Come on Tone!
Get some angle iron and lag bolts and make it happen!
I wonder how easily this would slip into a KLR650 chassie, not that I even like them. I had one and hated it, but the 300 would be a better power plant and 6g of fuel could give a range of 500 miles or more. Might be neat and they have the 650 twins fitting there very cleanly.
