Listening to the talk about fatter tires. I realize this is "fashionable" in some quarters, but need to point out (because apparently many don't know) that NARROW TIRES CORNER BETTER on the light Enfield type bikes. Lets be clear, there all are kinds of pictures of just about everything to be seen, but that doesn't mean they work any better. Like a certain V-twin motorcycle I won't name, that is more about theater than performance. Yes, the racers use some fatties on small wheels, but they also have the horsepower to make use of the bigger foot print. On a light bike a bigger footprint will aquaplane easier than a small footprint in the wet. It will not bite enough to improve performance-only make handling sluggish. I would not put anything bigger than a 3.25 on the front, or a 3.50 on the rear of a Royal Enfield. I also prefer the 19" wheels on the G5 series, as they allow better ground clearance during sporty cornering. Guess you need to decide wether you want a chopper, a cruiser, or a nimble motorcycle with classic ancestry. You should always question the wisdom of what the other Primates are doing, before before you follow their example.
