When I first discovered the sire I noticed the Suzuki and the other japanese brand forums were not very wel travelled. ekaphoto and I livenewd it up for a while then I took a hiatus. Its winter now so my interesets have returned to internet things.
I ride a DRZ (out of several bikes I have) and love it. So hopefully we can liven the Suzuki site up again.
But as mentioned before. For a lot of straight technical info thumpertalk.com has a huge library of postings already.
