I'm looking at purchasing a 2010 XF 800 SP. As I am fairly tall, the handlbars are still low for me when standing, even when they are fully extended. My dealer says a riser can't be installed on telescopic bars. Ideally, I would like at least a 2 possibly 3 inch riser installed. Has anyone done so and is it difficult as it appears the cables are all fixed in place on the bars.
