/2" which in turn will shift a bit of weight to the front and improve the turn in....this is one of the most common upgrades for those that want to improve the turn in.
