I have a 99 SRAD front end. I am running Pilot Powers in a 120/60/17 and 160/160/17.
The SRAD front end is a bit shorter than stock SV. I have the upper flush with the top of the fork tubes. I was wondering if a 120/70 would help restore more to the stock geometry. I know the difference between the two sizes, just not sure in my applicaiton.

The tire feels fine, but I have less than 200 miles on the tires.

just run whatever you have currently. if it feels comfortably, keep usin the same size. if it doesn't, try the 70. doesn't hurt to experiment.

FWIW, i have a 70 front

I am going to run the 60 until it is shot, but was curious about ride height. I guess i should get the lenght of the SV and the length of the SRAD so I can have the actaul numbers. This way I can fugure out what is what

The GSXR front end is 19 mm shorter than the stock front end. A 70 front tire will be 12 mm taller than a 60. So if you run a 70 on a GSXR front end, the front will be 7 mm lower than the stock SV front end.

If that 7 mm is still too much for you, you can have a Race Tech 10 mm travel extender installed in the fork which will bring the front end height up to 3 mm above stock. You can send you fork to SV Race Shop and they can install the extender, revalve it for the SV, and install new bushings for about $200.

I put a 120/70 on mine at the same time as I did the swap, and I run the GSXR tubes flush with the top of the yokes- with the SV parts I had a 10mm drop. So I suppose I'm actually taller at the front than I had it before.

this might sound weird, but I do not notice any problems with the shorter front end and 120/60.
I was just wondering if I would gain anything (aside fro ride height) by running the 120/70---maybe I am thinking about this too much?

I have a set of 100mm dogbones on their way. Would that increase in height with the SRAD front and 120/60 be too screwy????

 

[FilthyRich]

anyone????

Right now I have a SRAD front end with a 120/60 and the rear shock raised only slightly. It's still pretty stable, though it shakes it's head more often now. I'm not going to raise the rear any more until I put a 120/70 on the front. I'm also looking for a steering damper just as insurance.
