Fitted a larger throttle tube today It's an R6 one that I've had fitted to all my bikes before Must say it is a great improvement on the standard Triumph one...To get to wide open throttle before felt like my wrist was under the bar Bike feels a lot better (quicker) in the midrange using my normal hand movement I can now get a move on without looking like a 12 year old on an arcade machine whacking the throttle wide open ha ha ha
I haven't mate sorry..... It was a throttle tube I bought years ago If you Google 1/5th Turn R6 throttle then loads of forums have the part numbers
Another option, but expensive, is G2 ergonomics. They are based in the USA and have a wide range of street or dirt and competition throttles. A lot were sold to MT09 owners trying to tame the snatchy throttle of the original bike.
