Came across this interesting idea in a Visordown review of the ZRX1100/1200 back in 2008: If you're used to sportsbikes, then by comparison the ZRX is a heavy and slow-steering beast, but an easy and worthwhile handling mod is to rotate the eccentric chain adjusters by 180 degrees. The result is around 20mm extra rear ride height, making the steering usefully quicker. I'm interested to know if anyone already tried this and if so what is the feedback?

Have not done that myself, but am aware that some who have done it that have found that while the slow speed quickening is good, they have also encountered some additional high speed "twitchiness". Some like it in spite of the high speed issues. Be aware that it raises the seat to ground distance a bit as well. Easy mod and easy to return to stock if you don't like it.  |

Yep tried this a while back, it did quicken up the steering which was quiet pleasent but i wasn't happy with how the bike sat on the stand afterwards it seemed to be almost on tippy toes (as you would expect with the backend raised), it wasn't a major issue but i had images of it sinking into the tarmac and going over, i also managed to gouge my swingarm with the chain (probably caused by pot holes on our crap roads round here) so i ended up flipping it back to standard, you can also raise the forks threw the yolks 5mm which has the same effect tho with lowered ground clearance.
As Lighty said, try it and see how you get on, easily put back again if you don't like it mate.

OK sounds like a great fix but there's more to it than you might think, yes rotating the rear axle 180% will lift the rear with the said effect BUT this is not the hole story as the possistion of the axle in relation to the center of the front sprocket is very important as under excelleration the chain is tight on top off the sprocket with all the weight going to the rear of the bike, the bike should squat hard down, but this is not the case the bike dose sit back but due to tyre size over sprocket size the rear in real terms is rising, now flip the rear axle below the center line of your front sprocket & under excelleration the geometry now try's to pull the swing arm up along with weight moving to the rear the bike doesn't handle well wheneing shot hard off a corner, Oh & the same applies under brakeing, I could go into it in great depth but trying to keep the nuts & bolts of how it works simple.
If you want the bike to steer a bit quicker simply drop you forks through the yokes by 10/20mm.

Thank you for the great feedback guys, much appreciated. In response, I think I will leave my eccentric chain adjusters as standard.
I certainly don't want to damage my swing arm, make the bike twitchy at high speeds, alter the allignment of the sprockets or axle geometry with detrimental effects
