Thread: R1200S a-arm swap

Shreddr, now you need to go ride a RT without the bags and then ride your S to compare the turn-in rate. I'm not sure if the RT A-arm totally duplicates the specs on the RT. You can do the test if you come down for the ECDR Spring Thaw.

The wheelbase of the R12R is advertised as 1495mm, which translates to 58.86" so it appears that the wheelbase is the same as the R12S. Comparing A-arms on the bikes (just did), the placement of the front attachment also appears to be the same. So even though the R feels like it has sharper turn-in, it's not because of wheelbase. Too bad, as the R has a steering damper so you wouldn't have to drill and tap a new hole.

Will offer more on this after I have a chance to get in the real curves with it. Trying it as an experiment... using Pilot Power... I didn't care for the 190/50 that came on the R12S stock. I went to 190/55 have been pleased with the improvement. Next time, you may want to give Bridgestone BT002 or...

I think he offered it on the trix site for 850 pounds for the set, but of course I have no idea what Ron paid for it.

yes, was not aware of the upper ball joint. thanks

Mine's on the way. Couldn't get them to throw in shipping on a $500 part. Thanks for the heads up. Now I'm going to have to get the Steve Carlton treatment done to my shocks as long as I'm in there. Won't be till after Thanksgiving though. I've got a track day at Willow coming up that weekend.

Quote: Originally Posted by shreddr the one thing i didn't mention before, but that is now very obvious to me is that the front shock will have to be dialed for this steeper front end. pulling the front end in puts more weight on it, which without shock adjustment will be too soft. assuming the spring rate is still correct (it should be close) besides getting the sag set right I think the shock might need additional compression damping,...
