This past March I made a 1,500 mile, 3-day trip from Florida to Tennessee to ride the "Dragon" (318 curves in 11 miles, but this area is full of other great rides) On the interstates I rode 80-90m.p.h. and in the mountains reasonably fast. Let's say m.p.g. was not a consideration. My average for the entire trip was 38.9m.p.g. (U.S.) - using Hitman's 1.201 conversion that is 46.7m.p.g (Imp. Gal). When I am really on the gas constantly I get about 36 U.S. or 43.2 Imp.
On another subject, I replaced the stock seat with a Corbin. They have heated or unheated versions. If any of you go to Daytona week, Corbin has a store a few miles north in Ormond Beach. They will put it on for you to see if you like it and then mail you your stock one for free. I find it a dramatic improvement, but be aware that Corbin makes a firm seat. If you want a soft one try a Russell.
I also put a laminarlip on the windscreen (see
www.laminarlip.com) which pushes the wind up about another two inches). Also use a Kwikover (a zip-out cover) - also purchased from laminarlip - that keeps the elements off on trips (like avoiding an ice covered seat on a cold mountain morning).
So far I can say that I am very pleased with my purchase (and add-ons).
I would post a photo, but I have not yet figured out how to do so (just started using this site). I also have a Triumph Daytona 1200SE and the Triumph site has a photo download function under "Additional Options" but it is not there for Kawasaki. Is this because I'm a "free" member, or am I missing something? The "insert image" icon does not seem to be for downloading a photo, but instead asks for a URL address. If anyone wants to give me a little instruction here it would be appreciated.
P.S. I forgot to add that my gas is a 10% ethanol blend and this hurts m.p.g. because it has less B.T.U. content than 100% gas. This is common in the states, and depends on what state you are in.
