i just ordere the rc Calypso rear also i have the 21 front already on decided i need the rear ordered it from wanaryde chuck there told me to stick with the 17 rea as people with the 18 complain of high speed wobble with it
I wondered why they used a 17" rear for the 200 on my bike. I never heard the high speed wobble thing before. I am running an 18"x4.25" rear on my '07 but it's only got a 150/60/18 on there. No high speed issues with either.
