How far can I extend my front end before my bike handles bad?
How much rake should I put on it? These are probably the two questions most
often asked
by a guy starting to get a chopper together, and both questions fall into
the same category as "how high is up?" A better way of putting
would be: "what length and rake will make my bike handle better than
stock?"
That's right brother. Done right your bike should handle better than stock
when being used for the purpose for which you are building it which is usually
highway jammin’. Now if your planning on running your chopper in a
moto-cross, your head is in your ass anyway, so just shine it on. The result
would be like saying a Rolls Royce didnt handle or ride worth a dam just
because a porche shut it down through a slalom course. Whenever you build
something for a specific purpose, it has to suffer a little somewhere else,
and this holds true for long forks. Generally speaking, the longer you go,
and the more degrees of rake you put in your frame, the better your bike
will handle at highway speed in a straight line; you suffer slightly at low
speed and through tight corners, as does a rolls or a Cadillac. (The quality
of the fork you are using is very important; if the constuction of the fork
allows it to flex around like piece of wet spaghetti, your’e going
to have handling problems, no matter what.)
There are other things to consider along with the handling characteristics,
such as size of wheels, tires, weight, handlebar leverage, and ground clearance.
These
in turn, should be decide upon with weight, height, strength, and favored riding
position of the owner in mind. Remember that you are not going racing; you’re
goin’ puttin’ to enjoy your self, and you can do this best if you’re
comfortable.
There is always, of course, Denny Dumfuk who isn’t happy unless he’s
the most, the hairiest, the biggest, highest, etc. He’s the guy who got
ape hangers outlawed for us. What can I say? You can overdo anything. But lets
look at the positive side. Take, for example, a stock full-dress ’52 hog
and put it up against a chopped version with a 16 on the rear, 8- inch over narrow
springier up front with a 3.00x21 Avon. I’ll bet a $ 100 bill against a
weeks use of your ol’ lady that the chop will crap all over the dresser
on a tight mountain road. Why? Light weight; ground clearance; firmer, more responsive
fork; and better weight distribution. True, an 8 inch fork isn’t very long
by today’s standards, but I would guesstimate you could go 14 inches with
a 3/4-inch rake before you went so far as to lose ground to the stocker. Even
16, 18, and 20 over with up to 1 3/4-inch rake is believable if its set up right
and
all
factors
are given careful consideration.
