Thanks Monkey - In my defence I did say I had no idea. Just assumed they would be different due to different swingarms. Notice no baiting re. which swinger is better - after my battering due to my less than kind critique of a certain MotoGP rider, I'm lying low for a bit .

Mick - I'll let you know if I decide to sell the SP item. .

RE. Which one to keep...I'm trying to contact Maxton for some advice on their shock which is currently fitted. It would be nice to try both out but I am not sure about how to swap them over and I only have a rear paddock stand. Presumably the bike will drop like a sack of spuds when shock is removed. Will search this site for advice on changing shock, then might swap 'em over so I can make a comparison.
