I Had anti-vibe Rox risers and grip puppies on my 2011 tiger, it vibrated badly, dealer would not fix so in the end I got pissed off with it and sold it, back then I had loads of customers with the same problem, seems that Triumph had their tolerance problems sorted by 2012 though, if they had changed or rebuilt the engine I would have kept that bike, the lesson for me was never buy a bike when it first comes out, BMW R1200GS-LC was another example, 2013 models were terrible
Anyway both help, I always fit grip puppies to all my bikes, makes them much more comfortable and the heated grips still work
Cheers
