T
here is a reason why big-bore kits are so popular
with 250Fs these days. Actually, there are many
reasons: They boost engine performance big-
time, they make riding 250Fs a lot more fun, they are
relatively simple to install (if you know what you're do-
ing or know someone who does and is willing do the
work for you, then it's really simple), and they are far
cheaper to buy than a new bike. And for many, big-bore
kits are the answer to 450s that are just too much and
250Fs that are not big enough. As a results, 250F big-
bore kits have become very popular with the veterans
who don't need 450 power but want a little more oomph
and torque than a stock 250F for racing in the vet di-
vision, where classes are usually determined by age,
not engine size. Big-bore kits are also very popular with
pros who want a practice bike that mimics the power
output of their heavily modiļ¬ed 250cc race bikes and
want something that will last a lot longer than their high-
ly-strung race engines. And, of course, big-bore kits are
also popular with cheaters. (You know who you are and,
yes, we hope you have trouble sleeping at night.)
