I have the grips, throttle boss, and lights. Great set up, wish I'd done it before. Bear in mind when you put the lights on the throttle boss, the bolts supplied are too short, and you will need to source some others elsewhere. I like the grips because they are nice and chunky, reduce vibration and look great. The throttle boss is just brilliant - it was sent in error instead of the lights, but I'm very glad I had it as well - so comfortable for long journeys. The lights are great, much safer and look different. The 'death grip' glue you get with the grips did not look enough, but if you put it in hot water before opening it it goes further. I attached mine to extend the bars by about and inch and a half each side, and moved the control up tight to them, making the bars quite a lot wider, and I love to riding position now.
It's all good....
