I have a Baghira and a Sport, and both are well suited to distance riding-350 miles a day is easy (and i have done it numerous times). If anything, the Baggi's seat is a little more comfortable! Both will easily maintain 90mph all day long (stopping for fuel only, and a cigarette).
The only downside of both is lack of storage-throwover panniers don't work on either, as the pipes would melt them-so everything gets bungeed to the seat.
But, I am sure that there is a company somewhere that does aluminum panniers/top box for the Baggi?
