First off thanks for everything guys, your help has been great, i just ordered a 351 kit today, and will slap it on next weekend. Anyways, i was wondering what the suspension difference between the 2009 klx250s suspension and the klx250sf suspension was. I always bottom out on my SF, and as recommended by my friend get some shorter links that would help. But someone said something about a spacer on the SF? And how does the newer bike compare to the 2006 klx? And is it really bad to bottom out my klx? Thanks, i could really use some better suspension.
