I think the KX Highs turned out to be the tallest that I could find the last time I bought some. I've also typically used two of the upper portion of clamps to raise them up even higher. I've just always hated feeling hunched over whiling standing.
And to try to stay on topic, I bought a pair...
Yeah but just think about how good it will feel if you keep the risers and Fastway pegs. I'm only 6'2", and have added these to about every bike that I've had. I'll bet this thing would feel soooo good with additional room. Hmm
What is this cleaning of air filters that you speak of? Never heard of it.
I think it depends on how long you plan to "store" it. It sounds like what you are doing may be fine. Maybe add a tender and some stabil.
