spondonturbo Posted February 20, 2016 Share Posted February 20, 2016 Hope you can help. I am looking for an extended swingarm for my 1100 WP. Are the WP swingarms different in pivot width and shock set up to the earlier oil cooled models? I have seen ones for oil cooled models for sale, but want to make sure they will fit and I have a feeling they are different? any advice please Quote Link to comment
Jaydee Posted February 20, 2016 Share Posted February 20, 2016 I've done it the other way round, put w/c arms in slingshot frames. Don't forget the w/c stuff has a bigger diameter pivot bolt than oil cooled. This may be a problem, but you might get away with some sleeves/top hat spacers on the w/c frame so the oil cooled pivot bolt can be used with its respective arm. Quote Link to comment

Jaydee Posted February 20, 2016 Share Posted February 20, 2016 (edited) It's a good while back since I last did one. I put one of the later 1100w braced arms (after banana arms) in an 1127K. From memory the arms pivot widths were the same, just the W's arms use a fatter pivot bolt. It was just a case of glueing the 1127K bushing/sleeve in to the water cooled sleeve so I could use the slimmer slingshot pivot bolts. I used the W dogbones (slimmer than 1127 so clears shock and inside of brace ) and used the slingshot knuckle with them. Don't forget though, you're working the other way around so have to sleeve the two sides of the frame as w bolt wont fit through an oil cooled arm.

Gammaboy Posted February 20, 2016 Share Posted February 20, 2016 (edited) Wn & Wp bolt is the same size as oil cooled, WR is bigger Edited February 21, 2016 by Gammaboy 1 Quote Link to comment

I did try a banana arm in my K (fitted the slingy frame no problem) before the braced arm but didn't like the look but it was that long ago I couldn't remember the pivot bolt size so assumed it was the same as the later braced arm I used.

Ahh fuck, wrote that the wrong way round, WN AND WP is the same size as oil cooled (20mm I think), WR (the braced one) is bigger, 24mm I seem to recall. Was chasing my 2 1/2 y/o around a playground while trying to write that earlier post. Quote Link to comment
Gammaboy Posted February 21, 2016 Share Posted February 21, 2016 (edited) Oh, and SRAD/Busa/K series GSXR will bolt in with linkage swaps (and the bushing as per a WR swinger swap) , all are longer than W series 750 swingers from memory, K6 onwards are longer than W1100 I think, K8 onwards are really fucking long. (I researched the shit out of swingarm swaps for my aborted WP project) Edited February 21, 2016 by Gammaboy 1 Quote Link to comment

When it comes to water cooled model, I'm happy enough to just know the early ones are bananas and the later ones are braced. It's not like an important subject such as oil cooled. 2 Quote Link to comment
spondonturbo Posted February 21, 2016 Author Share Posted February 21, 2016 (edited) all good info lads. Currently have a busa arm in the bike so that makes sense with above. Looking for a nicer arm like spondon, jmc etc. So SRAD, Busa or k series only will go in but with a linkage swap, but L/M/N or WR will not - have I got that right? Its for this Edited February 21, 2016 by spondonturbo photo add Quote Link to comment
Gammaboy Posted February 21, 2016 Share Posted February 21, 2016 L/M/N will fit. If you've got a busa arm in it, it means you've already done the spacer in a spacer trick for the bearings, but still have a 20mm axle - so L/M/N, WN/WP will fit, WR/SRAD/BUSA/Kseries/Lseries will fit with the spacer in a spacer job. 1 Quote Link to comment
spondonturbo Posted February 21, 2016 Author Share Posted February 21, 2016 thanks Gammaboy. I didn't put the arm in but will assume the last owner did the spacer bit. I am going to take it out and see what has been done and go from there. Cheers for the help Quote Link to comment
