It all depends on what you're after; easy bolt-on, looks, footpeg location, folding or non folding, solid or rubber mount, passenger peg compatability and so it goes on. I would agree with Grizld in that Raask are c**p. TC bros and Tarozzi would be more or less bolt on, Fast From The Past stock Tarozzi. Now, Tarozzi are quite heavy, and Tarossi and TC Bros both have the pegs too far back for my taste. They both also are mounted solid.......
I am building my own rubber mounted plates, with pre-75 XS pegs located halfway between the mounting studs. This is my personal preference, for a balanced riding position and period look. Both pedals are self-made of polished stainless steel.
Last January I saw an XS at Phillip Island in Australia with modified stock pegs located like this. He had just cut down the stock mounts, and welded the stock hinge part on, centered between the studs. He also had welded on a gear lever pivot mount, and relocated the brake pivot. It all looked almost stock, and reused pegs and brake pedal.
If low weight, modular system and a more modern look is desirable, I strongly recommend LSL from Germany. Super light, anodised alloy, solid or spring loaded pegs, just mix & match pegs and pedals as required.
