Seasider very useful comments especially if we both have the same body characteristic. I want to improve the long rides comfort and have this nice flexibility of f800 if the asphalt ends suddenly... D3 seems to be solution. The noise for me is also a riding safety issue as it affects the driver concentration after some time of riding. The cost is an issue as well but if I plan to use the bike for long time .... Thank you for your comments. Me starting negotiating with Santa...
