So sadly the RF suspension and frame stuff was not "budget" but it wasn't like a gsxr. 96+ 900 got upgraded forks but the "hot ticket" was just throwing racetech goldvalves in them. Worked much better.

So despite the looks the frames on those bikes were steel. The engine is the same oil boiler found on the gsxr and bandits. Well the bottom end of the 600/900 is the 1100 case from the gsxr1100/bandit1200. Why? i don't know. I think the rf400 was based on the early 91/92 gsxr 600case/bandit 600 case. So the pivot diameter and how it fits is likely very similar to that found on "slingshot" gsxrs. Might be a good place to look for what arms people put on those 2nd gen GSXR builds for an idea. I ran a 95 arm on my kaw so i know the arms from 88-96 were interchangable but got bracing in the later years. 96+ SRAD gsxrs i believe also fit but the "dog bone" linkage mount went from the top of the arm from 95 to the bottom of the arm in 96. The RF bikes had the linkage mount on top like the slingshot gsxrs(which also makes me think those arms likely swap).

Are you trying to upgrade for looks or some performance?

also quick google search.

part way through the bike got a gsxr subframe and tail and a USD front but updates stopped in 2014.
