BMW HP2
Glassett's Adventure Bike
BMW HP2 The motorcycle to reset the Adventure attitude:
My new BMW HP2, Ocotillo Wells Pumpkin Patch (First ride November 2005)
HP2 at the Grand Canyon (Bar10 Ranch 2006)
Stuck in the Mud on the Great Divide Ride (Somewhere in New Mexico 2006)
I needed more range, So I built an additional fuel tank under the seat, Check out the photos below:
The Tank fits uder the seat and adds a little more then 2 gallons additional. It fits between the frame rails and being black it is hardly noticable. There is an additional fuel pump that pumps fuel during fullup from the main tank to the additional tank. The fuel pump is reservable with a toggle switch and pumps the additional fuel back to the main tank when low.
Pictures below are from the prototyping process.
The final tank is made from 0.040" galvanized steel. Steel was chosen because it can be made much thinner then alaminum and will servive the years of Fatgue much better. The weight ends up very close to aluminum. Which is only about 5lbs.
As I have been using the tank now, the bike now goes more then 215 miles and fill up is as much as 5.3 gallons for the system. I now have about 5000 mikes of rough use on it and it has been great. See the Great Divide Ride page for my fun testing program.
I recommend you make one yourself. Enjoy the ride!
I also added a windshield, GPS, and bags, for longer adventures
