Default Front Brake Lockup WTF???

HI, had an usual event today with the 675r, went from current tune to 20596 just to see if much difference, went for a test ride & as I applied the brakes at end of street the fronts had a lot more feel to them, carried on & as I got further up the road, the bike started to struggle to keep moving, so pulled over & stopped, from this point the front brakes were on solid, could not move bike.After a while of rest & jiggling lever on & off they freed up enough to move & ride home. Now the lever feel seems "normal".?????????

I would take the front wheel off and look at the pads and calipers for anything loose or unusual.

How many miles on the bike?

I would take the lever off and clean/lube/reinstall. The pivot could be sticking, or the place where the M/C piston mates up could be shady. I've seen this happen to people when they poorly install a set of aftermarket levers. It's possible that your levers were installed poorly by the assembly tech.

Good call, guess I better recheck the aftermarket levers I installed

The ' nipple' for the m/c piston needs to be I'm the matching hole in the dowel inside the lever. You probably missed.

I was about to say have you done any work on the brakes recently, but there you go, you've answered your own question. I would have a thorough recheck at what you've done, as logically this is where the problem lies. Or at least the very first place you should be checking things.
