They all do the same job.I put on the hepco & Becker in 2002 when I got the 1150 new. Main reasons is coz I liked the look. My brother had some on his r850r. Ive never had problems taking rocker covers off and if doing an alternator belt on the 11xx,I just take the middle nut and bolt out and pull the bars slightly out and the cover drops out easily(providing the allen screws are undone). If you dont fancy eng bars,streptoe does some nice headguards. Really depends on what you like the look of on your particular bike.Have a look at the pictures of different bikes with different bars/headguards on this site and just go with what you like the look of.You may get others sayin this is better than that and that is better than this but like I say they all do the same job.
