Just a little word of warning , I put the risers on mine and they definetly helped, i then put the touring seat on and that brought me forward a little more . But out in the middle of nowhere my clutch cable snapped it came away and frayed at the lever, I had no problems with it prior, and it was rerouted on the outside , i may have been unlucky , it happening but i was lucky there was a good samaratin who got me going , with a makeshift cable i had to cut my holiday short and go straight home , nearest triumph dealer was a few hundred klm and a 5 day wait to get a cable .
I went home and the dealer replaced it under warranty , but if i put the risers back on i will definetly get a longer clutch cable , for the sake of a few dollars i would'nt want to risk it happening again , a mate had the risers on, and his cable was begining to frey has well ,he only spotted it when he got round to changing to a longer cable .
Also if anyone his thinking of putting the risers on , i've found now with the longhaul seat the bike is actually quite comfortable without the risers.
So my advice would be to buy the seat if first , if your thinking of purchasing both seat and risers. , if its the risers only , like i said i personaly feel that its alright for a while but theres a tad to much strain on the cable.. my bike was at 22,000 klm when it happebnned so i had done approx 20,000 on the old cable
