John,
I dont know that they are lower than the stock pegs. If they are then not by much, but it is noticeably lower from my riding position. the pegs are a smaller outside diameter than stock so that my be the cause. The pegs are also longer than stock a will scrape the ground on tight turns while leaning the bike.
I did have to get a shorter linkage. Stock I believe was 15" where as my new one is 9 or 10" I believe some people were able to use the stock linkage. I believe Hollywood also has them. I believe he retained the stock linkage.
