bandit 400 / gs425 suspension swap

[mrbridgeport]

Hi Guys,

Looking in to doing a modern setup on our AHRMA GS425 Superbike Lightweight for this race season. From what we've heard on our end is that the front end and swingarm from a bandit 400 should bolt up w/o too much trouble to a GS425. Has anyone done a modern swap on a GS400/425? Any help would be appreciated .

Did you ever get any further with this? I, too, and another member have been wondering if there is any longer/wider swingarm that will be an easy swap into the GS400/425/450 frames.

Looks like SR500/TT500 aftermarket swingarms can be used in XS650's, which I determined to install a GS1100E swingarm into an XS650, an inch or so needs to be removed from the width at the pivot. I believe this is a similar difference with the GS twin frames. a GS500 swingarm can have twin shock mounts welded to it and is much longer and more rigid, but still steel, but a good upgrade nonetheless. Still slightly wider.

The RF900R aluminum monoshock swingarm is the same width as the Bandit400, and probably GS500. the B4 is a steel arm. The RF may be a good ticket to mod but looks to need narrowed slightly as well, maybe 3/16" off each side approximately.
