forkbrace?

[NightRider_imp]

I have two on my 14 non-standard bike. I mark the measurements roughly with a felt tip pen and grind down the fork gaiters until they just fit. After doing this I can reach 140 mph without shifting and I experience zero instability problems and vibrations. I don't have to put air in my tires saving lots of time before leaving for my ride.
...and as somebody else said, it is pretty and if one is pretty then two are prettier.
