Thanks for posting, Sierra77! I'm not entirely convinced that is "Scura specific." The Scura Registrar can decide whether to let this topic run here in the registry. Otherwise, I would suggest we move it to 24/7 V11 and get some broader input and opinions about potential solutions.
Simple enough to start with tires (what make/model are you running, sizes (especially the rear), tire pressures, age of the tires?
Yet, I suspect we'll be getting into suspension set-up pretty quickly. First, where is your steering damper set?
Riding a little over 300 miles today, I thought about this a lot. Now, I'm more curious than ever. I can't imagine the Scura is harder to ride around than an 1100 Sport! Gotta be some simple set-up . . . make sure your steering damper is backed fully off, and air up the tires (I like 35/40). Fresh tires may help and a 170 on the rear instead of the stock 180 fitment may be helpful.
Let us know what you find!
