Well RC51 front end was a success so here it is:
completely rebuilt f4i forks (less than 1k miles ago) with new bushings/seals and Ohlins oil. Forks were upgraded with Gold valves and custom shim stack and Race tech springs. Sliders were polished to reduce stiction. They were tuned for 185-215 lbs rider.
Fork have adjustable preload, compression and rebound demping.
Just in parts: gold valves -$170
RT springs -$110
Ohlins fluid -$35
+ forks themselves, seals, bushings and $$$ labor + fender
$450 + shipping (should be around $25 or so) This price includes front custom fender. Forks are 20 min direct bolt on.
