I bought these: http://www.ebay.co.uk/itm/301121738503? ... 1439.l2649
For my R1 and I must say what a nice piece of kit. They are adjustable for height, angle and length, the tubes are loose so you can replace them if they break and everything is nicely machined with nice bolts.
Well worth the money. I haven't driven the bike with them on but I bet it will be comfier.
