Great, thanks for your info. I look forward to hearing about the setup...I'm a "little" heavier than you are, so perhaps they'll be looking OK as you have them...
When you say that the fork travel is less, is that due to the spring stiffness? The springs aren't coil bound at all?
The R6 forks should work very well once I have them sorted out...that bike is a fair way off that stage yet...I chose them because I wanted fully adjustable and stronger/stiffer forks...may need to go to gold valves etc. on these as well in the end.
Please keep us informed on you setup.

I think the limited fork travel is down to spring stiffness rather than being coilbound. They are long springs and progressive rate, I think they are 0.40 - 0.70kg so almost double the stiffness of the stock forks when compressed.
I think the R6 forks should be awesome and if you have the front wheel and brake setup as well.... shame they're not legal for Forgotten Era....

Hi.
I have the calipers and mastercylinder, but I have fitted a new wire wheel to the front with a twin disc Talon hub. I have now decided to go back to a single 340mm custom-offset floating disc...not sure what calipers to use now...perhaps a 6 piston???
I wonder what the R6 calipers would be like on a single disc? Tempting to try and see...on;y problem is that I have to make an adaptor to place any caliper I fit further out to the side (and out to accept the larger disc)...I don;t really want to make heaps of these...
Single discs look lighter and probably work very well....twin R6 type discs on the SR might even end up a little too severe.
I now need to get a decent rear disc hub as well....when

....I get around to it..I hate hitting send buttons prematurely!
I have fitted custom triple clamps with the same offset as an SR. This is to allow fork to tank clearance for the alloy tank I've had made...
I'm going to get a swing arm made that is a little longer and use longer shocks....to steepen the fork angle...also fitting a decent steering damper as well...

All sounds good! I would go single disc rather than twin disc. The SR is not quick enough to need twin discs and the additional unsprung weight would cause suspension problems. It's bad enough getting them to handle without adding to it! I'm only using a single disc with an old Brembo twin pot caliper and it seems to haul up nicely. Could always do with a little more braking power for racing but SRs are all about corner speed, rather than desperate braking manoeuvres. ;D I finally got the bike out on the track yesterday and had a lot of setting up to do to get the handling right. It was like a pogo stick to begin with and I almost ended up on my ear! Tankslapper with pogoing on the way into Corporate Hill, very interesting.... So the forks demanded my immediate attention! I started with 20W oil in the forks and this gave a rather sluggish rebound action, so I went ended up with 10W oil and around 3.5 turns of preload on the gold valve emulator to increase compression damping. It seems increasing the compression damping also has a side effect of increasing rebound damping so I think it is important to get the correct weight of oil to get the right compression to rebound damping ratio.. Once the front end was sorted, the rear end showed the same type of behaviour even on max damping, so I will need to get the oil changed in the Ikons to a thicker grade. I will know the results at the next track day or race meet... Oran Park Sep 9 hopefully  |

Here's a curly one. When I took the shocks off the bike, the right hand shock fell apart  The rod had somehow detached from inside the shock body. This explains the lack of damping and why I didn't feel it earlier on in the day. Imagine what would have happened if it was a monoshock... There's something going for a twin shock setup after all  The shocks have gone back to Ikon for replacement. I will still up the weight of the oil to leave room for more adjustment when the weather gets warmer. |

Ooops,
Not so good!
There used to be problems with some of the Koni's in racing years ago...something to do with the failure of a plastic bit inside the shocks...can't recall the details now.
I've never had any worries with them though...I've got three pairs...two old type (...steel and alloy bodies) and the adjustable 'modern' ones on the Honda racer.
One benefit of having IKON situated in Albury is that you have a easy direct line to the factory.
Keep the info coming, it's certainly interesting...
