You can't keep the link brakes with F4i forks because the LHS 6th gen caliper mount has the link brake mastercylinder for rear brake & the mount on that fork leg for that system is completely different, you can't really use the 6th gen lower with the F4i because of the compression adjustment adjuster is on the lower F4i fork leg & the reason to upgrade the 6th gen forks with F4i is to gain remote rebound/compression adjustment they have & the 6th gen doesn't. To keep the link brakes & improve the standard forks there are kits aval to add rebound remote adjustment but honestly if you get your 6th gen forks valving & sring rate set up well the only real worth while upgrade is USD forks. Bellow is my 6th gen with CBR1000RR forks, I have sice installed my Ohlins CBR1000RR forks because the 25mm valving they have suits it better than the 30mm Ohlins cartridge kit in the forks in picture (the forks in picture are now installed on my CBR1000RR as the 30mm cartridges suit that bike better). The difference they make with handling & braking is like drinking your fav beer ice cold to the standard forks drinking it boiling hot. These are Ohlins forks on my CBR that are now on above & above now on CBR, the reason for swap is the 30mm valving is for heavy braking & high front end loading, the VFR doesn't load the front end anywhere near as much as a sportbike. show off....I want your Ohlins......*Renevator*....Where are you located at? I have locations on two R1 front ends as I am not going that direction and staying with the f4i fe. The front ends are complete and pretty reasonable. One is nicer than the other, but more $$
