sweeet, sounds like a good idea to change them, when i nail my hornet the front goes light and floats a bit, bars shimmy a bit but thats normal, its at speed, the can get a bit wiggly, my mate with ultra low renthals doesn’t get the problem on his hornet, and he aint much bigger weight wise than me.
yeh will be ideal for track, give that extra bit of leverage for tipping in
measured the width of my bars today, just under 700mm, the ultra lows are about 730mm i think.
