Truly enjoyable read! For some reason I have an affinity for the DR350's. I think Suzuki made a huge mistake when they went to a 5-speed in the DRZ, and they seem poised to make the same mistake if they make a DS version of the RMX-Z. I love the idea of dropping the 6th from the 250 into it. You may have built the ultimate Dual-Sport machine when this is complete.
