Just went on a 95 mile ride (GPS verified) on the B&W300 with my girlfriend on her People S200. Rode from Portland to Larch Mtn about 4000 ft climb, the Bet and Win averaged 70.2 MPG and the S200 was 85.7 mpg!!!! I was super surprised, such a step climb and half of it was slow city driving. The S200 has a 30mm cvk from a 250 Kymco, open exhaust, a12 camshaft goes faster than stock and gets better mileage!!!! My bike didn't do to bad considering it has a 300cc kit, cam, and exhaust. I would track my mileage more but my odometer is 5% off. I used 1.3 gallons to go 95 miles, meaning that if I had to push my luck i could go over 200 miles on a tank!
