What I cannot understand, Triumph have known they have issues with the front rotors, I have had a good few now and have even had the front wheel replaced, the front caliper replaced and still the issues are there. I have upgraded the wheels to solid rather than spokes and twin rotors and up to now no issues. It certainly makes you think why the problems and why triumph cannot sort it out, maybe they think the more people that go for aftermarket parts, the less they'll stop winging at them.
