I am completely redoing my 1988 Africa Twin RD03 at the moment and have put off deciding what to do with my rear shock until now. The original Showa shock needs replacing/rebuilding as it has vey little damping (needs reecharging) left and I believe the spring to be a bit tired. My biggest priority is reliability and rebuildability. Ideally whatever replacement should be able to endure a RTW. I realize that at some point during this RTW the shock is going to need an overhaul, or replacement. The idea is to go with whatever solution gives me the best reliability. Secondary is race-spec performance. I want to explore what options are available and recommended with price being the last priority. With many of the original AT components being of above average quality, is rebuilding the original Showa on option I should consider based on reliability? Should I instead go for a modern supension which undoubtedly be more performant, yet perhaps less reliable? If so, which? Thanks in advance!
