Just fitted new risers to my Speedmaster Together with the tracker bars gives the best riding position for me. Pullback on risers just enough to take the reach of the bars to ideal place. Odd mix of fasteners on these risers, metric M8 for the top clamps, imperial 1/2" UNC for the yoke mounting bolts. Good finish though in polished satinless steel
No all cables and brake line standard, pulled a bit of slack on the electrical cables from under the tank.
I fitted the Motone risers to my speedmaster. Install was easy and no cable issues. Really improved the comfort level as I was not a fan of the stock bars and risers. I would like to fit a set of old Harley bars but not sure if the throttle end would work or not. The Harley bars are 1 inch like the triumph bars. Also think the mid foot controls would really improve comfort.
The bars I have on at the moment are universal bars, no issues, although you will need to drill 10mm hole for throttle location pip which is on inside of right hand bar fitting. Everything else fits straight on.
