They are different levers on the RS (as opposed to the previous R). The brake lever is a Brembo MCS 19:21 with a matching clutch lever (as you'd expect). They're painted black (powdercoat?) and in my case, the black had worn away (not excessively), creating the dust that had contributed towards binding up the mechanism. My brake lever failed too - the '19:21' modulation wheel wouldn't rotate. It was replaced under warranty and as you suggest, and it came as an entire assembly which included the master cylinder and possibly even the brake line (or so I was told by the dealer). I didn't have much luck with the Brembo premium parts!
Yes, my opinion of Italian engineering - nearly always stylish, sometimes clever / eccentric, often sold on the afore mentioned attributes, rarely for quality and reliability.
Hi, mine has this issue too and yes, my dealer did not sound surprised and said it probably isn't cable adjustment. Deffo s known fault. The lever isn't returning properly.
So I took mine it and it was definitely the lever sticking. The dealer contacted Triumph and their recommendation was to take the perch apart clean/lube and tighten to spec. Its like brand new again. I advise you to do this if you're even a little bit mechanically inclined, that way it doesn't have to sit in the shop unnecessarily...
My Thruxton R had the same issue. Lubed the clutch lever pivot point & all is good. You should have a bit of slack in the lever anyway. Every time you ride just push lever away fro grip to check all is ok, it will spring back. If it doesn't then lube it
I've just had this issue with my RS. It turned out that the clutch lever thru bolt was over tightened and also needed some lube on the pivot as mentioned in earlier posts. Not too impressed that this seems to be quite common straight out the factory.
Exactly that - even reported by a journalist that was test riding an RS at the time of its launch. Shame it doesn't seem to have been recognised as something that needs addressing. At least it's one of the easier things you'll ever have to fix
