My friend has a set of steel braided lines that he never put on his F4i do you think they would fit the RC ? It would be nice to have a set on the bike . My last bike had them and I think it is one of the best things to do I figure if they fit I could save a few bucks.
It might work.
The rear caliper is the same.
Just measure the distance needed from the master cylinder to the caliper for enough length.
For the fronts, also check the length needed and if they will route to the master cylinder properly. The calipers are similar design as maybe the master cylinder.
