Triumph did this so you wouldn't have to wear out the stock brake pads so quickly. Same reason they installed a 17 tooth counter sprocket the first few years. Saves the brake pads for the twisties where the wear and tear is worth it--or so I hear. Kinda hard to find very good twisties out here in the flat lands. :-D 17900 miles and I still have 75% of the original pads left--now tires are another matter...time for the third set.
