Back in the late sixties I started out on singles, excessive vibration drove me fairly quickly to twins. Then started getting interested in some fours then tried a six, then back to fours a couple more twins. Finally the last six have been singles again.
Light Torquey Bikes Rule the Twistys. I love bikes that weigh Under 300 lbs Fully Gassed, I feel I can wrestle 272 pounds easier than 400+ pounds.
