If its any help I have just fitted a 6mm spacer and bar risers with preload from JAWS great service from him by the way, what a nice bloke, The spacer took less than 20 mins the risers took a bit longer coz I dont read instructions that well (rung John up he took the piss and it was all sorted 10 mins later). The bird now feels so much better the front tracks perfectly where it always felt a bit iffy before and the bar position suites me much better and has taken a lot of weight off my wrists. maybe its just me coz I have been used to quick steering and 32 inch wide bars for my fun but I think it was a few quid well worth spending.

Weigh 12.5 stone, run Givi top box some times!

Added 5.5mm spacer on rear shock and backed of pre load by 2mm slightly increasing sag!

Currently play with ZZR11, another Inj Bird, CBR600F, 955 Tri, ZX12, ZZR600 and K1200s..........still waiting for one of them to pass me!

NOT always the bike.............Rider and Bike combination that counts! I find the Bird VERY easy to ride fast....LOTS of bikes are quicker, but the Bird is EASY to hussle along......bit like pony from local stable V race horse.................we know which is best but only the best can extract it..meanwhile normal pleb's are better suited to std stuff with lots of room to forgive!

It's great you guys all say fit a spacer, but I've not seen anything mentioned about setting the sag after this was done?

I only fitted a 2.5mm spacer, just to try and I must say - It did make the bird better on the track, slightly quicker turning feeling.

But doing 260 KPH - GPS speed on a right sweeper had my arse wobbling all over.

That's no fun at all. Had to fight the bike and drop a knee to try and keep it on the road. Only afterwards did I start looking into static and loaded sag, and found that this was completely off.

So basically, don't just think that by putting in a 6mm spacer that everything is now going to be better - it ain't! Check the front and rear sag, and set it up according to the info provided.

I'm still not 100% happy with mine, still fiddling with the suspension, and have dropped the spacer out to try and get my confidence back after that scare.

A little confussed - Whats fitting a spacer got to do with static sag? back end of bike still weighs the same before and after so sag would remain the same? Difference is with the sterring geometry?

I did back off the pre-load on my bike purley because rear end was too hard as std! this effectivley alters the sag which actually bought the height of the back end back to std whilst maintaining the sharper steering.

Therefore I physically increased the sag following fitting of spacer and altered the front geometry because of the effect on the chassis from the introduction of the spacer. If your bike is going like a po-o stick I would suggest that your rear shocker is either past it's prime of you have set it too soft allowing the torque / grip to over power it's damping inducing said condition (very much a past trend for Honda M/Cycles).
