Aw shucks! It's nuthin', bike did all the work!
We rented a little 100cc motorbike to carry us the 900km of our loop through Northwest Thailand. Which was at least 100cc too few for the hilly terrain. On some of the hills I would have the throttle fully opened and we would still slow to a pace that made keeping the bike upright difficult. Still, we made it and that little thing gets good mileage. Or is that Kilometerage?
