Threw these on my 2018 R6 and went to a two day track event. Significantly improves brake predictability and keeps pressure/feel consistent throughout the day.
Only issues I have are that the front right brake line is a little too short. Even when not being held by the brake line clamp, the line stretches when turning left (noticed when checking clearance). If it had another cm it would be better. Also, when I had it in the brake line clamp, after one session the clear portion from the clamp down became white/discolored. Removed from clamp after noticing this.
Rear line to the master cylinder is a little too long when used with Vortex rear sets, and supplied rear banjo bolt does NOT fit (have to use OEM) so another thing to keep in mind!
