OK, I know this is a 919 only forum and all, but the bill for the suspension rework by LE is $1300+...
Not sure if these can be adapted to fit a 919, but there is a ton of parts for them out there (triple clamps, wheels, calipers, etc...).
I put them up for sale at WERA forum for 140 + shipping.
WT members can get them for 100 + shipping.
I'll be putting them up for sale on the gsxr forum once my 30 day probation is over in a week.
They'll go quick there, lots of stuntas and posers...
