Hey All

Having the front disc's changed on warranty due to warping then straight to Europe for a 2200 mile trip been back 2 weeks with an extra 300 miles disc's are warping again but more noticeable this time on hard braking , And also exhaust has rust on the weld spots and triumph have approved an warranty claim on this, A good bike but what else

Can't speak to the exhaust but my brother who is a dealer in four different marques (Triumph, Suzuki, Honda and Kawasaki) says that warped rotors are extremely common warranty claims across all brands.

I never experienced a warped disc on any on my bikes.

Yep, Very common problem on all bike brands. Had to replace them on my BMW K1300GT after 10k miles under warranty also! -Dr Ron

On the sprint ST the discs warp because the bobbins that allow the disc to float get gummed up.  In teh end after many times just spinning the bobbins to keep them free I went for EBC discs.

But really, I would not use BM as a yard stick for motorcycles mechanical flaws. Thats like polling the homeless to establish the median income for a city labor force.

I have 180,000Kms on my Concours/GTR1400 with the original discs, no warping.  Also, 110,000 kms on my Katana 750 with original front discs ( changed rear at 95,000Kms) with no warping. I use EBC brake pads on both bikes, no issues.

same here, after lots and lots of miles on lots and lots of bikes.

A theory I have:  no doubt some warped discs will happen (the percentage should very small though), but I believe motorcycle brakes need to get hot on a regular basis to operate properly.  I have known other riders to experience warped discs.  In all cases, they were too easy on the brakes.  It is actually good for the brakes, to act out like Rossi at stops once in a while.
