My R100 GS is back on the road after having spent the last ten years on my R1150GS Adventure.
The one and only thing I miss is better lighting. My GS Adventure also has a TerraNova light bar and a pair of Hella FF50 driving lights.
With a limiting 280W alternator (and I'm not looking to upgrade that component) on the R100 GS, efficient lights will be a factor.
Any ideas and photos of your set-up would be appreciated.
