front end conversion??

[R1madness]

The 600 springs are too stiff for a Bros. And the damping rates still need changes to suit the bros. The 400 one is a simple conversion. The spring rate is very close and the dampining only needs slightly heavier oil (make your own 12wt by mixing 10wt and 15wt)

Use a CBR400RR front end. Otherwise you are just wasting your time and money. There is no point putting a 16 inch front wheel on, It will stuff the handling up and you can only get average tyres. The whole point of changing the front end should be (styling aside) to improve the handling and brakeing ability. If you use the VFR forks (unless it is NC30) you will not get much inprovement over the BROS ones and will need to make addaptors for the bros wheel to fit. So no improvement to brakeing due to still having a single disk. Sounds like a lot of hassle for very little improvement.

thanks thats what im wanting to know.

the forks are bent but they are pepairable, i was considering having the originals fixed then using racetech progressive springs and racethech gold valve emulators. i'll be on the look out for a cbr400 front end though

Not sure the VFR forks are any better than yours, unless yours are bent after your biff. How about fitting the Bros motor in the VFR rolling chassis?

ah the forks are bent.

there isnt much size diff between the vfr and bros though so whats the point? i might just buy that vfr to do the engine as a project
mmmmm ported v4
