The 2006-2008 model R1 is not the most comfortable bike ever built thats for sure and altough it is a sports bike and a great track tool, for most owners it is important that you can ride one for more than half an hour without ending up in pain. Gilles make a fantastic product called Variobar. The ability to adjust the angle of the bars or even raise them higher than stock can fix the problem for most people. The Variobar for the 06-08 R1 is in fact 25mm higher than the stock. Some bikes you can fit an extra riser to the variobar but only of the fairing shape or fuel tank allows enough space to cope.
